# Objective
The view uniform lacks view transform information. The inverse transform is currently provided but this is not sufficient if you do not have access to an `inverse` function (such as in WGSL).
## Solution
Grab the view transform, put it in the view uniform, use the same matrix to compute the inverse as well.
# Objective

In [this commit](a52f755ce8), the signature of `run_return` was changed in winit.
## Solution
This tiny PR does not add support for exit code, but makes compilation successful.
# Objective
- `CoreStage::Startup` is unique in the `CoreStage` enum, in that it represents a `Schedule` and not a `SystemStage`.
- This can lead to confusion about how `CoreStage::Startup` and the `StartupStage` enum are related.
- Beginners sometimes try `.add_system_to_stage(CoreStage::Startup, setup.system())` instead of `.add_startup_system(setup.system())`, which causes a Panic:
```

## Solution
- Replace the `CoreStage::Startup` Label with the new `StartupSchedule` unit type.
Resolves#2229
# Objective
The docs for `{VertexState, FragmentState}::entry_point` stipulate that the entry point function in the shader must return void. This seems to be specific to GLSL; WGSL has no `void` type and its entry point functions return values that describe their output.
## Solution
Remove the mention of the `void` return type.
# Objective
- Currently, when getting a diagnostic value, the oldest value is returned. This is not the best for a diagnostic with a large history, as you could get a value from several frames away
## Solution
- I changed the order in which the history is used to follow ["The “default” usage of this type as a queue is to use push_back to add to the queue, and pop_front to remove from the queue."](https://doc.rust-lang.org/std/collections/vec_deque/struct.VecDeque.html)
# Objective
- `serde_json` assumes that numbers being deserialized are either u64 or i64.
- `Entity` serializes and deserializes as a u32.
- Deserializing an `Entity` with `serde_json` fails with: `Error("invalid type: integer 10947, expected expected Entity"`
## Solution
- Implemented a visitor for u64 that allows an `Entity` to be deserialized in this case.
- While I was here, also fixed the redundant "expected expected Entity" in the error message
- Tested the change in a local project which now correctly deserializes `Entity` structs with `serde_json` when it couldn't before
# Objective
- Fix#3559
- Avoid erasing existing resource `Assets<T>` when adding it twice
## Solution
- Before creating a new `Assets<T>`, check if it has already been added to the world

# Objective
- Bevy currently has no simple way to make an "empty" Entity work correctly in a Hierachy.
- The current Solution is to insert a Tuple instead:
```rs
.insert_bundle((Transform::default(), GlobalTransform::default()))
```
## Solution
* Add a `TransformBundle` that combines the Components:
```rs
.insert_bundle(TransformBundle::default())
```
* The code is based on #2331, except for missing the more controversial usage of `TransformBundle` as a Sub-bundle in preexisting Bundles.

Implements a new Queryable called AnyOf, which will return an item as long as at least one of it's requested Queryables returns something. For example, a `Query<AnyOf<(&A, &B, &C)>>` will return items with type `(Option<&A>, Option<&B>, Option<&C>)`, and will guarantee that for every element at least one of the option s is Some. This is a shorthand for queries like `Query<(Option<&A>, Option<&B>, Option<&C>), Or<(With<A>, With<B>, With&C>)>>`.

# Objective
Enable the user to specify any presentation modes (including `Mailbox`).
Fixes#3807
## Solution
I've added a new `PresentMode` enum in `bevy_window` that mirrors the `wgpu` enum 1:1. Alternatively, I could add a new dependency on `wgpu-types` if that would be preferred.
## Objective
When print shader validation error messages, we didn't print the sources and error message text, which led to some confusing error messages.
```cs
error:
┌─ wgsl:15:11
│
15 │ return material.color + 1u;
│ ^^^^^^^^^^^^^^^^^^^^ naga::Expression [11]
```
## Solution
New error message:
```cs
error: Entry point fragment at Vertex is invalid
┌─ wgsl:15:11
│
15 │ return material.color + 1u;
│ ^^^^^^^^^^^^^^^^^^^^ naga::Expression [11]
│
= Expression [11] is invalid
= Operation Add can't work with [8] and [10]
```
# Objective
Add a simple way for user to get the size of a loaded texture in an Image object.
Aims to solve #3689
## Solution
Add a `size() -> Vec2` method
Add two simple tests for this method.
Updates:
. method named changed from `size_2d` to `size`
# Objective
- `asset_server.watch_for_changes().unwrap()` only watches changes for assets loaded **_after_** that call.
- Technically, the `hot_asset_reloading` example is racey as the watch on the asset path is set up in an async task scheduled from the asset `load()`, but the filesystem watcher is only constructed in a call that comes **_after_** the call to `load()`.
## Solution
- It feels safest to allow enabling watching the filesystem for changes on the asset server from the point of its construction. Therefore, adding such an option to `AssetServerSettings` seemed to be the correct solution.
- Fix `hot_asset_reloading` by inserting the `AssetServerSettings` resource with `watch_for_changes: true` instead of calling `asset_server.watch_for_changes().unwrap()`.
- Document the shortcomings of `.watch_for_changes()`
# Objective
The query for `VisiblePointLights` in `check_light_mesh_visibility` has a `Without<DirectionalLight>` filter. However, because `VisiblePointLights` is no longer an alias for `VisibleEntities`, the query won't conflict with the query for `DirectionalLight`s and thus the filter is unnecessary.
## Solution
Remove the filter and the outdated comment explaining its purpose.
# Objective
- Provide impls for mutable types to relevant immutable types.
- Closes#2005
## Solution
- impl From<ResMut> for Res
- impl From<NonSendMut> for NonSend
- Mut to &/&mut already impl'd in change_detection_impl! macro
# Objective
- `Name` component is missing some useful trait impls.
## Solution
- Implement the missing traits. `Display`, `AsRef<str>`, and several other conversions to and from strings.
# Objective
It would be useful to be able to restart a state (such as if an operation fails and needs to be retried from `on_enter`). Currently, it seems the way to restart a state is to transition to a dummy state and then transition back.
## Solution
The solution is to add a `restart` method on `State<T>` that allows for transitioning to the already-active state.
## Context
Based on [this](https://discord.com/channels/691052431525675048/742884593551802431/920335041756815441) question from the Discord.
Closes#2385

# Objective
- As part of exploring input event suppression in bevy_egui here: 53c1773583
- I found that the only way to suppress events properly, is to allow to clone the relevant Input<Whatever>, and update with events manually from within the system. This cloned Input then is discarded, the Events<*> structs are cleared, and bevy_input's normal update of Input proceeds, without the events that have been suppressed.
## Solution
- This enables Input to be cloned, allowing it to be manually updated with events.
Implements the changes cart decided on in https://github.com/bevyengine/bevy/pull/3404#issuecomment-999806086
> - The default title should be changed to app so we don't leak the "bevy context" by default. app is generic enough that most people building real games will probably want to change it, but also generic enough that if someone doesn't manually set it, users won't bat an eye. I prefer this to binary names because they won't be consistent on all platforms / setups. A user (or developer) renaming a binary would implicitly rename the window title, which feels odd to me.
> - No debug info in the title by default. An opt in plugin for that would be nice though.
closes#3404 ?
# Objective
Fixes#3250
## Solution
Since this panic occurs in bevy_ecs, and StartupStage is part of
bevy_app, we really only have access to the Debug string of the
`stage_label` parameter. This led me to the hacky solution of
comparing the debug output of the label the user provides with the known
variants of StartupStage.
An alternative would be to do this error handling further up in
bevy_app, where we can access StartupStage's typeid, but I don't think
it is worth having a panic in 2 places (_ecs, and _app).
# Objective
- Missing obvious way to rotate a transform around a point. This is popularly used for rotation of an object in world space ("orbiting" a point), or for local rotation of an object around a pivot point on that object.
- Present in other (not to be named) game engines
- Was question from user on Discord today (thread "object rotation")
## Solution
- Added Transform::rotate_around method where point is specified in reference frame of the parent (if any) or in world space.
# Objective
When using empty events, it can feel redundant to have to specify the type of the event when sending it.
## Solution
Add a new `fire()` function that sends the default value of the event. This requires that the event derives Default.

# Objective
Make it possible to use `&World` as a system parameter
## Solution
It seems like all the pieces were already in place, very simple impl

# Objective
Provide a non-consuming method of checking if there are events in an `EventReader`.
Fixes#2967
## Solution
Implements the `len` and `is_empty` functions for `EventReader` and `ManualEventReader`, giving users the ability to check for the presence of new events without consuming any.
Co-authored-by: Carter Anderson <mcanders1@gmail.com>
# Objective
Calling forget would invalidate the data pointer before it is used.
## Solution
Use `ManuallyDrop` to prevent the value from being dropped without moving it.
This is my first contribution to this exciting project! Thanks so much for your wonderful work. If there is anything that I can improve about this PR, please let me know :)
# Objective
- Fixes#2899
- If a simple one-off command is needed to be added within a System, this simplifies that process so that we can simply do `commands.add(|world: &mut World| { /* code here */ })` instead of defining a custom type implementing `Command`.
## Solution
- This is achieved by `impl Command for F where F: FnOnce(&mut World) + Send + Sync + 'static` as just calling the function.
I am not sure if the bounds can be further relaxed but needed the whole `Send`, `Sync`, and `'static` to get it to compile.
# Objective
A user on Discord couldn't derive SystemParam for this Struct:
```rs
#[derive(SystemParam)]
pub struct SpatialQuery<'w, 's, Q: WorldQuery + Send + Sync + 'static, F: WorldQuery + Send + Sync + 'static = ()>
where
F::Fetch: FilterFetch,
{
query: Query<'w, 's, (C, &'static Transform), F>,
}
```
## Solution
1. The `where`-clause is now also copied to the `SystemParamFetch` impl Block.
2. The `SystemParamState` impl Block no longer gets any defaults for generics

# Objective
Fixes#3566
## Solution
- [x] Fix broken links in private docs.
- [x] Add the `--document-private-items` flag to the CI.
## Note
The following was said by @killercup in #3566:
> I don't have time to confirm this but I assume that linking to private items throws an error/warning when just running cargo doc, and --document-private-item might actually hide that warning. So to test this, you'd have to run it twice.
I tested this and this is thankfully not the case. If you are linking to a private item you will get a warning no matter if you run `cargo doc` or `cargo doc --document-private-items`.
### Example
I added `struct Test;` to `bevy_core/src/name.rs` and linked to it inside of a doc comment using ``[`Test`]``. After that I ran `cargo doc -p bevy_core --document-private-items` using `RUSTDOCFLAGS="-D warnings"` and got the following output (note the last sentence):
```rust
error: public documentation for `Name` links to private item `Test`
--> crates/bevy_core/src/name.rs:11:82
|
11 | /// Component used to identify an entity. Stores a hash for faster comparisons [`Test`]
| ^^^^ this item is private
|
= note: `-D rustdoc::private-intra-doc-links` implied by `-D warnings`
= note: this link resolves only because you passed `--document-private-items`, but will break without
```
# Objective
- Update the `ClearColor` resource docs as described in #3837 so new users (like me) understand it better
## Solution
- Update the docs to use what @alice-i-cecile described in #3837
I took this one up because I got confused by it this weekend. I didn't understand why the "background" was being set by a `ClearColor` resource.
# Objective
Currently, simply calling `iter` on an event reader will mark all of it's events as read, even if the returned iterator is never used
## Solution
With this, the cursor will simply move to the last unread, but available event when iter is called, and incremented by one per `next` call.

# Objective
I think the 'collide' function inside the 'bevy/crates/bevy_sprite/src/collide_aabb.rs' file should return 'Some' if the two rectangles are fully overlapping or one is inside the other. This can happen on low-end machines when a lot of time passes between two frames because of a stutter, so a bullet for example gets inside its target. I can also think of situations where this is a valid use case even without stutters.
## Solution
I added an 'Inside' version to the Collision enum declared in the file. And I use it, when the two rectangles are overlapping, but we can't say from which direction it happened. I gave a 'penetration depth' of minus Infinity to these cases, so that this variant only appears, when the two rectangles overlap from each side fully. I am not sure if this is the right thing to do.
Fixes#1980

# Objective
- While it is not safe to enable mappable primary buffers for all GPUs, it should be preferred for integrated GPUs where an integrated GPU is one that is sharing system memory.
## Solution
- Auto-disable mappable primary buffers only for discrete GPUs. If the GPU is integrated and mappable primary buffers are supported, use them.
# Objective
In order to create a glsl shader, we must provide the `naga::ShaderStage` type which is not exported by bevy, meaning a user would have to manually include naga just to access this type.
`pub fn from_glsl(source: impl Into<Cow<'static, str>>, stage: naga::ShaderStage) -> Shader {`
## Solution
Re-rexport naga::ShaderStage from `render_resources`
# Objective
- Test is failing on nightly after the merge of https://github.com/rust-lang/rust/pull/90247
- It was relying on the precision of the duration of `1.0 / 3.0`
## Solution
- Fix the test to be less reliant on float precision to have the same result
This PR is part of the issue #3492.
# Objective
- Add crate level docs to the bevy_log documentation to achieve a 100% documentation coverage.
- Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.
# Solution
- Add and update the bevy_log crate level docs
- Add a note about panicking from multiple `LogPlugins` per process.
- Add the #![warn(missing_docs)] lint.
# Objective
- Calling .id() has no purpose unless you use the Entity returned
- This is an easy source of confusion for beginners.
- This is easily missed during refactors.
## Solution
- Mark the appropriate methods as #[must_use]
# Objective
- Users can get confused when they ask for watching to be unsupported, then find it isn't supported
- Fixes https://github.com/bevyengine/bevy/issues/3683
## Solution
- Add a warning if the `watch_for_changes` call would do nothing
# Objective
- Fixes#3562
## Solution
- The outdated reference to `TextGlyphs` has been removed, and replaced with a more accurate docstring.
## What was `TextGlyphs`?
This is the real question of this Issue and PR. This is particulary interesting because not only is `TextGlyphs` not a type in bevy, but it _never was_. Indeed, this type never existed on main. Where did it come from?
`TextGlyphs` was originally a tuple struct wrapping a `Vec<PositionedGlyph>`. It was first introduced back in commit ec390aec4e in #765. At the time, position information was being stored on the text entities directly. However, after design review, [it was decided](https://github.com/bevyengine/bevy/pull/765#issuecomment-725047186) to instead store the glyphs in a `HashMap` owned by the `TextPipeline`. When this was done, the original type was not only removed, but abstracted behind a few layers of the `TextPipeline` API. Obviously, the original docstring wasn't updated accordingly.
Later, as part of #1122, the incorrect docstring was swept up when copy/pasting `text_system` for `text2d`. (Although I don't blame @CleanCut for this; it took me like 3 hours to track all this down to find the original context.)
# Objective
- Allow opting-out of the built-in frustum culling for cases where its behaviour would be incorrect
- Make use of the this in the shader_instancing example that uses a custom instancing method. The built-in frustum culling breaks the custom instancing in the shader_instancing example if the camera is moved to:
```rust
commands.spawn_bundle(PerspectiveCameraBundle {
transform: Transform::from_xyz(12.0, 0.0, 15.0)
.looking_at(Vec3::new(12.0, 0.0, 0.0), Vec3::Y),
..Default::default()
});
```
...such that the Aabb of the cube Mesh that is at the origin goes completely out of view. This incorrectly (for the purpose of the custom instancing) culls the `Mesh` and so culls all instances even though some may be visible.
## Solution
- Add a `NoFrustumCulling` marker component
- Do not compute and add an `Aabb` to `Mesh` entities without an `Aabb` if they have a `NoFrustumCulling` marker component
- Do not apply frustum culling to entities with the `NoFrustumCulling` marker component
# Objective
- Do not panic when mroe than 256 point lights are added the scene
- Fixes https://github.com/bevyengine/bevy/issues/3682
## Solution
- Only iterate the first `MAX_POINT_LIGHTS` lights instead of as many as there are
## Open questions
- Should we warn that there are more than the maximum allowed number of point lights in the scene?
# Objective
- When using `WgpuOptionsPriority::Functionality`, which is the default, wgpu::Features::MAPPABLE_PRIMARY_BUFFERS would be automatically enabled. This feature can and does have a significant negative impact on performance for discrete GPUs where resizable bar is not supported, which is a common case. As such, this feature should not be automatically enabled.
- Fixes the performance regression part of https://github.com/bevyengine/bevy/issues/3686 and at least some, if not all cases of https://github.com/bevyengine/bevy/issues/3687
## Solution
- When using `WgpuOptionsPriority::Functionality`, use the adapter-supported features, enable `TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES` and disable `MAPPABLE_PRIMARY_BUFFERS`
# Objective
Fixes#3613
[Link to issue](https://github.com/bevyengine/bevy/issues/3613)
## Solution
Changed the Deref Target to `str` and changed the `deref()` function body so that a `&str` is returned by using `as_ref() `.
Fixed doc comment where render Node input/output methods refered to using `RenderContext` for interaction instead of `RenderGraphContext`
# Objective
The doc comments for `Node` refer to `RenderContext` for slots instead of `RenderGraphContext`, which is only confusing because `Node::run` is passed both `RenderContext` and `RenderGraphContext`
## Solution
Fixed the typo
This PR is part of the issue #3492.
# Objective
- Add and update the bevy_tasks documentation to achieve a 100% documentation coverage (sans `prelude` module)
- Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.
## Solution
- Add and update the bevy_math documentation.
- Add the #![warn(missing_docs)] lint.
- Added doctest wherever there should be in the missing docs.
# Objective
Emitting compile errors produces cleaner messages than panicking in a proc-macro.
## Solution
- Replace match-with-panic code with call to new `bevy_macro_utils::get_named_struct_fields` function
- Replace one use of match-with-panic for enums with inline match
_Aside:_ I'm also the maintainer of [`darling`](https://docs.rs/darling), a crate which provides a serde-like API for parsing macro inputs. I avoided using it here because it seemed like overkill, but if there are plans to add lots more attributes/macros then that might be a good way of offloading macro error handling.
# Objective
- On Safari mobile, calling `winit_window.set_cursor_grab(true)` fails as the API is not implemented (as there is no cursor on Safari mobile, the api doesn't make sense there). I don't know about other mobile browsers

## Solution
- Do not call the api to release cursor grab on window creation, as the cursor is not grabbed anyway at this point
# Objective
- Fix incorrect iterator usage in WriteStd430 impl for [T]
- The first item was being written twice. This is correct in the WriteStd140 impl for [T].
## Solution
- See the code.
Documentation added to:
- `App::add_sub_app` (
- `App::update` (mentions that sub apps are updated here)
### Future work
- An example for `add_sub_app` would be good, but I wasn't able to come up with a simple one.
- Since `SubApp` is private, maybe the concept of sub applications could be introduced in the `App` struct-level documentation.
This adds documentation for:
- The trait methods of `Reflect` and its subtraits
- The `partial_eq` and `apply` functions for `Map` et al.
- `DynamicList` and `DynamicMap`
- `TypeRegistry` and related types & traits
- `GetPath`, including an explanation of path string syntax
among other things.
Still to be documented are the various macros and `bevy_reflect::serde`.
# Objective
bevy_transform needed documentation and warn(missing_docs) as requested by #3492
## Solution
warn(missing_docs) was activated and documentation was added to cover the crate
Co-authored-by: Troels Jessen <kairyuka@gmail.com>
# Objective
- Fixes#3616
## Solution
- As described in the issue, documentation for `iter_manual` was copied from `iter_combinations` and did not reflect the behavior of the method. I've pulled some information from #2351 to create a more accurate description.
# Objective
- Removes warning about accidently inserting bundles with `EntityCommands::insert`, but since a component now needs to implement `Component` it is unnecessary.
Super tiny thing. Found this while reviewing #3479.
# Objective
- Simplify code
- Fix the link in the doc comment
## Solution
- Import a single item :)
Co-authored-by: Pascal Hertleif <pascal@technocreatives.com>
# Objective
CI should check for missing backticks in doc comments.
Fixes#3435
## Solution
`clippy` has a lint for this: `doc_markdown`. This enables that lint in the CI script.
Of course, enabling this lint in CI causes a bunch of lint errors, so I've gone through and fixed all of them. This was a huge edit that touched a ton of files, so I split the PR up by crate.
When all of the following are merged, the CI should pass and this can be merged.

This PR fixes lints in the `bevy_render` crate.
# Objective
This PR extends the `Events` documentation by:
- informing user about the possible race condition
- explicitly explaining the unusual double buffer implementation
Fixes#3305

# Objective
These traits are undocumented on `main`.
## Solution
Now they have docs! Included are examples for each trait and their corresponding `GetTypeField` trait. The docs also mention that `#[derive(Reflect)]` will automatically derive the correct subtrait on structs and tuple structs.
# Objective
In this PR I added the ability to opt-out graphical backends. Closes#3155.
## Solution
I turned backends into `Option` ~~and removed panicking sub app API to force users handle the error (was suggested by `@cart`)~~.
# Objective
The current 2d rendering is specialized to render sprites, we need a generic way to render 2d items, using meshes and materials like we have for 3d.
## Solution
I cloned a good part of `bevy_pbr` into `bevy_sprite/src/mesh2d`, removed lighting and pbr itself, adapted it to 2d rendering, added a `ColorMaterial`, and modified the sprite rendering to break batches around 2d meshes.
~~The PR is a bit crude; I tried to change as little as I could in both the parts copied from 3d and the current sprite rendering to make reviewing easier. In the future, I expect we could make the sprite rendering a normal 2d material, cleanly integrated with the rest.~~ _edit: see <https://github.com/bevyengine/bevy/pull/3460#issuecomment-1003605194>_
## Remaining work
- ~~don't require mesh normals~~ _out of scope_
- ~~add an example~~ _done_
- support 2d meshes & materials in the UI?
- bikeshed names (I didn't think hard about naming, please check if it's fine)
## Remaining questions
- ~~should we add a depth buffer to 2d now that there are 2d meshes?~~ _let's revisit that when we have an opaque render phase_
- ~~should we add MSAA support to the sprites, or remove it from the 2d meshes?~~ _I added MSAA to sprites since it's really needed for 2d meshes_
- ~~how to customize vertex attributes?~~ _#3120_
Co-authored-by: Carter Anderson <mcanders1@gmail.com>
# Objective
Updated the docs for bevy_ui as requested by #3492
## Solution
I have documented the parts I understand. anchors.rs is not in use and should be removed, thus I haven't documented that, and some of the more renderer-heavy code is beyond me and needs input from either cart or someone familiar with bevy rendering
Co-authored-by: Troels Jessen <kairyuka@gmail.com>
# Objective
- Using plain exponential depth slicing for perspective projection cameras results in unnecessarily many slices very close together close to the camera. If the camera is then moved close to a collection of point lights, they will likely exhaust the available uniform buffer space for the lists of which lights affect which clusters.
## Solution
- A simple solution to this is to use a different near plane value for the depth slicing and set it to where the first slice's far plane should be. The default value is 5 and works well. This results in the configured number of depth slices, maintains the exponential slicing beyond the initial slice, and no slices are too small such that they cause problems that are sensitive to the view position.
# Objective
- Fix the case mentioned in https://github.com/bevyengine/bevy/pull/2725#issuecomment-1007014024.
- On a machine with 4 cores, so 1 thread for assets, loading a gltf with only one textures hangs all asset loading
## Solution
- Do not use the task pool when there is only one texture to load

This PR fixes lints in the `bevy_ecs` crate.
# Objective
Part of #3492
- Complete inline documentation of `bevy_audio`
## Solution
- Added inline documentation to all public parts of `bevy_audio`
- Added a few inline examples at important places
- Some renaming for clarity (e.g. `AudioLoader` and generics)
- added `#![warn(missing_docs)]` and `#![forbid(unsafe_code)]` to `bevy_audio`
I also tried adding support for the other vorbis file endings `.oga` and `.spx` to the `AudioLoader` (see `file endings` at https://tools.ietf.org/html/rfc5334#section-10.3), but the `rodio` decoder does not seem to support those.

This PR fixes lints in the `bevy_text` crate.
# Objective
- Fixes#1920.
- Users often want to know how to get the values of removed components (#1655).
- Stand-alone `bevy_ecs` behavior is very unintuitive, as `World::clear_trackers()` must be manually called.
- Fixes#2999 by extending the existing test (thanks @hymm for pointing me to it) to be clearer and check for component removal as well.
## Solution
- Better docs!
- Better tests!
# Objective
- Load names of lights from gltf

# Objective
- Allow the user to specify the priority when configuring wgpu features/limits and by default use the maximum capabilities of the chosen adapter.
## Solution
- Add a `WgpuOptionsPriority` enum with `Compatibility`, `Functionality` and `WebGL2` options.
- Add a `priority: WgpuOptionsPriority` member to `WgpuOptions`.
- When initialising the renderer, if `WgpuOptions::priority == WgpuOptionsPriority::Functionality`, query the adapter for the available features and limits, use them when creating a device, and update `WgpuOptions` with those values. If `Compatibility` use the behaviour as before this PR. If `WebGL2` then use the WebGL2 downlevel limits as used when when building for wasm, for convenience of testing WebGL2 limits without having to build for wasm.
- Add an environment variable `WGPU_OPTIONS_PRIO` that takes `compatibility`, `functionality`, `webgl2`.
- Default to `WgpuOptionsPriority::Functionality`.
- Insert updated `WgpuOptions` into render app world as well. This is useful for applying the limits when rendering, such as limiting the directional light shadow map texture to 2048x2048 when using WebGL2 downlevel limits but not on wasm.
- Reduced `draw_state` logs from `debug` to `trace` and added `debug` level logs for the wgpu features and limits. Use `RUST_LOG=bevy_render=debug` to see the output.
Modifies the code emitted by `derive_label` to use fully-qualified type
names (e.g. `std::boxed::Box` instead of `Box`).
# Objective
- Using unqualified types here causes errors when the proc macro is used in contexts that locally define types with conflicting names (e.g. a local definition of `Box`).
## Solution
- Fully qualify standard types emitted by the proc macro code.
Updates the requirements on [nalgebra](https://github.com/dimforge/nalgebra) to permit the latest version.

<p><em>Sourced from <a href="https://github.com/dimforge/nalgebra/blob/dev/CHANGELOG.md">nalgebra's changelog</a>.</em></p>
<blockquote>
<h2>[0.30.0] (02 Jan. 2022)</h2>
<h3>Breaking changes</h3>
<ul>
<li>The <code>Dim</code> trait is now marked as unsafe.</li>
<li>The <code>Matrix::pow</code> and <code>Matrix::pow_mut</code> methods only allow positive integer exponents now. To compute negative
exponents, the user is free to invert the matrix before calling <code>pow</code> with the exponent’s absolute value.</li>
</ul>
<h3>Modified</h3>
<ul>
<li>Use more concise debug impls for matrices and geometric transformation types.</li>
<li>The singular values computed by the SVD are now sorted in increasing order by default. Use <code>SVD::new_unordered</code>
instead to reproduce the older behavior without the sorting overhead.</li>
<li>The <code>UnitDualQuaternion::sclerp</code> method will no longer panic when given two equal rotations.</li>
<li>The <code>Matrix::select_rows</code> and <code>Matrix::select_columns</code> methods no longer require the matrix components to implement
the trait <code>Zero</code>.</li>
<li>The <code>Matrix::pow</code> and <code>Matrix::pow_mut</code> methods will now also work with integer matrices.</li>
</ul>
<h3>Added</h3>
<ul>
<li>Added the conversion trait <code>From<Vec<T>></code> and method <code>from_vec_storage</code> for <code>RowDVector</code>.</li>
<li>Added implementation of <code>From</code> and <code>Into</code> for converting between <code>nalgebra</code> types and types from
<code>glam 0.18</code>. These can be enabled by enabling the <code>convert-glam018</code> cargo features.</li>
<li>Added the methods <code>Matrix::product</code>, <code>::row_product</code>, <code>::row_product_tr</code>, and <code>::column_product</code> to compute the
product of the components, rows, or columns, of a single matrix or vector.</li>
<li>The <code>Default</code> trait is now implemented for most geometric types: <code>Point</code>, <code>Isometry</code>, <code>Rotation</code>, <code>Similarity</code>,
<code>Transform</code>, <code>UnitComplex</code>, and <code>UnitQuaternion</code>.</li>
<li>Added the <code>Scale</code> geometric type for representing non-uniform scaling.</li>
<li>Added <code>Cholesky::new_with_substitute</code> that will replace diagonal elements by a given constant whenever <code>Cholesky</code>
meets a non-definite-positiveness.</li>
<li>Re-added the conversion from a vector/matrix slice to a static array.</li>
<li>Added the <code>cuda</code> feature that enables the support of <a href="https://github.com/Rust-GPU/Rust-CUDA">rust-cuda</a> for using
<code>nalgebra</code> features with CUDA kernels written in Rust.</li>
<li>Added special-cases implementations for the 2x2 and 3x3 SVDs for better accuracy and performances.</li>
<li>Added the methods <code>Matrix::polar</code>, <code>Matrix::try_polar</code>, and <code>SVD::to_polar</code> to compute the polar decomposition of
a matrix, based on its SVD.</li>
<li><code>nalgebra-sparse</code>: provide constructors for unsorted but otherwise valid data using the CSR format.</li>
<li><code>nalgebra-sparse</code>: added reading MatrixMarked data files to a sparse <code>CooMatrix</code>.</li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Fixed a potential unsoundness with <code>matrix.get(i)</code> and <code>matrix.get_mut(i)</code> where <code>i</code> is an <code>usize</code>, and <code>matrix</code>
is a matrix slice with non-default strides.</li>
<li>Fixed potential unsoundness with <code>vector.perp</code> where <code>vector</code> isn’t actually a 2D vector as expected.</li>
<li>Fixed linkage issue with <code>nalgebra-lapack</code>: the user of <code>nalgebra-lapack</code> no longer have to add
<code>extern crate lapack-src</code> to their <code>main.rs</code>.</li>
<li>Fixed the <code>no-std</code> build of <code>nalgebra-glm</code>.</li>
<li>Fix the <code>pow</code> and <code>pow_mut</code> functions (the result was incorrect for some exponent values).</li>
</ul>
<h2>[0.29.0]</h2>
<h3>Breaking changes</h3>
<ul>
<li>We updated to the version 0.6 of <code>simba</code>. This means that the trait bounds <code>T: na::RealField</code>, <code>na::ComplexField</code>,
<code>na::SimdRealField</code>, <code>na:SimdComplexField</code> no imply that <code>T: Copy</code> (they only imply that <code>T: Clone</code>). This may affect</li>

# Objective
- Add support for loading lights from glTF 2.0 files
## Solution
- This adds support for the KHR_punctual_lights extension which supports point, directional, and spot lights, though we don't yet support spot lights.
- Inserting light bundles when creating scenes required registering some more light bundle component types.
This PR is part of the issue #3492.
# Objective
- Clean up dead code in `bevy_core`.
- Add and update the `bevy_core` documentation to achieve a 100% documentation coverage.
- Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.
# Solution
- Remove unused `Bytes`, `FromBytes`, `Labels`, and `EntityLabels` types and associated systems.
- Made several types private that really only have use as internal types, mostly pertaining to fixed timestep execution.
- Add and update the bevy_core documentation.
- Add the #![warn(missing_docs)] lint.
# Open Questions
Should more of the internal states of `FixedTimestep` be public? Seems mostly to be an implementation detail unless someone really needs that fixed timestep state.
# Objective
- Nightly checks where disabled because of a bug in Rust
- Dependency checks are failing because of a new duplicate
## Solution
- Now that https://github.com/rust-lang/rust/pull/92175 has been merged, re-enable nightly checks
- Add the new duplicate dependency to the known list
- Removed `Inflector` dependency as it's not used anymore
Co-authored-by: François <8672791+mockersf@users.noreply.github.com>
# Objective
Docs updates.
## Solution
- Detail what `OrthographicCameraBundle::new_2d()` creates.
- Fix a few renamed parameters in comments of `TrackedRenderPass`.
- Add missing comments for viewport and debug markers.

This PR is part of the issue #3492.
# Objective
- Add and update the bevy_dylib documentation to achieve a 100% documentation coverage.
- Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.
# Solution
- Add and update the bevy_dylib documentation.
- Add the #![warn(missing_docs)] lint.
# Objective
This contributes documentation that should cover the entirety of bevy_internal as requested in #3492
## Solution
warn(missing_docs) has been activated and documentation has been added to missing parts so that no warnings appear from this setting
# Objective
- After updating #2988, all the examples started crashing with
```
thread 'main' panicked at 'Plugin "bevy_render::render_component::ExtractComponentPlugin<bevy_asset::handle::Handle<bevy_pbr::pbr_material::StandardMaterial>>" was already added', crates/bevy_app/src/app.rs:831:33
```
## Solution
Plugin was added twice:
directly:
1d0d8a3397/crates/bevy_pbr/src/lib.rs (L73)
and through `MaterialPlugin`:
1d0d8a3397/crates/bevy_pbr/src/lib.rs (L72)1d0d8a3397/crates/bevy_pbr/src/material.rs (L183)
I removed the extra plugin

# Objective
Remove the `StorageType` parameter from `ComponentDescriptor::new_resource` as discussed in #3361.
- fixes#3361
## Solution
- Parameter removed.
- Basic docs added.
## Note
Left a [comment](https://github.com/bevyengine/bevy/issues/3361#issuecomment-996433346) about `SparseStorage` being the more reasonable choice.

This PR fixes lints in the `bevy_app` crate.
# Objective
- `Msaa` was disabled in webgl due to a bug in wgpu
- Bug has been fixed (https://github.com/gfx-rs/wgpu/pull/2307) and backported (https://github.com/gfx-rs/wgpu/pull/2327), and updates for [`wgpu-core`](https://crates.io/crates/wgpu-core/0.12.1) and [`wgpu-hal`](https://crates.io/crates/wgpu-hal/0.12.1) have been released
## Solution
- Remove custom config for `Msaa` in webgl
- I also changed two options that were using the arch instead of the `webgl` feature. it shouldn't change much for webgl, but could help if someone wants to target wasm but not webgl2

# Objective
Resolves#3277
Currenty if we try to serialize a scene that contains a `Duration` (which is very common, since `Timer` contains one), we get an error saying:
> Type 'core::time::Duration' does not support ReflectValue serialization
## Solution
Let `Duration` implement `SerializeValue`.

Dynamic types (`DynamicStruct`, `DynamicTupleStruct`, `DynamicTuple`, `DynamicList` and `DynamicMap`) are used when deserializing scenes, but currently they can only be applied to existing concrete types. This leads to issues when trying to spawn non trivial deserialized scene.
For components, the issue is avoided by requiring that reflected components implement ~~`FromResources`~~ `FromWorld` (or `Default`). When spawning, a new concrete type is created that way, and the dynamic type is applied to it. Unfortunately, some components don't have any valid implementation of these traits.
In addition, any `Vec` or `HashMap` inside a component will panic when a dynamic type is pushed into it (for instance, `Text` panics when adding a text section).
To solve this issue, this PR adds the `FromReflect` trait that creates a concrete type from a dynamic type that represent it, derives the trait alongside the `Reflect` trait, drops the ~~`FromResources`~~ `FromWorld` requirement on reflected components, ~~and enables reflection for UI and Text bundles~~. It also adds the requirement that fields ignored with `#[reflect(ignore)]` implement `Default`, since we need to initialize them somehow.

# Objective

## Solution
- Remove `mut` when possible

This adds "high level" `Material` and `SpecializedMaterial` traits, which can be used with a `MaterialPlugin<T: SpecializedMaterial>`. `MaterialPlugin` automatically registers the appropriate resources, draw functions, and queue systems. The `Material` trait is simpler, and should cover most use cases. `SpecializedMaterial` is like `Material`, but it also requires defining a "specialization key" (see #3031). `Material` has a trivial blanket impl of `SpecializedMaterial`, which allows us to use the same types + functions for both.
This makes defining custom 3d materials much simpler (see the `shader_material` example diff) and ensures consistent behavior across all 3d materials (both built in and custom). I ported the built in `StandardMaterial` to `MaterialPlugin`. There is also a new `MaterialMeshBundle<T: SpecializedMaterial>`, which `PbrBundle` aliases to.
# Objective
- I want to port `bevy_egui` to Bevy main and only reuse re-exports from Bevy

- Add exports for `BufferBinding` and `BufferDescriptor`

# Objective
Fixes#3422
## Solution
Adds the existing `Visibility` component to UI bundles and checks for it in the extract phase of the render app.
The `ComputedVisibility` component was not added. I don't think the UI camera needs frustum culling, but having `RenderLayers` work may be desirable. However I think we would need to change `check_visibility()` to differentiate between 2d, 3d and UI entities.
# Objective
Fix#2406
Scene parenting was not done completely, leaving the hierarchy maintenance to the standard system. As scene spawning happens in stage `PreUpdate` and hierarchy maintenance in stage `PostUpdate`, this left the scene in an invalid state parent wise for part of a frame
## Solution
Also add/update the `Children` component when spawning the scene.
I kept the `Children` component as a `SmallVec`, it could be moved to an `HashSet` to guarantee uniqueness

# Objective
- Our crevice is still called "crevice", which we can't use for a release
- Users would need to use our "crevice" directly to be able to use the derive macro
## Solution
- Rename crevice to bevy_crevice, and crevice-derive to bevy-crevice-derive
- Re-export it from bevy_render, and use it from bevy_render everywhere
- Fix derive macro to work either from bevy_render, from bevy_crevice, or from bevy
## Remaining
- It is currently re-exported as `bevy::render::bevy_crevice`, is it the path we want?
- After a brief suggestion to Cart, I changed the version to follow Bevy version instead of crevice, do we want that?
- Crevice README.md need to be updated
- in the `Cargo.toml`, there are a few things to change. How do we want to change them? How do we keep attributions to original Crevice?

WIthout the feature, `gilrs` uses `stdweb` instead of `wasm-bindgen` which isn't compatible with the rest of bevy.
Unfortunately, the `stdweb` dependency is still in the dependency tree, it just isn't used (https://gitlab.com/gilrs-project/gilrs/-/issues/101). This will be fixed in `gilrs 0.9` when it releases.
# Objective
Instead of panicking when the `indices` field of a mesh is `None`, actually manage it.
This is just a question of keeping track of the vertex buffer size.
## Notes
* Relying on this change to improve performance on [bevy_debug_lines using the new renderer](https://github.com/Toqozz/bevy_debug_lines/pull/10)
* I'm still new to rendering, my only expertise with wgpu is the learn-wgpu tutorial, likely I'm overlooking something.
### Problem
- shader processing errors are not displayed
- during hot reloading when encountering a shader with errors, the whole app crashes
### Solution
- log `error!`s for shader processing errors
- when `cfg(debug_assertions)` is enabled (i.e. you're running in `debug` mode), parse shaders before passing them to wgpu. This lets us handle errors early.
# Objective
- 3d examples fail to run in webgl2 because of unsupported texture formats or texture too large
## Solution
- switch to supported formats if a feature is enabled. I choose a feature instead of a build target to not conflict with a potential webgpu support
Very inspired by 6813b2edc5, and need #3290 to work.
I named the feature `webgl2`, but it's only needed if one want to use PBR in webgl2. Examples using only 2D already work.

# Objective
- fixes#3397
## Solution
- Uses EventWriter instead of ResMut<Event> in gilrs_system.rs.
I also renamed the argument from `event` to `events` for consistency. All other instances I could find in the engine of EventWriter use a plural argument name. Happy to undo or modify this change if desired.
# Objective
Add missing methods to `TrackedRenderPass`
- `set_push_constants`
- `set_viewport`
- `insert_debug_marker`
- `push_debug_group`
- `pop_debug_group`
- `set_blend_constant`
https://docs.rs/wgpu/0.12.0/wgpu/struct.RenderPass.html
I need `set_push_constants` but started adding the others as I noticed they were also missing. The `draw indirect` family of methods are still missing as are the `timestamp query` methods.
# Objective
The window's cursor should be settable without having to implement a custom cursor icon solution. This will especially be helpful when creating user-interfaces that might like to use the cursor to denote some meaning (e.g., _clickable_, _resizable_, etc.).
## Solution
Added a `CursorIcon` enum that maps one-to-one to winit's `CursorIcon` enum, as well as a method to set/get it for the given `Window`.
# Objective
Fixes: #3368
Issue was caused by screen size being: `(0, 0)`.
## Solution
Don't update clusters if the screen size is zero. A better solution might be to not render when minimized, but this works in the meantime.

# Objective
- Only bevy_render should depend directly on wgpu

# Objective
- Storages are used to store the ECS data.
- They're undocumented.

# Objective
This PR implements the `overflow` style property in `bevy_ui`. When set to `Overflow::Hidden`, the children of that node are clipped so that overflowing parts are not rendered. This is an important building block for UI widgets.
## Solution
Clipping is done on the CPU so that it does not break batching.
The clip regions update was implemented as a separate system for clarity, but it could be merged with the other UI systems to avoid doing an additional tree traversal. (I don't think it's important until we fix the layout performance issues though).
A scrolling list was added to the `ui_pipelined` example to showcase `Overflow::Hidden`. For the sake of simplicity, it can only be scrolled with a mouse.
# Objective
Fixes#3352Fixes#3208
## Solution
- Update wgpu to 0.12
- Update naga to 0.8
- Resolve compilation errors
- Remove [[block]] from WGSL shaders (because it is depracated and now wgpu cant parse it)
- Replace `elseif` with `else if` in pbr.wgsl
Fixes#2566Fixes#3005

# Objective
I thought I'd have a go a trying to fix#2597.
Hopefully fixes#2597.
## Solution
I reused the memory pointed to by the value parameter, that is already required by `insert` to not be dropped, to contain the extracted value while dropping it.
# Objective
- The multiple windows example which was viciously murdered in #3175.
- cart asked me to
## Solution
- Rework the example to work on pipelined-rendering, based on the work from #2898
These derives seem to be leftover vestiges of the old renderer.
At least removing them doesn't seem to harm anything.
edit: thanks `@forbjok` on discord for pointing this out.
# Objective
- There are a few warnings when building Bevy docs for dead links
- CI seems to not catch those warnings when it should
## Solution
- Enable doc CI on all Bevy workspace
- Fix warnings
- Also noticed plugin GilrsPlugin was not added anymore when feature was enabled
First commit to check that CI would actually fail with it: https://github.com/bevyengine/bevy/runs/4532652688?check_suite_focus=true

# Objective And Solution
Add `set_scissor_rect` from wgpu-rs to the `TrackedRenderPass`. wgpu documentation can be found here:
https://docs.rs/wgpu/latest/wgpu/struct.RenderPass.html#method.set_scissor_rect
The reason for adding this is to cull fragments that are outside of the given rect. For my purposes this is extremely useful for UI.
# Objective
Previously, the gilrs system had no explicit relationship to the input
systems. This could potentially cause it to be scheduled after the
input systems, leading to a one-frame lag in gamepad inputs.
This was a regression introduced in #1606 which removed the `PreEvent` stage
## Solution
This adds an explicit `before` relationship to the gilrs plugin,
ensuring that raw gamepad events will be processed on the same frame
that they are generated.
Currently the `ClearPassNode` is not exported, due to an additional `use ...;` in the core pipeline's `lib.rs`. This seems unintentional, as there already is a public glob import in the file.
This just removes the explicit use. If it actually was intentional to keep the node internal, let me know.
# Objective
`KeyCode::*Win` and `KeyCode::*Alt` might be confusing for some Mac users.
## Solution
Added some small documentation to clarify the mappings for those developing on a Mac.
## Additional Context
Related issue: #3240
# Objective
This PR fixes a crash when winit is enabled when there is a camera in the world. Part of #3155
## Solution
In this PR, I removed two unwraps and added an example for regression testing.
# Objective
PBR lighting was broken in the new renderer when using orthographic projections due to the way the depth slicing works for the clusters. Fix it.
## Solution
- The default orthographic projection near plane is 0.0. The perspective projection depth slicing does a division by the near plane which gives a floating point NaN and the clustering all breaks down.
- Orthographic projections have a linear depth mapping, so it made intuitive sense to me to do depth slicing with a linear mapping too. The alternative I saw was to try to handle the near plane being at 0.0 and using the exponential depth slicing, but that felt like a hack that didn't make sense.
- As such, I have added code that detects whether the projection is orthographic based on `projection[3][3] == 1.0` and then implemented the orthographic mapping case throughout (when computing cluster AABBs, and when mapping a view space position (or light) to a cluster id in both the rust and shader code).

This makes the [New Bevy Renderer](#2535) the default (and only) renderer. The new renderer isn't _quite_ ready for the final release yet, but I want as many people as possible to start testing it so we can identify bugs and address feedback prior to release.
The examples are all ported over and operational with a few exceptions:
* I removed a good portion of the examples in the `shader` folder. We still have some work to do in order to make these examples possible / ergonomic / worthwhile: #3120 and "high level shader material plugins" are the big ones. This is a temporary measure.
* Temporarily removed the multiple_windows example: doing this properly in the new renderer will require the upcoming "render targets" changes. Same goes for the render_to_texture example.
* Removed z_sort_debug: entity visibility sort info is no longer available in app logic. we could do this on the "render app" side, but i dont consider it a priority.
# Objective
Fixes#3247
## Solution
- Added docs to `Axis<T>`. This one can be extended @alice-i-cecile
- Added unit tests
- Added `min` and `max` values to the struct. @alice-i-cecile Do we need to these variables?
- Limited `set` method usage with `min` and `max` values

# Objective
Port bevy_ui to pipelined-rendering (see #2535 )
## Solution
I did some changes during the port:
- [X] separate color from the texture asset (as suggested [here](https://discord.com/channels/691052431525675048/743663924229963868/874353914525413406))
- [X] ~give the vertex shader a per-instance buffer instead of per-vertex buffer~ (incompatible with batching)
Remaining features to implement to reach parity with the old renderer:
- [x] textures
- [X] TextBundle
I'd also like to add these features, but they need some design discussion:
- [x] batching
- [ ] separate opaque and transparent phases
- [ ] multiple windows
- [ ] texture atlases
- [ ] (maybe) clipping
# Objective
Make it easier to build and use an asset path with `format!()`. This can be useful for accessing assets in a loop.
Enabled by this PR:
```rust
let monkey_handle = asset_server.get_handle(&format!("models/monkey/Monkey.gltf#Mesh0/Primitive0"));
let monkey_handle = asset_server.get_handle(format!("models/monkey/Monkey.gltf#Mesh0/Primitive0"));
```
Before this PR:
```rust
let monkey_handle = asset_server.get_handle(format!("models/monkey/Monkey.gltf#Mesh0/Primitive0").as_str());
```
It's just a tiny improvement in ergonomics, but i ran into it and was wondering why the function does not accept a `String` and Bevy is all about simplicity/ergonomics, right? 😄😉
## Solution
Implement `Into<HandleId>` for `String` and `&String`.
# Objective
- there are a few new versions for `ron`, `winit`, `ndk`, `raw-window-handle`
- `cargo-deny` is failing due to new security issues / duplicated dependencies
## Solution
- Update our dependencies
- Note all new security issues, with which of Bevy direct dependency it comes from
- Update duplicate crate list, with which of Bevy direct dependency it comes from
`notify` is not updated here as it's in #2993
Fills in some gaps we had in our Bevy ECS tracing spans:
* Exclusive systems
* System Commands (for `apply_buffers = true` cases)
* System archetype updates
* Parallel system execution prep
Applogies, had to recreate this pr because of branching issue.
Old PR: https://github.com/bevyengine/bevy/pull/3033

Allowing a user to create a transparent window
## Solution
I've allowed the transparent bool to be passed to the winit window builder
# Objective
- Checks for NaN in computed NDC space coordinates, fixing unexpected NaN in a fallible (`Option<T>`) function.
## Solution
- Adds a NaN check, in addition to the existing NDC bounds checks.
- This is a helper function, and should have no performance impact to the engine itself.
- This will help prevent hard-to-trace NaN propagation in user code, by returning `None` instead of `Some(NaN)`.
Depends on https://github.com/bevyengine/bevy/pull/3269 for CI error fix.

## Solution
- Fixed clippy lints following suggestions
- I ignored clippy in old renderer because there was many and it will be removed soon
A sample implementation of how to have `iter()` work on mutable queries without breaking aliasing rules.
# Objective
- Fixes#753
## Solution
- Added a ReadOnlyFetch to WorldQuery that is the `&T` version of `&mut T` that is used to specify the return type for read only operations like `iter()`.
- ~~As the comment suggests specifying the bound doesn't work due to restrictions on defining recursive implementations (like `Or`). However bounds on the functions are fine~~ Never mind I misread how `Or` was constructed, bounds now exist.
- Note that the only mutable one has a new `Fetch` for readonly as the `State` has to be the same for any of this to work

This pull request aims to solve the issue of a lack of documentation in the enum WindowMode
# Objective
- Fixes#3136
## Solution
- Added a few lines of documentation that should document what the enum does better
# Problem
Let's say I am writting a simple bevy plugin, and I want to depend on `bevy_ecs` crate instead of depending on the full `bevy`.
So I write the following:
*Cargo.toml*:
```toml
[dependencies]
bevy_ecs = { git = "https://github.com/bevyengine/bevy.git", rev = "94db0176fecfac7e7e9763f2dc7458a54c105886" }
```
*lib.rs*:
```rust
use bevy_ecs::prelude::*;
#[derive(Debug, Default, Component)
pub struct MyFancyComponent;
```
So far, so good. Everything works. But let's say I want to write some examples for using my plugin. And for theses I'd like to use the `bevy` crate, so that I can write complete examples (rendering stuff, etc.) that are simple and look like what the consumer of my plugin will do (`use bevy::prelude::*` and `DefaultPlugins`)
So I amend my *Cargo.toml*:
```toml
[dependencies]
bevy_ecs = { git = "https://github.com/bevyengine/bevy.git", rev = "94db0176fecfac7e7e9763f2dc7458a54c105886" }
[dev-dependencies]
bevy = { git = "https://github.com/bevyengine/bevy.git", rev = "94db0176fecfac7e7e9763f2dc7458a54c105886", default-features = false }
```
And that leads to a complilation error
```
error[E0433]: failed to resolve: use of undeclared crate or module `bevy`
```
Basically, because `bevy` is in the `dev-dependencies`, the macro (of the production code) decides to use the `bevy::ecs` path instead of `bevy_ecs`. But `bevy` is not available there.
## Solution
This PR fixes the problem. I amend the macro utility responsible of finding the path of a module.
If we try to find a path, we first test if this correspond to a crate that the user directly depend on. (Like, if we search for `bevy_ecs`, we first check if there is a `bevy_ecs` dependency). If yes, we can depend on that directly. Otherwise, we proceed with the existing logic (testing `bevy` and `bevy_internal`)
## Shader Imports
This adds "whole file" shader imports. These come in two flavors:
### Asset Path Imports
```rust
// /assets/shaders/custom.wgsl
#import "shaders/custom_material.wgsl"
[[stage(fragment)]]
fn fragment() -> [[location(0)]] vec4<f32> {
return get_color();
}
```
```rust
// /assets/shaders/custom_material.wgsl
[[block]]
struct CustomMaterial {
color: vec4<f32>;
};
[[group(1), binding(0)]]
var<uniform> material: CustomMaterial;
```
### Custom Path Imports
Enables defining custom import paths. These are intended to be used by crates to export shader functionality:
```rust
// bevy_pbr2/src/render/pbr.wgsl
#import bevy_pbr::mesh_view_bind_group
#import bevy_pbr::mesh_bind_group
[[block]]
struct StandardMaterial {
base_color: vec4<f32>;
emissive: vec4<f32>;
perceptual_roughness: f32;
metallic: f32;
reflectance: f32;
flags: u32;
};
/* rest of PBR fragment shader here */
```
```rust
impl Plugin for MeshRenderPlugin {
fn build(&self, app: &mut bevy_app::App) {
let mut shaders = app.world.get_resource_mut::<Assets<Shader>>().unwrap();
shaders.set_untracked(
MESH_BIND_GROUP_HANDLE,
Shader::from_wgsl(include_str!("mesh_bind_group.wgsl"))
.with_import_path("bevy_pbr::mesh_bind_group"),
);
shaders.set_untracked(
MESH_VIEW_BIND_GROUP_HANDLE,
Shader::from_wgsl(include_str!("mesh_view_bind_group.wgsl"))
.with_import_path("bevy_pbr::mesh_view_bind_group"),
);
```
By convention these should use rust-style module paths that start with the crate name. Ultimately we might enforce this convention.
Note that this feature implements _run time_ import resolution. Ultimately we should move the import logic into an asset preprocessor once Bevy gets support for that.
## Decouple Mesh Logic from PBR Logic via MeshRenderPlugin
This breaks out mesh rendering code from PBR material code, which improves the legibility of the code, decouples mesh logic from PBR logic, and opens the door for a future `MaterialPlugin<T: Material>` that handles all of the pipeline setup for arbitrary shader materials.
## Removed `RenderAsset<Shader>` in favor of extracting shaders into RenderPipelineCache
This simplifies the shader import implementation and removes the need to pass around `RenderAssets<Shader>`.
## RenderCommands are now fallible
This allows us to cleanly handle pipelines+shaders not being ready yet. We can abort a render command early in these cases, preventing bevy from trying to bind group / do draw calls for pipelines that couldn't be bound. This could also be used in the future for things like "components not existing on entities yet".
# Next Steps
* Investigate using Naga for "partial typed imports" (ex: `#import bevy_pbr::material::StandardMaterial`, which would import only the StandardMaterial struct)
* Implement `MaterialPlugin<T: Material>` for low-boilerplate custom material shaders
* Move shader import logic into the asset preprocessor once bevy gets support for that.

bevy_ecs has several compile_fail tests that assert lifetime safety. In the past, these tests have been green for the wrong reasons (see e.g. #2984). This PR makes sure, that they will fail if the compiler error changes.
## Solution
Use [trybuild](https://crates.io/crates/trybuild) to assert the compiler errors.
The UI tests are in a separate crate that is not part of the Bevy workspace. This is to ensure that they do not break Bevy's crater builds. The tests get executed by the CI workflow on the stable toolchain.

Document that `AssetServer::load()` is asynchronous.
## Solution
Document that `AssetServer::load()` is asynchronous, and that the asset
will not be immediately available once the call returns. Instead,
explain that the user must call `AssetServer::get_load_state()` to
monitor the loading state of an asset.
# Objective
- `bevy_ecs` exposes as an optional feature `bevy_reflect`. Disabling it doesn't compile.
- `bevy_asset` exposes as an optional feature `filesystem_watcher`. Disabling it doesn't compile. It is also not possible to disable this feature from Bevy
## Solution
- Fix compilation errors when disabling the default features. Make it possible to disable the feature `filesystem_watcher` from Bevy
# Objective
- Update vendor crevice to have the latest update from crevice 0.8.0
- Using https://github.com/ElectronicRU/crevice/tree/arrays which has the changes to make arrays work
## Solution
- Also updated glam and hexasphere to only have one version of glam
- From the original PR, using crevice to write GLSL code containing arrays would probably not work but it's not something used by Bevy
# Objective
Clarify the fact that setting the `RUST_LOG` environment variable
overrides any setting from the `LogSettings` resource.
## Solution
Update docstring comment for `LogSettings`.
- Requires #2997
- Removes `wasm_audio` feature as discussed in #2397
- Closes only task in #2479
Open questions:
Should we enable wasm audio by default or only when building for wasm using `cfg`?
Maybe there should be a global wasm feature for bevy?
# Objective
Fixes#2823.
## Solution
This PR adds notes to the `HashMap` and `HashSet` docs explaining why `HashMap::new()` (resp. `HashSet::new()`) is not available, and guiding the user toward using the `Default` implementation for an empty collection.
# Objective
- Improve error descriptions and help understand how to fix them
- I noticed one today that could be expanded, it seemed like a good starting point
## Solution
- Start something like https://github.com/rust-lang/rust/tree/master/compiler/rustc_error_codes/src/error_codes
- Remove sentence about Rust mutability rules which is not very helpful in the error message
I decided to start the error code with B for Bevy so that they're not confused with error code from rust (which starts with E)
Longer term, there are a few more evolutions that can continue this:
- the code samples should be compiled check, and even executed for some of them to check they have the correct error code in a panic
- the error could be build on a page in the website like https://doc.rust-lang.org/error-index.html
- most panic should have their own error code
Mention the fact that the UI layout system is based on the CSS layout
model through a docstring comment on the `Style` type.
# Objective
Explain to new users that the Bevy UI uses the CSS layout model, to lower the barrier to entry given the fact documentation (book and code) is fairly limited on the topic.
## Solution
Fix as discussed with @alice-i-cecile on #2918.
# Objective
Set initial position of the window, so I can start it at the left side of the view automatically, used with `cargo watch`
## Solution
add window position to WindowDescriptor
# Objective
Make possible to use wgpu gles backend on in the browser (wasm32 + WebGL2).
## Solution
It is built on top of old @cart patch initializing windows before wgpu. Also:
- initializes wgpu with `Backends::GL` and proper `wgpu::Limits` on wasm32
- changes default texture format to `wgpu::TextureFormat::Rgba8UnormSrgb`
Co-authored-by: Mariusz Kryński <mrk@sed.pl>
# Objective
- Fixes#2919
- Initial pixel was hard coded and not dependent on texture format
- Replace #2920 as I noticed this needed to be done also on pipeline rendering branch
## Solution
- Replace the hard coded pixel with one using the texture pixel size
Objective
During work on #3009 I've found that not all jobs use actions-rs, and therefore, an previous version of Rust is used for them. So while compilation and other stuff can pass, checking markup and Android build may fail with compilation errors.
Solution
This PR adds `action-rs` for any job running cargo, and updates the edition to 2021.
# Objective
The current TODO comment is out of date
## Solution
I switched up the comment
Co-authored-by: William Batista <45850508+billyb2@users.noreply.github.com>
# Objective
- Bevy has several `compile_fail` test
- #2254 added `#[derive(Component)]`
- Those tests now fail for a different reason.
- This was not caught as these test still "successfully" failed to compile.
## Solution
- Add `#[derive(Component)]` to the doctest
- Also changed their cfg attribute from `doc` to `doctest`, so that these tests don't appear when running `cargo doc` with `--document-private-items`
# Objective
- Fixes#2501
- Builds up on #2639 taking https://github.com/bevyengine/bevy/pull/2639#issuecomment-898701047 into account
## Solution
- keep the physical cursor position in `Window`, and expose it.
- still convert to logical position in event, and when getting `cursor_position`
Co-authored-by: Ahmed Charles <acharles@outlook.com>
# Objective
The update to wgpu 0.11 broke CI for android. This was due to a confusion between `bevy::render::ShaderStage` and `wgpu::ShaderStage`.
## Solution
Revert the incorrect change
#2605 changed the lifetime annotations on `get_component` introducing unsoundness as you could keep the returned borrow even after using the query.
Example unsoundness:
```rust
use bevy::prelude::*;
fn main() {
App::new()
.add_startup_system(startup)
.add_system(unsound)
.run();
}
#[derive(Debug, Component, PartialEq, Eq)]
struct Foo(Vec<u32>);
fn startup(mut c: Commands) {
let e = c.spawn().insert(Foo(vec![10])).id();
c.insert_resource(e);
}
fn unsound(mut q: Query<&mut Foo>, res: Res<Entity>) {
let foo = q.get_component::<Foo>(*res).unwrap();
let mut foo2 = q.iter_mut().next().unwrap();
let first_elem = &foo.0[0];
for _ in 0..16 {
foo2.0.push(12);
}
dbg!(*first_elem);
}
```
output:
`[src/main.rs:26] *first_elem = 0`
Add the entity ID and generation to the expect() message of two
world accessors, to make it easier to debug use-after-free issues.
Coupled with e.g. bevy-inspector-egui which also displays the entity ID,
this makes it much easier to identify what entity is being misused.
# Objective
Make it easier to identity an entity being accessed after being deleted.
## Solution
Augment the error message of some `expect()` call with the entity ID and
generation. Combined with some external tool like `bevy-inspector-egui`, which
also displays the entity ID, this increases the chances to be able to identify
the entity, and therefore find the error that led to a use-after-despawn.
Upgrades both the old and new renderer to wgpu 0.11 (and naga 0.7). This builds on @zicklag's work here #2556.

# Objective
- Remove duplicate `Events::update` call in `gilrs_event_system` (fixes#2893)
- See #2893 for context
- While there, make the systems no longer exclusive, as that is not required of them
## Solution
- Do the change
r? @alice-i-cecile
This PR adds a ControlNode which marks an entity as "transparent" to the UI layout system, meaning the children of this entity will be treated as the children of this entity s parent by the layout system(s).
# Objective
- Fixes#2904 (see for context)
## Solution
- Simply hoist span creation out of the threaded task
- Confirmed to solve the issue locally
Now all events have the full span parent tree up through `bevy_ecs::schedule::stage` all the way to `bevy_app::app::bevy_app` (and its parents in bevy-consumer code, if any).
# Objective
- Avoid usages of `format!` that ~immediately get passed to another `format!`. This avoids a temporary allocation and is just generally cleaner.
## Solution
- `bevy_derive::shader_defs` does a `format!("{}", val.to_string())`, which is better written as just `format!("{}", val)`
- `bevy_diagnostic::log_diagnostics_plugin` does a `format!("{:>}", format!(...))`, which is better written as `format!("{:>}", format_args!(...))`
- `bevy_ecs::schedule` does `tracing::info!(..., name = &*format!("{:?}", val))`, which is better written with the tracing shorthand `tracing::info!(..., name = ?val)`
- `bevy_reflect::reflect` does `f.write_str(&format!(...))`, which is better written as `write!(f, ...)` (this could also be written using `f.debug_tuple`, but I opted to maintain alt debug behavior)
- `bevy_reflect::serde::{ser, de}` do `serde::Error::custom(format!(...))`, which is better written as `Error::custom(format_args!(...))`, as `Error::custom` takes `impl Display` and just immediately calls `format!` again
This implements the most minimal variant of #1843 - a derive for marker trait. This is a prerequisite to more complicated features like statically defined storage type or opt-out component reflection.
In order to make component struct's purpose explicit and avoid misuse, it must be annotated with `#[derive(Component)]` (manual impl is discouraged for compatibility). Right now this is just a marker trait, but in the future it might be expanded. Making this change early allows us to make further changes later without breaking backward compatibility for derive macro users.
This already prevents a lot of issues, like using bundles in `insert` calls. Primitive types are no longer valid components as well. This can be easily worked around by adding newtype wrappers and deriving `Component` for them.
One funny example of prevented bad code (from our own tests) is when an newtype struct or enum variant is used. Previously, it was possible to write `insert(Newtype)` instead of `insert(Newtype(value))`. That code compiled, because function pointers (in this case newtype struct constructor) implement `Send + Sync + 'static`, so we allowed them to be used as components. This is no longer the case and such invalid code will trigger a compile error.

# Objective
Fixes these issues:
- `WorldId`s currently aren't necessarily unique
- I want to guarantee that they're unique to safeguard my librarified version of https://github.com/bevyengine/bevy/discussions/2805
- There probably hasn't been a collision yet, but they could technically collide
- `SystemId` isn't used for anything
- It's no longer used now that `Locals` are stored within the `System`.
- `bevy_ecs` depends on rand
## Solution
- Instead of randomly generating `WorldId`s, just use an incrementing atomic counter, panicing on overflow.
- Remove `SystemId`
- We do need to allow Locals for exclusive systems at some point, but exclusive systems couldn't access their own `SystemId` anyway.
- Now that these don't depend on rand, move it to a dev-dependency
## Todo
Determine if `WorldId` should be `u32` based instead
If you need to build a texture atlas from an already created texture that is not match a grid, you need to use new_empty and add_texture to create it. However it is not straight forward to get the index to be used with TextureAtlasSprite. add_texture should be changed to return the index to the texture.
Currently you can do something like this:
```rs
let texture = asset_server.load::<Texture>::("texture.png");
let texture_atlas = TextureAtlas::new_empty(texture, Vec2::new(40.0, 40.0));
texture_atlas.add_texture(Rect {
min: Vec2::new(20.0, 20.0),
max: Vec2::new(40.0, 40.0),
});
let index = (texture_atlas.len() - 1) as u32;
let texture_atlas_sprite = TextureAtlasSprite {
index,
Default::default()
};
```
But this is more clear
```rs
let index = texture_atlas.add_texture(Rect {
min: Vec2::new(20.0, 20.0),
max: Vec2::new(40.0, 40.0),
});
```

# Objective
Noticed a comment saying changed detection should be enabled for hierarchy maintenance once stable
Fixes#891
## Solution
Added `Changed<Parent>` filter on the query
Changed out unwraps to use if let syntax instead. Returning false when None.
Also modified an existing test to encompass these methods
This PR fixes#2828
This changes how render logic is composed to make it much more modular. Previously, all extraction logic was centralized for a given "type" of rendered thing. For example, we extracted meshes into a vector of ExtractedMesh, which contained the mesh and material asset handles, the transform, etc. We looked up bindings for "drawn things" using their index in the `Vec<ExtractedMesh>`. This worked fine for built in rendering, but made it hard to reuse logic for "custom" rendering. It also prevented us from reusing things like "extracted transforms" across contexts.
To make rendering more modular, I made a number of changes:
* Entities now drive rendering:
* We extract "render components" from "app components" and store them _on_ entities. No more centralized uber lists! We now have true "ECS-driven rendering"
* To make this perform well, I implemented #2673 in upstream Bevy for fast batch insertions into specific entities. This was merged into the `pipelined-rendering` branch here: #2815
* Reworked the `Draw` abstraction:
* Generic `PhaseItems`: each draw phase can define its own type of "rendered thing", which can define its own "sort key"
* Ported the 2d, 3d, and shadow phases to the new PhaseItem impl (currently Transparent2d, Transparent3d, and Shadow PhaseItems)
* `Draw` trait and and `DrawFunctions` are now generic on PhaseItem
* Modular / Ergonomic `DrawFunctions` via `RenderCommands`
* RenderCommand is a trait that runs an ECS query and produces one or more RenderPass calls. Types implementing this trait can be composed to create a final DrawFunction. For example the DrawPbr DrawFunction is created from the following DrawCommand tuple. Const generics are used to set specific bind group locations:
```rust
pub type DrawPbr = (
SetPbrPipeline,
SetMeshViewBindGroup<0>,
SetStandardMaterialBindGroup<1>,
SetTransformBindGroup<2>,
DrawMesh,
);
```
* The new `custom_shader_pipelined` example illustrates how the commands above can be reused to create a custom draw function:
```rust
type DrawCustom = (
SetCustomMaterialPipeline,
SetMeshViewBindGroup<0>,
SetTransformBindGroup<2>,
DrawMesh,
);
```
* ExtractComponentPlugin and UniformComponentPlugin:
* Simple, standardized ways to easily extract individual components and write them to GPU buffers
* Ported PBR and Sprite rendering to the new primitives above.
* Removed staging buffer from UniformVec in favor of direct Queue usage
* Makes UniformVec much easier to use and more ergonomic. Completely removes the need for custom render graph nodes in these contexts (see the PbrNode and view Node removals and the much simpler call patterns in the relevant Prepare systems).
* Added a many_cubes_pipelined example to benchmark baseline 3d rendering performance and ensure there were no major regressions during this port. Avoiding regressions was challenging given that the old approach of extracting into centralized vectors is basically the "optimal" approach. However thanks to a various ECS optimizations and render logic rephrasing, we pretty much break even on this benchmark!
* Lifetimeless SystemParams: this will be a bit divisive, but as we continue to embrace "trait driven systems" (ex: ExtractComponentPlugin, UniformComponentPlugin, DrawCommand), the ergonomics of `(Query<'static, 'static, (&'static A, &'static B, &'static)>, Res<'static, C>)` were getting very hard to bear. As a compromise, I added "static type aliases" for the relevant SystemParams. The previous example can now be expressed like this: `(SQuery<(Read<A>, Read<B>)>, SRes<C>)`. If anyone has better ideas / conflicting opinions, please let me know!
* RunSystem trait: a way to define Systems via a trait with a SystemParam associated type. This is used to implement the various plugins mentioned above. I also added SystemParamItem and QueryItem type aliases to make "trait stye" ecs interactions nicer on the eyes (and fingers).
* RenderAsset retrying: ensures that render assets are only created when they are "ready" and allows us to create bind groups directly inside render assets (which significantly simplified the StandardMaterial code). I think ultimately we should swap this out on "asset dependency" events to wait for dependencies to load, but this will require significant asset system changes.
* Updated some built in shaders to account for missing MeshUniform fields
## Objective
The upcoming Bevy Book makes many references to the API documentation of bevy.
Most references belong to the first two chapters of the Bevy Book:
- bevyengine/bevy-website#176
- bevyengine/bevy-website#182
This PR attempts to improve the documentation of `bevy_ecs` and `bevy_app` in order to help readers of the Book who want to delve deeper into technical details.
## Solution
- Add crate and level module documentation
- Document the most important items (basically those included in the preludes), with the following style, where applicable:
- **Summary.** Short description of the item.
- **Second paragraph.** Detailed description of the item, without going too much in the implementation.
- **Code example(s).**
- **Safety or panic notes.**
## Collaboration
Any kind of collaboration is welcome, especially corrections, wording, new ideas and guidelines on where the focus should be put in.

### Related issues
- Fixes#2246
# Objective
[Tracy](https://github.com/wolfpld/tracy) is:
> A real time, nanosecond resolution, remote telemetry, hybrid frame and sampling profiler for games and other applications.
With the `trace_tracy` feature enabled, you run your bevy app and either a headless server (`capture`) or a live, interactive profiler UI (`Tracy`), and connect that to your bevy application to then stream the metric data and events, and save it or inspect it live/offline.
Previously when I implemented the spans across systems and stages and I was trying out different profiling tools, Tracy was too unstable on macOS to use. But now, quite some months later, it is working stably with Tracy 0.7.8. You can see timelines, aggregate statistics of mean system/stage execution times, and much more. It's very useful!
## Solution
- Use the `tracing-tracy` crate which supports our tracing spans
- Expose via the non-default feature `trace_tracy` for consistency with other `trace*` features
This updates the `pipelined-rendering` branch to use the latest `bevy_ecs` from `main`. This accomplishes a couple of goals:
1. prepares for upcoming `custom-shaders` branch changes, which were what drove many of the recent bevy_ecs changes on `main`
2. prepares for the soon-to-happen merge of `pipelined-rendering` into `main`. By including bevy_ecs changes now, we make that merge simpler / easier to review.
I split this up into 3 commits:
1. **add upstream bevy_ecs**: please don't bother reviewing this content. it has already received thorough review on `main` and is a literal copy/paste of the relevant folders (the old folders were deleted so the directories are literally exactly the same as `main`).
2. **support manual buffer application in stages**: this is used to enable the Extract step. we've already reviewed this once on the `pipelined-rendering` branch, but its worth looking at one more time in the new context of (1).
3. **support manual archetype updates in QueryState**: same situation as (2).
# Objective
- CI is failing again
- These failures result from https://github.com/rust-lang/rust/pull/85200
## Solution
- Fix the errors which result from this by using the given fields
- I also removed the now unused `Debug` impl.
I suspect that we shouldn't use -D warnings for nightly CI - ideally we'd get a discord webhook message into some (non-#github) dedicated channel on warnings.
But this does not implement that.
# Objective
The vast majority of `.single()` usage I've seen is immediately followed by a `.unwrap()`. Since it seems most people use it without handling the error, I think making it easier to just get what you want fast while also having a more verbose alternative when you want to handle the error could help.
## Solution
Instead of having a lot of `.unwrap()` everywhere, this PR introduces a `try_single()` variant that behaves like the current `.single()` and make the new `.single()` panic on error.
# Objective
- Fixes#2751
## Solution
- Avoid changing the window size if there is a scale factor override
- Can be tested with the `scale_factor_override` example - use <kbd>⏎</kbd> to active overriding the scale factor
A few minor changes to fix warnings emitted from clippy on the nightly toolchain, including redundant_allocation, unwrap_or_else_default, and collapsible_match, fixes#2698
# Objective
Make it easier to construct transforms. E.g.
```rs
Transform::from_xyz(0.0, 0.0, 10.0).with_scale(Vec3::splat(2.0))
```
I found myself writing an extension method to do this so I don't have to write:
```rs
Transform {
translation: Vec3::new(0.0, 0.0, 10.0),
scale: Vec3::splat(2.0),
..Default::default()
}
```
## Solution
Add *builder style* methods to `Transform`.
Methods:
- `with_translation`
- `with_rotation`
- `with_scale`
I also added these methods to `GlobalTransform`. But they are probably less useful there.

# Objective
Make it easier to check if some set of inputs matches a key, such as if you want to allow all of space or up or w for jumping.
Currently, this requires:
```rust
if keyboard.pressed(KeyCode::Space)
|| keyboard.pressed(KeyCode::Up)
|| keyboard.pressed(KeyCode::W) {
// ...
```
## Solution
Add an implementation of the helper methods, which very simply iterate through the items, used as:
```rust
if keyboard.any_pressed([KeyCode::Space, KeyCode::Up, KeyCode::W]) {
```
# Objective
Sometimes, the unwraps in `entity_mut` could fail here, if the entity was despawned *before* this command was applied.
The simplest case involves two command buffers:
```rust
use bevy::prelude::*;
fn b(mut commands1: Commands, mut commands2: Commands) {
let id = commands2.spawn().insert_bundle(()).id();
commands1.entity(id).despawn();
}
fn main() {
App::build().add_system(b.system()).run();
}
```
However, a more complicated version arises in the case of ambiguity:
```rust
use std::time::Duration;
use bevy::{app::ScheduleRunnerPlugin, prelude::*};
use rand::Rng;
fn cleanup(mut e: ResMut<Option<Entity>>) {
*e = None;
}
fn sleep_randomly() {
let mut rng = rand::thread_rng();
std:🧵:sleep(Duration::from_millis(rng.gen_range(0..50)));
}
fn spawn(mut commands: Commands, mut e: ResMut<Option<Entity>>) {
*e = Some(commands.spawn().insert_bundle(()).id());
}
fn despawn(mut commands: Commands, e: Res<Option<Entity>>) {
let mut rng = rand::thread_rng();
std:🧵:sleep(Duration::from_millis(rng.gen_range(0..50)));
if let Some(e) = *e {
commands.entity(e).despawn();
}
}
fn main() {
App::build()
.add_system(cleanup.system().label("cleanup"))
.add_system(sleep_randomly.system().label("before_despawn"))
.add_system(despawn.system().after("cleanup").after("before_despawn"))
.add_system(sleep_randomly.system().label("before_spawn"))
.add_system(spawn.system().after("cleanup").after("before_spawn"))
.insert_resource(None::<Entity>)
.add_plugin(ScheduleRunnerPlugin::default())
.run();
}
```
In the cases where this example crashes, it's because `despawn` was ordered before `spawn` in the topological ordering of systems (which determines when buffers are applied). However, `despawn` actually ran *after* `spawn`, because these systems are ambiguous, so the jiggles in the sleeping time triggered a case where this works.
## Solution
- Give a better error message
# Objective
Fix `Option<NonSend<T>>` to work when T isn't `Send`
Fix `Option<NonSendMut<T>>` to work when T isnt in the world.
## Solution
Simple two row fix, properly initialize T in `OptionNonSendState` and remove `T: Component` bound for `Option<NonSendMut<T>>`
also added a rudimentary test

# Objective
- Make it easy to use HexColorError with `thiserror`, i.e. converting it into other error types.
Makes this possible:
```rust
#[derive(Debug, thiserror::Error)]
pub enum LdtkError {
#[error("An error occured while deserializing")]
Json(#[from] serde_json::Error),
#[error("An error occured while parsing a color")]
HexColor(#[from] bevy::render::color::HexColorError),
}
```
## Solution
- Derive thiserror::Error the same way we do elsewhere (see query.rs for instance)
# Objective
- QueryState is lacking documentation.
Fixes#2090
## Solution
- Provide documentation that mirrors Query (as suggested in #2090) and modify as needed.

This upstreams the code changes used by the new renderer to enable cross-app Entity reuse:
* Spawning at specific entities
* get_or_spawn: spawns an entity if it doesn't already exist and returns an EntityMut
* insert_or_spawn_batch: the batched equivalent to `world.get_or_spawn(entity).insert_bundle(bundle)`
* Clearing entities and storages
* Allocating Entities with "invalid" archetypes. These entities cannot be queried / are treated as "non existent". They serve as "reserved" entities that won't show up when calling `spawn()`. They must be "specifically spawned at" using apis like `get_or_spawn(entity)`.
In combination, these changes enable the "render world" to clear entities / storages each frame and reserve all "app world entities". These can then be spawned during the "render extract step".
This refactors "spawn" and "insert" code in a way that I think is a massive improvement to legibility and re-usability. It also yields marginal performance wins by reducing some duplicate lookups (less than a percentage point improvement on insertion benchmarks). There is also some potential for future unsafe reduction (by making BatchSpawner and BatchInserter generic). But for now I want to cut down generic usage to a minimum to encourage smaller binaries and faster compiles.
This is currently a draft because it needs more tests (although this code has already had some real-world testing on my custom-shaders branch).
I also fixed the benchmarks (which currently don't compile!) / added new ones to illustrate batching wins.
After these changes, Bevy ECS is basically ready to accommodate the new renderer. I think the biggest missing piece at this point is "sub apps".
Makes some tweaks to the SubApp labeling introduced in #2695:
* Ergonomics improvements
* Removes unnecessary allocation when retrieving subapp label
* Removes the newly added "app macros" crate in favor of bevy_derive
* renamed RenderSubApp to RenderApp
@zicklag (for reference)
# Objective
- Clarify vague meaning of "Ltr" and "Rtl". For someone familiar with Flex Box, this is easy to understand, but being more explicit will help beginners or those unfamiliar, without the need to do research.
## Solution
- Change three letter abbreviation to fully descriptive name.
This matches `ahash::RandomState`, which provides both `Debug` and `Clone`.
Notably, implementing `Clone` allows the `StableHashMap`/`Set` to also implement `Clone`.
# Objective
- Allow `bevy_utils::StableHashMap` to be cloned.
## Solution
- Derive `Clone` for `bevy_utils::FixedState`.
- Also derive `Debug`, since we're touching it anyway, and this aligns `FixedState` with `ahash::RandomState`.
This is a rather simple but wide change, and it involves adding a new `bevy_app_macros` crate. Let me know if there is a better way to do any of this!
---
# Objective
- Allow adding and accessing sub-apps by using a label instead of an index
## Solution
- Migrate the bevy label implementation and derive code to the `bevy_utils` and `bevy_macro_utils` crates and then add a new `SubAppLabel` trait to the `bevy_app` crate that is used when adding or getting a sub-app from an app.
Updates the requirements on [glam](https://github.com/bitshifter/glam-rs) to permit the latest version.

# Objective
- We currently depends on ndk 0.2, 0.3, 0.4
- Only 0.2 dependencies comes from Bevy itself
## Solution
- Replace #1371
- Update Bevy to ndk-glue 0.4
- Also fixes duplicate dependency CI issue
# Objective
While implementing a plugin for my rollback networking library, I needed to load/save parts of the world. For this, I made a WorldSnapshot that works quite like the current DynamicScene. Using a TypeRegistry to register component types I want to save/load and then using ReflectComponents methods to add or apply components of the given types.
However, I noticed there is no method to remove components from entities through the ReflectComponent.
## Solution
I added a `remove_component` field to the `ReflectComponent` struct, as well as a `pub fn remove_component(&self, world: &mut World, entity: Entity)` to call that function in `remove_component`. This follows exactly the same pattern all other methods/fields in this struct look like.
This is an example how it could be used (at least how I would use it):
6c003f86f1/src/world_snapshot.rs (L133)
# Objective
Enable using exact World lifetimes during read-only access . This is motivated by the new renderer's need to allow read-only world-only queries to outlive the query itself (but still be constrained by the world lifetime).
For example:
115b170d1f/pipelined/bevy_pbr2/src/render/mod.rs (L774)
## Solution
Split out SystemParam state and world lifetimes and pipe those lifetimes up to read-only Query ops (and add into_inner for Res). According to every safety test I've run so far (except one), this is safe (see the temporary safety test commit). Note that changing the mutable variants to the new lifetimes would allow aliased mutable pointers (try doing that to see how it affects the temporary safety tests).
The new state lifetime on SystemParam does make `#[derive(SystemParam)]` more cumbersome (the current impl requires PhantomData if you don't use both lifetimes). We can make this better by detecting whether or not a lifetime is used in the derive and adjusting accordingly, but that should probably be done in its own pr.
## Why is this a draft?
The new lifetimes break QuerySet safety in one very specific case (see the query_set system in system_safety_test). We need to solve this before we can use the lifetimes given.
This is due to the fact that QuerySet is just a wrapper over Query, which now relies on world lifetimes instead of `&self` lifetimes to prevent aliasing (but in systems, each Query has its own implied lifetime, not a centralized world lifetime). I believe the fix is to rewrite QuerySet to have its own World lifetime (and own the internal reference). This will complicate the impl a bit, but I think it is doable. I'm curious if anyone else has better ideas.
Personally, I think these new lifetimes need to happen. We've gotta have a way to directly tie read-only World queries to the World lifetime. The new renderer is the first place this has come up, but I doubt it will be the last. Worst case scenario we can come up with a second `WorldLifetimeQuery<Q, F = ()>` parameter to enable these read-only scenarios, but I'd rather not add another type to the type zoo.
[**RENDERED**](https://github.com/alice-i-cecile/bevy/blob/better-contributing/CONTRIBUTING.md)
Improves #910. As discussed in #1309, we'll need to synchronize content between this and the Bevy website in some way (and clean up the .github file perhaps?).
I think doing it as a root-directory file is nicer for discovery, but that's a conversation I'm interested in having.
This document is intended to be helpful to beginners to open source and Bevy, and captures what I've learned about our informal practices and values.
Reviewers: I'm particularly interested in:
- opinions on the items **What we're trying to build**, where I discuss some of the project's high-level values and goals
- more relevant details on the `bevy` subcrates for **Getting oriented**
- useful tricks and best practices that I missed
- better guidance on how to contribute to the Bevy book from @cart <3
# Objective
This:
```rust
use bevy::prelude::*;
fn main() {
App::new()
.add_system(test)
.run();
}
fn test(entities: Query<Entity>) {
let mut combinations = entities.iter_combinations_mut();
while let Some([e1, e2]) = combinations.fetch_next() {
dbg!(e1);
}
}
```
fails with the message "the trait bound `bevy::ecs::query::EntityFetch: std::clone::Clone` is not satisfied".
## Solution
It works after adding the naive clone implementation to EntityFetch. I'm not super familiar with ECS internals, so I'd appreciate input on this.
## Objective
- Clean up remaining references to the trait `FromResources`, which was replaced in favor of `FromWorld` during the ECS rework.
## Solution
- Remove the derive macro for `FromResources`
- Change doc references of `FromResources` to `FromWorld`
(this is the first item in #2576)
# Objective
- Provides more useful error messages when using unsupported shader features.
## Solution Fixes#869
- Provided a error message as follows (adding name, set and binding):
```
Unsupported shader bind type CombinedImageSampler (name noiseVol0, set 0, binding 9)
```
This is an updated version of #1434 PR. I've encountered this macro problem while trying to use @woubuc's bevy-event-set crate.

I didn't know about MinimalPlugins for way too long. This should increase visibility for others.
# Objective
Improve visibility and discover in the docs for Default and Minimal Plugins.
## Solution
Links the two Docs pages.
Co-authored-by: Mirko Rainer <52899592+mirkoRainer@users.noreply.github.com>
# Objective
- Allow `ScheduleRunnerPlugin` to be instantiated without curly braces. Other plugins in the library already use the semicolon syntax.
- Currently, you have to do the following:
```rust
App::build()
.add_plugin(bevy::core::CorePlugin)
.add_plugin(bevy::app::ScheduleRunnerPlugin {})
```
- With the proposed change you can do this:
```rust
App::build()
.add_plugin(bevy::core::CorePlugin)
.add_plugin(bevy::app::ScheduleRunnerPlugin)
```
## Solution
- Change the `ScheduleRunnerPlugin` definition to use a semicolon instead of curly braces.
## Objective
This code would result in a crash:
```rust
use bevy::prelude::*;
fn main() {
let mut world = World::new();
let child = world.spawn().id();
world.spawn().push_children(&[child]);
}
```
## Solution
Update the `EntityMut`'s location after inserting a component on the children entities, as it may have changed.
# Objective
Port bevy_gltf to the pipelined-rendering branch.
## Solution
crates/bevy_gltf has been copied and pasted into pipelined/bevy_gltf2 and modifications were made to work with the pipelined-rendering branch. Notably vertex tangents and vertex colours are not supported.
Co-authored-by: Carter Anderson <mcanders1@gmail.com>
# Objective
notify 5.0.0-pre.11 breaks the interface again, but apparently in a way that's similar to how it used to be
## Solution
Bump `bevy_asset` dependency on notify to `5.0.0-pre.11` and fix the errors that crop up.
It looks like `pre.11` was mentioned in #2528 by @mockersf but there's no mention of why `pre.10` was chosen ultimately.
This decouples the opinionated "core pipeline" from the new (less opinionated) bevy_render crate. The "core pipeline" is intended to be used by crates like bevy_sprites, bevy_pbr, bevy_ui, and 3rd party crates that extends core rendering functionality.
# Objective
There is currently a 1-to-1 mapping between components and real rust types. This means that it is impossible for multiple components to be represented by the same rust type or for a component to not have a rust type at all. This means that component types can't be defined in languages other than rust like necessary for scripting or sandboxed (wasm?) plugins.
## Solution
Refactor `ComponentDescriptor` and `Bundle` to remove `TypeInfo`. `Bundle` now uses `ComponentId` instead. `ComponentDescriptor` is now always created from a rust type instead of through the `TypeInfo` indirection. A future PR may make it possible to construct a `ComponentDescriptor` from it's fields without a rust type being involved.
# Objective
- Remove all the `.system()` possible.
- Check for remaining missing cases.
## Solution
- Remove all `.system()`, fix compile errors
- 32 calls to `.system()` remains, mostly internals, the few others should be removed after #2446
# Objective
While looking at the code of `World`, I noticed two basic functions (`get` and `get_mut`) that are probably called a lot and with simple code that are not `inline`
## Solution
- Add benchmark to check impact
- Add `#[inline]`
```

This logic was in both `remove_bundle` and ` remove_bundle_intersection` but only differed by whether we call `.._forget_missing_..` or `.._drop_missing_..`
* bevy_pbr2: Add support for most of the StandardMaterial textures
Normal maps are not included here as they require tangents in a vertex attribute.
* bevy_pbr2: Ensure RenderCommandQueue is ready for PbrShaders init
* texture_pipelined: Add a light to the scene so we can see stuff
* WIP bevy_pbr2: back to front sorting hack
* bevy_pbr2: Uniform control flow for texture sampling in pbr.frag
From 'fintelia' on the Bevy Render Rework Round 2 discussion:
"My understanding is that GPUs these days never use the "execute both branches
and select the result" strategy. Rather, what they do is evaluate the branch
condition on all threads of a warp, and jump over it if all of them evaluate to
false. If even a single thread needs to execute the if statement body, however,
then the remaining threads are paused until that is completed."
* bevy_pbr2: Simplify texture and sampler names
The StandardMaterial_ prefix is no longer needed
* bevy_pbr2: Match default 'AmbientColor' of current bevy_pbr for now
* bevy_pbr2: Convert from non-linear to linear sRGB for the color uniform
* bevy_pbr2: Add pbr_pipelined example
* Fix view vector in pbr frag to work in ortho
* bevy_pbr2: Use a 90 degree y fov and light range projection for lights
* bevy_pbr2: Add AmbientLight resource
* bevy_pbr2: Convert PointLight color to linear sRGB for use in fragment shader
* bevy_pbr2: pbr.frag: Rename PointLight.projection to view_projection
The uniform contains the view_projection matrix so this was incorrect.
* bevy_pbr2: PointLight is an OmniLight as it has a radius
* bevy_pbr2: Factoring out duplicated code
* bevy_pbr2: Implement RenderAsset for StandardMaterial
* Remove unnecessary texture and sampler clones
* fix comment formatting
* remove redundant Buffer:from
* Don't extract meshes when their material textures aren't ready
* make missing textures in the queue step an error

This relicenses Bevy under the dual MIT or Apache-2.0 license. For rationale, see #2373.
* Changes the LICENSE file to describe the dual license. Moved the MIT license to docs/LICENSE-MIT. Added the Apache-2.0 license to docs/LICENSE-APACHE. I opted for this approach over dumping both license files at the root (the more common approach) for a number of reasons:
* Github links to the "first" license file (LICENSE-APACHE) in its license links (you can see this in the wgpu and rust-analyzer repos). People clicking these links might erroneously think that the apache license is the only option. Rust and Amethyst both use COPYRIGHT or COPYING files to solve this problem, but this creates more file noise (if you do everything at the root) and the naming feels way less intuitive.
* People have a reflex to look for a LICENSE file. By providing a single license file at the root, we make it easy for them to understand our licensing approach.
* I like keeping the root clean and noise free
* There is precedent for putting the apache and mit license text in sub folders (amethyst)
* Removed the `Copyright (c) 2020 Carter Anderson` copyright notice from the MIT license. I don't care about this attribution, it might make license compliance more difficult in some cases, and it didn't properly attribute other contributors. We shoudn't replace it with something like "Copyright (c) 2021 Bevy Contributors" because "Bevy Contributors" is not a legal entity. Instead, we just won't include the copyright line (which has precedent ... Rust also uses this approach).
* Updates crates to use the new "MIT OR Apache-2.0" license value
* Removes the old legion-transform license file from bevy_transform. bevy_transform has been its own, fully custom implementation for a long time and that license no longer applies.
* Added a License section to the main readme
* Updated our Bevy Plugin licensing guidelines.
As a follow-up we should update the website to properly describe the new license.
Closes#2373
This obsoletes #1111 and #2445, since @ColonisationCaptain and @temhotaokeaha haven't replied to #2373.
I believe that both of those PRs would be fine to keep, but they're even more fine to keep now :)
# Objective
- Continue work of #2398 and friends.
- Make `.system()` optional in chaining.
## Solution
- Slight change to `IntoChainSystem` signature and implementation.
- Remove some usages of `.system()` in the chaining example, to verify the implementation.
---
I swear, I'm not splitting these up on purpose, I just legit forgot about most of the things where `System` appears in public API, and my trait usage explorer mingles that with the gajillion internal uses.
In case you're wondering what happened to part 5, #2446 ate it.
# Objective
- Currently `Commands` are quite slow due to the need to allocate for each command and wrap it in a `Box<dyn Command>`.
- For example:
```rust
fn my_system(mut cmds: Commands) {
cmds.spawn().insert(42).insert(3.14);
}
```
will have 3 separate `Box<dyn Command>` that need to be allocated and ran.
## Solution
- Utilize a specialized data structure keyed `CommandQueueInner`.
- The purpose of `CommandQueueInner` is to hold a collection of commands in contiguous memory.
- This allows us to store each `Command` type contiguously in memory and quickly iterate through them and apply the `Command::write` trait function to each element.
# Objective
This fixes a crash caused by iOS preventing GPU access when not focused: #2296
## Solution
This skips `app.update()` in `winit_runner` when `winit` sends the `Suspended` event, until `Resumed`.
I've tested that this works for me on my iOS app.
This was tested using cargo generate-lockfile -Zminimal-versions.
The following indirect dependencies also have minimal version
dependencies. For at least num, rustc-serialize and rand this is
necessary to compile on rustc versions that are not older than 1.0.
* num = "0.1.27"
* rustc-serialize = "0.3.20"
* termcolor = "1.0.4"
* libudev-sys = "0.1.1"
* rand = "0.3.14"
* ab_glyph = "0.2.7
Based on https://github.com/bevyengine/bevy/pull/2455
# Objective
Reduce compilation time
# Solution
Remove unused dependencies. While this PR doesn't remove any crates from `Cargo.lock`, it may unlock more build parallelism.
I struggled with some sprite sheet animation which was like drifting from right to left.
This PR documents the current behaviour that the padding which is used on slicing a texture into a texture atlas, is assumed to be only between tiles. In my case I had some padding also on the right side of the texture.
In #2034, the `Remove` Command did not get the same treatment as the rest of the commands. There's no discussion saying it shouldn't have public fields, so I am assuming it was an oversight. This fixes that oversight.
# Objective
- Continue work of #2398 and friends.
- Make `.system()` optional in run criteria APIs.
## Solution
- Slight change to `RunCriteriaDescriptorCoercion` signature and implementors.
- Implement `IntoRunCriteria` for `IntoSystem` rather than `System`.
- Remove some usages of `.system()` with run criteria in tests of `stage.rs`, to verify the implementation.
# Objective
Fixes a possible deadlock between `AssetServer::get_asset_loader` / `AssetServer::add_loader`
A thread could take the `extension_to_loader_index` read lock,
and then have the `server.loader` write lock taken in add_loader
before it can. Then add_loader can't take the extension_to_loader_index
lock, and the program deadlocks.
To be more precise:
## Step 1: Thread 1 grabs the `extension_to_loader_index` lock on lines 138..139:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L133-L145)
## Step 2: Thread 2 grabs the `server.loader` write lock on line 107:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L103-L116)
## Step 3: Deadlock, since Thread 1 wants to grab `server.loader` on line 141...:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L133-L145)
... and Thread 2 wants to grab 'extension_to_loader_index` on lines 111..112:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L103-L116)
## Solution
Fixed by descoping the extension_to_loader_index lock, since
`get_asset_loader` doesn't need to hold the read lock on the extensions map for the duration,
just to get a copyable usize. The block might not be needed,
I think I could have gotten away with just inserting a `copied()`
call into the chain, but I wanted to make the reasoning clear for
future maintainers.
# Objective
I wanted to send the Bevy discord link to someone but couldn't find a pretty link to copy paste
## Solution
Use the vanity link we have for discord
# Objective
Fixes how the layer bit is unset in the RenderLayers bit mask when calling the `without` method.
## Solution
Unsets the layer bit using `&=` and the inverse of the layer bit mask.
# Objective
Beginners semi-regularly appear on the Discord asking for help with using `QuerySet` when they have a system with conflicting data access.
This happens because the Resulting Panic message only mentions `QuerySet` as a solution, even if in most cases `Without<T>` was enough to solve the problem.
## Solution
Mention the usage of `Without<T>` to create disjoint queries as an alternative to `QuerySet`
## Open Questions
- Is `disjoint` a too technical/mathematical word?
- Should `Without<T>` be mentioned before or after `QuerySet`?
- Before: Using `Without<T>` should be preferred and mentioning it first reinforces this for a reader.
- After: The Panics can be very long and a Reader could skip to end and only see the `QuerySet`

# Objective
- Continue work of #2398 and #2403.
- Make `.system()` syntax optional when using `.config()` API.
## Solution
- Introduce new prelude trait, `ConfigurableSystem`, that shorthands `my_system.system().config(...)` as `my_system.config(...)`.
- Expand `configure_system_local` test to also cover the new syntax.
# Objective
- Add inline documentation for `StorageType`.
- Currently the README in `bevy_ecs` provides docs for `StorageType`, however, adding addition inline docs makes it simpler for users who are actively reading the source code.
## Solution
- Add inline docs.
# Objective
- Extend work done in #2398.
- Make `.system()` syntax optional when using system descriptor API.
## Solution
- Slight change to `ParallelSystemDescriptorCoercion` signature and implementors.

I haven't touched exclusive systems, because it looks like the only two other solutions are going back to doubling our system insertion methods, or starting to lean into stageless. The latter will invalidate the former, so I think exclusive systems should remian pariahs until stageless.
I can grep & nuke `.system()` thorughout the codebase now, which might take a while, or we can do that in subsequent PR(s).
This can be your 6 months post-christmas present.
# Objective
- Make `.system` optional
- yeet
- It's ugly
- Alternative title: `.system` is dead; long live `.system`
- **yeet**
## Solution
- Use a higher ranked lifetime, and some trait magic.
N.B. This PR does not actually remove any `.system`s, except in a couple of examples. Once this is merged we can do that piecemeal across crates, and decide on syntax for labels.
# Objective
Re-introduce `AHashExt` and respective `with_capacity()` implementations to give a more ergonomic way to set a `HashMap` / `HashSet` capacity.
As a note, this has also been discussed and agreed on issue #2115, which this PR addresses (leaving `new()` out of the `AHashExt` trait).
Fixes#2115.
## Solution
PR #1235 had removed the `AHashExt` trait and respective `with_capacity()`s implementations, leaving only the less ergonomic `HashMap::with_capacity_and_hasher(size, Default::default())` option available.
This re-introduces `AHashExt` and respective `with_capacity()` implementations to give a more ergonomic way to set a `HashMap` / `HashSet` capacity.
# Objective
Currently, you can add `Option<Res<T>` or `Option<ResMut<T>` as a SystemParam, if the Resource could potentially not exist, but this functionality doesn't exist for `NonSend` and `NonSendMut`
## Solution
Adds implementations to use `Option<NonSend<T>>` and Option<NonSendMut<T>> as SystemParams.
Updates the requirements on [wgpu](https://github.com/gfx-rs/wgpu) to permit the latest version.

# Objective
- Make it so that `Time` can be cloned
- Makes it so I can clone the entire current `Time` and easily pass it to the user in [Rusty Engine](https://github.com/CleanCut/rusty_engine) instead of [doing this](8302dc3914/src/game.rs (L147-L150))
## Solution
- Derive the `Clone` trait on `Time`
# Objective
- CI jobs are starting to fail due to `clippy::bool-assert-comparison` and `clippy::single_component_path_imports` being triggered.
## Solution
- Fix all uses where `asset_eq!(<condition>, <bool>)` could be replace by `assert!`
- Move the `#[allow()]` for `single_component_path_imports` to `#![allow()]` at the start of the files.
# Objective
- Currently `AssetServer::get_handle_path` always returns `None` since the inner hash map is never written to.
## Solution
- Inside the `load_untracked` function, insert the asset path into the map.
This is similar to #1290 (thanks @TheRawMeatball)
# Objective
- The `DetectChanges` trait is used for types that detect change on mutable access (such as `ResMut`, `Mut`, etc...)
- `DetectChanges` was not implemented for `NonSendMut`
## Solution
- implement `NonSendMut` in terms of `DetectChanges`
# Objective
Currently, you can't call `is_added` or `is_changed` on a `NonSend` SystemParam, unless the Resource is a Component (implements `Send` and `Sync`).
This defeats the purpose of providing change detection for NonSend Resources.
While fixing this, I also noticed that `NonSend` does not have a bound at all on its struct.
## Solution
Change the bounds of `T` to always be `'static`.
# Objective
Prevent future unnecessary mental effort spent figuring out why this trait exists and how to resolve the `TODO`.
## Solution
I happened to notice this trait being used when expanding the `#[derive(Reflect)]` macro in my own crate to figure out how it worked, and noticed that there was a `TODO` comment on it because it is only used in the derive macro and thus appeared to be unused.
I figured I should document my findings to prevent someone else from finding them out the hard way in the future 😆
