# Objective
Fixes#8965.
#### Background
For convenience and to ensure everything is setup properly, we
automatically add certain bounds to the derived types. The current
implementation does this by taking the types from all active fields and
adding them to the where-clause of the generated impls. I believe this
method was chosen because it won't add bounds to types that are
otherwise ignored.
```rust
#[derive(Reflect)]
struct Foo<T, U: SomeTrait, V> {
t: T,
u: U::Assoc,
#[reflect(ignore)]
v: [V; 2]
}
// Generates something like:
impl<T, U: SomeTrait, V> for Foo<T, U, V>
where
// Active:
T: Reflect,
U::Assoc: Reflect,
// Ignored:
[V; 2]: Send + Sync + Any
{
// ...
}
```
The self-referential type fails because it ends up using _itself_ as a
type bound due to being one of its own active fields.
```rust
#[derive(Reflect)]
struct Foo {
foo: Vec<Foo>
}
// Foo where Vec<Foo>: Reflect -> Vec<T> where T: Reflect -> Foo where Vec<Foo>: Reflect -> ...
```
## Solution
We can't simply parse all field types for the name of our type. That
would be both complex and prone to errors and false-positives. And even
if it wasn't, what would we replace the bound with?
Instead, I opted to go for a solution that only adds the bounds to what
really needs it: the type parameters. While the bounds on concrete types
make errors a bit cleaner, they aren't strictly necessary. This means we
can change our generated where-clause to only add bounds to generic type
parameters.
Doing this, though, returns us back to the problem of over-bounding
parameters that don't need to be bounded. To solve this, I added a new
container attribute (based on
[this](https://github.com/dtolnay/syn/issues/422#issuecomment-406882925)
comment and @nicopap's
[comment](https://github.com/bevyengine/bevy/pull/9046#issuecomment-1623593780))
that allows us to pass in a custom where clause to modify what bounds
are added to these type parameters.
This allows us to do stuff like:
```rust
trait Trait {
type Assoc;
}
// We don't need `T` to be reflectable since we only care about `T::Assoc`.
#[derive(Reflect)]
#[reflect(where T::Assoc: FromReflect)]
struct Foo<T: Trait>(T::Assoc);
#[derive(TypePath)]
struct Bar;
impl Trait for Bar {
type Assoc = usize;
}
#[derive(Reflect)]
struct Baz {
a: Foo<Bar>,
}
```
> **Note**
> I also
[tried](dc139ea34c)
allowing `#[reflect(ignore)]` to be used on the type parameters
themselves, but that proved problematic since the derive macro does not
consume the attribute. This is why I went with the container attribute
approach.
### Alternatives
One alternative could possibly be to just not add reflection bounds
automatically (i.e. only add required bounds like `Send`, `Sync`, `Any`,
and `TypePath`).
The downside here is we add more friction to using reflection, which
already comes with its own set of considerations. This is a potentially
viable option, but we really need to consider whether or not the
ergonomics hit is worth it.
If we did decide to go the more manual route, we should at least
consider something like #5772 to make it easier for users to add the
right bounds (although, this could still become tricky with
`FromReflect` also being automatically derived).
### Open Questions
1. Should we go with this approach or the manual alternative?
2. ~~Should we add a `skip_params` attribute to avoid the `T: 'static`
trick?~~ ~~Decided to go with `custom_where()` as it's the simplest~~
Scratch that, went with a normal where clause
3. ~~`custom_where` bikeshedding?~~ No longer needed since we are using
a normal where clause
### TODO
- [x] Add compile-fail tests
---
## Changelog
- Fixed issue preventing recursive types from deriving `Reflect`
- Changed how where-clause bounds are generated by the `Reflect` derive
macro
- They are now only applied to the type parameters, not to all active
fields
- Added `#[reflect(where T: Trait, U::Assoc: Trait, ...)]` container
attribute
## Migration Guide
When deriving `Reflect`, generic type params that do not need the
automatic reflection bounds (such as `Reflect`) applied to them will
need to opt-out using a custom where clause like: `#[reflect(where T:
Trait, U::Assoc: Trait, ...)]`.
The attribute can define custom bounds only used by the reflection
impls. To simply opt-out all the type params, we can pass in an empty
where clause: `#[reflect(where)]`.
```rust
// BEFORE:
#[derive(Reflect)]
struct Foo<T>(#[reflect(ignore)] T);
// AFTER:
#[derive(Reflect)]
#[reflect(where)]
struct Foo<T>(#[reflect(ignore)] T);
```

# Objective
- Implement common traits on primitives
## Solution
- Derive PartialEq on types that were missing it.
- Derive Copy on small types that were missing it.
- Derive Serialize/Deserialize if the feature on bevy_math is enabled.
- Add a lot of cursed stuff to the bevy_reflect `impls` module.
# Objective
- I wanted this for an example, and I think it's a fundamentally handy
debugging tool (with already public fields).
## Solution
- `derive(Debug)` for `FrameCount`
# Objective
- Fixes#11453
This is a temporary fix. There is PR fixing it (#11460), but I'm not
sure if it's going to be merged before the 0.13 release.
# Objective
- Implement an arc3d API for gizmos
- Solves #11536
## Solution
### `arc_3d`
- The current `arc3d` method on gizmos only takes an angle
- It draws an "standard arc" by default, this is an arc starting at
`Vec3::X`, in the XZ plane, in counter clockwise direction with a normal
that is facing up
- The "standard arc" can be customized with the usual gizmo builder
pattern. This way you'll be able to draw arbitrary arcs
### `short/long_arc_3d_between`
- Given `center`, `from`, `to` draws an arc between `from` and `to`
---
## Changelog
> This section is optional. If this was a trivial fix, or has no
externally-visible impact, you can delete this section.
- Added: `Gizmos::arc3d(&mut self, angle)` method
- Added: `Gizmos::long_arc_3d_between(&mut self, center, from, to)`
method
- Added: `Gizmos::short_arc_3d_between(&mut self, center, from, to)`
method

This PR factors out an orthogonal part of another PR as mentioned in
[this
comment](https://github.com/bevyengine/bevy/pull/11072#issuecomment-1883859573)
# Objective
Fixes#11311
## Solution
Adds an example to the documentation for `par_iter_mut`. I didn't add
any examples to `par_iter`, because I couldn't think of a good example
and I figure users can infer that `par_iter` and `par_iter_mut` are
similar.
# Objective
It's sometimes desirable to get a `Res<T>` rather than `&T` from
`World::get_resource`.
Alternative to #9940, partly adresses #9926
## Solution
added additional methods to `World` and `UnsafeWorldCell` to retrieve a
resource wrapped in a `Res`.
- `UnsafeWorldCell::get_resource_ref`
- `World::get_resource_ref`
- `World::resource_ref`
I can change it so `World::resource_mut` returns `ResMut` instead of
`Mut` as well if that's desired, but that could also be added later in a
seperate pr.

# Objective
Allow TextureAtlasBuilder in AssetLoader.
Fixes#2987
## Solution
- TextureAtlasBuilder no longer hold just AssetIds that are used to
retrieve the actual image data in `finish`, but &Image instead.
- TextureAtlasBuilder now required AssetId only optionally (and it is
only used to retrieve the index from the AssetId in TextureAtlasLayout),
## Issues
- The issue mentioned here
https://github.com/bevyengine/bevy/pull/11474#issuecomment-1904676937
now also extends to the actual atlas texture. In short: Calling
add_texture multiple times for the same texture will lead to duplicate
image data in the atlas texture and additional indices.
If you provide an AssetId we can probably do something to de-duplicate
the entries while keeping insertion order (suggestions welcome on how
exactly). But if you don't then we are out of luck (unless we can and
want to hash the image, which I do not think we want).
---
## Changelog
### Changed
- TextureAtlasBuilder `add_texture` can be called without providing an
AssetId
- TextureAtlasBuilder `finish` no longer takes Assets<Image> and no
longer returns a Handle<Image>
## Migration Guide
- For `add_texture` you need to wrap your AssetId in Some
- `finish` now returns the atlas texture image directly instead of a
handle. Provide the atlas texture to `add` on Assets<Texture> to get a
Handle<Image>
# Objective
allow automatic fixing of bad joint weights.
fix#10447
## Solution
- remove automatic normalization of vertexes with all zero joint
weights.
- add `Mesh::normalize_joint_weights` which fixes zero joint weights,
and also ensures that all weights sum to 1. this is a manual call as it
may be slow to apply to large skinned meshes, and is unnecessary if you
have control over the source assets.
note: this became a more significant problem with 0.12, as weights that
are close to, but not exactly 1 now seem to use `Vec3::ZERO` for the
unspecified weight, where previously they used the entity translation.
# Objective
DXC+DX12 debug builds with an environment map have been broken since
https://github.com/bevyengine/bevy/pull/11366 merged due to an internal
compiler error in DXC. I tracked it down to a single `break` statement
and reported it upstream
(https://github.com/microsoft/DirectXShaderCompiler/issues/6183)
## Solution
Workaround the ICE by setting the for loop index variable to the max
value of the loop to avoid the `break` that's causing the ICE.
This works because it's the last thing in the for loop.
The `reflection_probes` and `pbr` examples both appear to still work
correctly.
# Objective
After #10520, I was experiencing seriously degraded performance that
ended up being due to never-drained `AssetEvent` events causing havoc
inside `extract_render_asset::<A>`. The same events being read over and
over again meant the same assets were being prepared every frame for
eternity. For what it's worth, I was noticing this on a static scene
about every 3rd or so time running my project.
* References #10520
* Fixes#11240
Why these events aren't sometimes drained between frames is beyond me
and perhaps worthy of another investigation, but the approach in this PR
effectively restores the original cached `EventReader` behavior (which
fixes it).
## Solution
I followed the [`CachedSystemState`
example](3a666cab23/crates/bevy_ecs/src/system/function_system.rs (L155))
to make sure that the `EventReader` state is cached between frames like
it used to be when it was an argument of `extract_render_asset::<A>`.
# Objective
Plugins are an incredible tool for encapsulating functionality. They are
low-key one of Bevy's best features. Combined with rust's module and
privacy system, it's a match made in heaven.
The one downside is that they can be a little too verbose to define. 90%
of all plugin definitions look something like this:
```rust
pub struct MyPlugin;
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.init_resource::<CameraAssets>()
.add_event::<SetCamera>()
.add_systems(Update, (collect_set_camera_events, drive_camera).chain());
}
}
```
Every so often it gets a little spicier:
```rust
pub struct MyGenericPlugin<T>(PhantomData<T>);
impl<T> Default for MyGenericPlugin<T> {
fn default() -> Self { ... }
}
impl<T> Plugin for MyGenericPlugin<T> { ... }
```
This is an annoying amount of boilerplate. Ideally, plugins should be
focused and small in scope, which means any app is going to have a *lot*
of them. Writing a plugin should be as easy as possible, and the *only*
part of this process that carries any meaning is the body of `fn build`.
## Solution
Implement `Plugin` for functions that take `&mut App` as a parameter.
The two examples above now look like this:
```rust
pub fn my_plugin(app: &mut App) {
app.init_resource::<CameraAssets>()
.add_event::<SetCamera>()
.add_systems(Update, (collect_set_camera_events, drive_camera).chain());
}
pub fn my_generic_plugin<T>(app: &mut App) {
// No need for PhantomData, it just works.
}
```
Almost all plugins can be written this way, which I believe will make
bevy code much more attractive. Less boilerplate and less meaningless
indentation. More plugins with smaller scopes.
---
## Changelog
The `Plugin` trait is now implemented for all functions that take `&mut
App` as their only parameter. This is an abbreviated way of defining
plugins with less boilerplate than manually implementing the trait.

# Objective
Fixes#11533
When `AssetPath`s are created from a string type, they are parsed into
an `AssetSource`, a `Path`, and a `Label`.
The current method of parsing has some unnecessary quirks:
- The presence of a `:` character is assumed to be the start of an asset
source indicator.
- This is not necessarily true. There are valid uses of a `:` character
in an asset path, for example an http source's port such as
`localhost:80`.
- If there are multiple instances of `://`, the last one is assumed to
be the asset source deliminator.
- This has some unexpected behavior. Even in a fully formed path, such
as `http://localhost:80`, the `:` between `localhost` and `80` is
assumed to be the start of an asset source, causing an error since it
does not form the full sequence `://`.
## Solution
Changes the `AssetPath`'s `parse_internal` method to be more permissive.
- Only the exact sequence `://` is taken to be the asset source
deliminator, and only the first one if there are multiple.
- As a consequence, it is no longer possible to detect a malformed asset
source deliminator, and so the corresponding error was removed.
# Objective
https://github.com/bevyengine/bevy/pull/5103 caused a bug where
`Sprite::rect` was ignored by the engine. (Did nothing)
## Solution
My solution changes the way how Bevy calculates the rect, based on this
table:
| `atlas_rect` | `Sprite::rect` | Result |
|--------------|----------------|------------------------------------------------------|
| `None` | `None` | `None` |
| `None` | `Some` | `Sprite::rect` |
| `Some` | `None` | `atlas_rect` |
| `Some` | `Some` | `Sprite::rect` is used, relative to `atlas_rect.min`
|
# Objective
One of a few Bevy Asset improvements I would like to make: #11216.
Currently asset processing and asset saving are handled by the same
trait, `AssetSaver`. This makes it difficult to reuse saving
implementations and impossible to have a single "universal" saver for a
given asset type.
## Solution
This PR splits off the processing portion of `AssetSaver` into
`AssetTransformer`, which is responsible for transforming assets. This
change involves adding the `LoadTransformAndSave` processor, which
utilizes the new API. The `LoadAndSave` still exists since it remains
useful in situations where no "transformation" of the asset is done,
such as when compressing assets.
## Notes:
As an aside, Bikeshedding is welcome on the names. I'm not entirely
convinced by `AssetTransformer`, which was chosen mostly because
`AssetProcessor` is taken. Additionally, `LoadTransformSave` may be
sufficient instead of `LoadTransformAndSave`.
---
## Changelog
### Added
- `AssetTransformer` which is responsible for transforming Assets.
- `LoadTransformAndSave`, a `Process` implementation.
### Changed
- Changed `AssetSaver`'s responsibilities from processing and saving to
just saving.
- Updated `asset_processing` example to use new API.
- Old asset .meta files regenerated with new processor.
# Objective
Keep core dependencies up to date.
## Solution
Update the dependencies.
wgpu 0.19 only supports raw-window-handle (rwh) 0.6, so bumping that was
included in this.
The rwh 0.6 version bump is just the simplest way of doing it. There
might be a way we can take advantage of wgpu's new safe surface creation
api, but I'm not familiar enough with bevy's window management to
untangle it and my attempt ended up being a mess of lifetimes and rustc
complaining about missing trait impls (that were implemented). Thanks to
@MiniaczQ for the (much simpler) rwh 0.6 version bump code.
Unblocks https://github.com/bevyengine/bevy/pull/9172 and
https://github.com/bevyengine/bevy/pull/10812
~~This might be blocked on cpal and oboe updating their ndk versions to
0.8, as they both currently target ndk 0.7 which uses rwh 0.5.2~~ Tested
on android, and everything seems to work correctly (audio properly stops
when minimized, and plays when re-focusing the app).
---
## Changelog
- `wgpu` has been updated to 0.19! The long awaited arcanization has
been merged (for more info, see
https://gfx-rs.github.io/2023/11/24/arcanization.html), and Vulkan
should now be working again on Intel GPUs.
- Targeting WebGPU now requires that you add the new `webgpu` feature
(setting the `RUSTFLAGS` environment variable to
`--cfg=web_sys_unstable_apis` is still required). This feature currently
overrides the `webgl2` feature if you have both enabled (the `webgl2`
feature is enabled by default), so it is not recommended to add it as a
default feature to libraries without putting it behind a flag that
allows library users to opt out of it! In the future we plan on
supporting wasm binaries that can target both webgl2 and webgpu now that
wgpu added support for doing so (see
https://github.com/bevyengine/bevy/issues/11505).
- `raw-window-handle` has been updated to version 0.6.
## Migration Guide
- `bevy_render::instance_index::get_instance_index()` has been removed
as the webgl2 workaround is no longer required as it was fixed upstream
in wgpu. The `BASE_INSTANCE_WORKAROUND` shaderdef has also been removed.
- WebGPU now requires the new `webgpu` feature to be enabled. The
`webgpu` feature currently overrides the `webgl2` feature so you no
longer need to disable all default features and re-add them all when
targeting `webgpu`, but binaries built with both the `webgpu` and
`webgl2` features will only target the webgpu backend, and will only
work on browsers that support WebGPU.
- Places where you conditionally compiled things for webgl2 need to be
updated because of this change, eg:
- `#[cfg(any(not(feature = "webgl"), not(target_arch = "wasm32")))]`
becomes `#[cfg(any(not(feature = "webgl") ,not(target_arch = "wasm32"),
feature = "webgpu"))]`
- `#[cfg(all(feature = "webgl", target_arch = "wasm32"))]` becomes
`#[cfg(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))]`
- `if cfg!(all(feature = "webgl", target_arch = "wasm32"))` becomes `if
cfg!(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))`
- `create_texture_with_data` now also takes a `TextureDataOrder`. You
can probably just set this to `TextureDataOrder::default()`
- `TextureFormat`'s `block_size` has been renamed to `block_copy_size`
- See the `wgpu` changelog for anything I might've missed:

# Objective
Make APIs more consistent and ergonomic by adding a `new` constructor
for `Circle` and `Sphere`.
This could be seen as a redundant "trivial constructor", but in
practise, it seems valuable to me. I have lots of cases where formatting
becomes ugly because of the lack of a constructor, like this:
```rust
Circle {
radius: self.radius(),
}
.contains_local_point(centered_pt)
```
With `new`, it'd be formatted much nicer:
```rust
Circle::new(self.radius()).contains_local_point(centered_pt)
```
Of course, this is just one example, but my circle/sphere definitions
very frequently span three or more lines when they could fit on one.
Adding `new` also increases consistency. `Ellipse` has `new` already,
and so does the mesh version of `Circle`.
## Solution
Add a `new` constructor for `Circle` and `Sphere`.

While working on #11527 I spotted that the internal field for the label
of a `Schedule` is called `name`. Using `label` seems more in line with
the other naming across Bevy.
## Solution
Renaming the field was straightforward since it's not exposed outside of
the module. This also means a changelog or migration guide isn't
necessary.
# Objective
Fixes#11411
## Solution
- Added a simple example how to create and configure custom schedules
that are run by the `Main` schedule.
- Spot checked some of the API docs used, fixed `App::add_schedule` docs
that referred to a function argument that was removed by #9600.
## Open Questions
- While spot checking the docs, I noticed that the `Schedule` label is
stored in a field called `name` instead of `label`. This seems
unintuitive since the term label is used everywhere else. Should we
change that field name? It was introduced in #9600. If so, I do think
this change would be out of scope for this PR that mainly adds the
example.
# Objective
Rust analyzer kept complaining about a cyclic dependency due to
`bevy_input` having a dev-dependency on `bevy`.
`bevy_input` was also missing `bevy_reflect`'s "smol_str" feature which
it needs to compile on its own.
Fixes#10256
## Solution
Remove the dev-dependency on `bevy` from `bevy_input` since it was only
used to reduce imports for 1 test and 3 doc examples by 1 line each, as
`bevy_input` already has dependencies on everything needed for those
tests and doctests to work.
Add `bevy_reflect`'s "smol_str" feature to `bevy_input`'s dependency
list as it needs it to actually compile.
# Objective
Fixes#10414.
That issue and its comments do a great job of laying out the case for
this.
## Solution
Added an optional `spatial_scale` field to `PlaybackSettings`, which
overrides the default value set on `AudioPlugin`.
## Changelog
- `AudioPlugin::spatial_scale` has been renamed to
`default_spatial_scale`.
- `SpatialScale` is no longer a resource and is wrapped by
`DefaultSpatialScale`.
- Added an optional `spatial_scale` to `PlaybackSettings`.
## Migration Guide
`AudioPlugin::spatial_scale` has been renamed to `default_spatial_scale`
and the default spatial scale can now be overridden on individual audio
sources with `PlaybackSettings::spatial_scale`.
If you were modifying or reading `SpatialScale` at run time, use
`DefaultSpatialScale` instead.
```rust
// before
app.add_plugins(DefaultPlugins.set(AudioPlugin {
spatial_scale: SpatialScale::new(AUDIO_SCALE),
..default()
}));
// after
app.add_plugins(DefaultPlugins.set(AudioPlugin {
default_spatial_scale: SpatialScale::new(AUDIO_SCALE),
..default()
}));
```

# Objective
- `AssetPath` implements reflection, but is not registered as a type in
the plugin.
- Fixes#11481.
## Solution
- Register the `AssetPath` type when `AssetPlugin::build` is called.
---
## Changelog
- Registered `AssetPath` type for use in reflection.
# Objective
- `World::get_resource`'s comment on it's `unsafe` usage meant to say
"mutably" but instead said "immutably."
- Fixes#11430.
## Solution
- Replace "immutably" with "mutably."
# Objective
#10946 added bounding volume types and an `IntersectsVolume` trait, but
didn't actually implement intersections between bounding volumes.
This PR implements AABB-AABB, circle-circle / sphere-sphere, and
AABB-circle / AABB-sphere intersections.
## Solution
Implement `IntersectsVolume` for bounding volume pairs. I also added
`closest_point` methods to return the closest point on the surface /
inside of bounding volumes. This is used for AABB-circle / AABB-sphere
intersections.

# Objective
TextureAtlases are commonly used to drive animations described as a
consecutive range of indices. The current TextureAtlasBuilder uses the
AssetId of the image to determine the index of the texture in the
TextureAtlas. The AssetId of an Image Asset can change between runs.
The TextureAtlas exposes
[`get_texture_index`](https://docs.rs/bevy/latest/bevy/sprite/struct.TextureAtlas.html#method.get_texture_index)
to get the index from a given AssetId, but this needlessly complicates
the process of creating a simple TextureAtlas animation.
Fixes#2459
## Solution
- Use the (ordered) image_ids of the 'texture to place' vector to
retrieve the packed locations and compose the textures of the
TextureAtlas.
# Objective
It would be convenient to be able to call functions with `Commands` as a
parameter without having to move your own instance of `Commands`. Since
this struct is composed entirely of references, we can easily get an
owned instance of `Commands` by shortening the lifetime.
## Solution
Add `Commands::reborrow`, `EntiyCommands::reborrow`, and
`Deferred::reborrow`, which returns an owned version of themselves with
a shorter lifetime.
Remove unnecessary lifetimes from `EntityCommands`. The `'w` and `'s`
lifetimes only have to be separate for `Commands` because it's used as a
`SystemParam` -- this is not the case for `EntityCommands`.
---
## Changelog
Added `Commands::reborrow`. This is useful if you have `&mut Commands`
but need `Commands`. Also added `EntityCommands::reborrow` and
`Deferred:reborrow` which serve the same purpose.
## Migration Guide
The lifetimes for `EntityCommands` have been simplified.
```rust
// Before (Bevy 0.12)
struct MyStruct<'w, 's, 'a> {
commands: EntityCommands<'w, 's, 'a>,
}
// After (Bevy 0.13)
struct MyStruct<'a> {
commands: EntityCommands<'a>,
}
```
The method `EntityCommands::commands` now returns `Commands` rather than
`&mut Commands`.
```rust
// Before (Bevy 0.12)
let commands = entity_commands.commands();
commands.spawn(...);
// After (Bevy 0.13)
let mut commands = entity_commands.commands();
commands.spawn(...);
```
# Objective
Document a few common cases of which lifetime is required when using
SystemParam Derive
## Solution
Added a table in the doc comment

# Objective
- Prep for https://github.com/bevyengine/bevy/pull/10164
- Make deferred_lighting_pass_id a ColorAttachment
- Correctly extract shadow view frusta so that the view uniforms get
populated
- Make some needed things public
- Misc formatting
# Objective
- Extend reflection to the standard library's `Wrapping` and
`Saturating` generic types.
This wasn't my use-case but someone in the discord was surprised that
this wasn't already done. I decided to make a PR because the other
`std::num` items were reflected and if there's a reason to exclude
`Wrapping` and `Saturating`, I am unaware of it.
## Solution
Trivial fix
---
## Changelog
Implemented `Reflect` for `Wrapping<T>` and `Saturating<T>` from
`std::num`.
# Objective
> Can anyone explain to me the reasoning of renaming all the types named
Query to Data. I'm talking about this PR
https://github.com/bevyengine/bevy/pull/10779 It doesn't make sense to
me that a bunch of types that are used to run queries aren't named Query
anymore. Like ViewQuery on the ViewNode is the type of the Query. I
don't really understand the point of the rename, it just seems like it
hides the fact that a query will run based on those types.

## Solution
Revert several renames in #10779.
## Changelog
- `ViewNode::ViewData` is now `ViewNode::ViewQuery` again.
## Migration Guide
- This PR amends the migration guide in

# Objective
- Add the ability to describe storage texture bindings when deriving
`AsBindGroup`.
- This is especially valuable for the compute story of bevy which
deserves some extra love imo.
## Solution
- This add the ability to annotate struct fields with a
`#[storage_texture(0)]` annotation.
- Instead of adding specific option parsing for all the image formats
and access modes, I simply accept a token stream and defer checking to
see if the option is valid to the compiler. This still results in useful
and friendly errors and is free to maintain and always compatible with
wgpu changes.
---
## Changelog
- The `#[storage_texture(..)]` annotation is now accepted for fields of
`Handle<Image>` in structs that derive `AsBindGroup`.
- The game_of_life compute shader example has been updated to use
`AsBindGroup` together with `[storage_texture(..)]` to obtain the
`BindGroupLayout`.
## Migration Guide
# Objective
#8219 changed the target type of a `transmute` without changing the one
transmuting from ([see the relevant
diff](55e9ab7c92 (diff-11413fb2eeba97978379d325353d32aa76eefd0af0c8e9b50b7f394ddfda7a26R351-R355))),
making them incompatible. This PR fixes this by changing the initial
type to match the target one (modulo lifetimes).
## Solution
Change the type to be transmuted from to match the one transmuting into
(modulo lifetimes)
# Objective
- This PR makes it so that `ReflectSerialize` and `ReflectDeserialize`
traits are properly derived on `Name`. This avoids having the internal
hash “leak” into the serialization when using reflection.
## Solution
- Added a conditional derive for `ReflectDeserialize` and
`ReflectSerialize` via `#[cfg_attr()]`
---
## Changelog
- `Name` now implements `ReflectDeserialize` and `ReflectSerialize`
whenever the `serialize` feature is enabled.
# Objective
Fix weird visuals when drawing a gizmo with a non-normed normal.
Fixes#11401
## Solution
Just normalize right before we draw. Could do it when constructing the
builder but that seems less consistent.
## Changelog
- gizmos.circle normal is now a Direction3d instead of a Vec3.
## Migration Guide
- Pass a Direction3d for gizmos.circle normal, eg.
`Direction3d::new(vec).unwrap_or(default)` or potentially
`Direction3d::new_unchecked(vec)` if you know your vec is definitely
normalized.
