# Objective
- Fix adding `#![allow(clippy::type_complexity)]` everywhere. like #9796
## Solution
- Use the new [lints] table that will land in 1.74
(https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#lints)
- inherit lint to the workspace, crates and examples.
```
[lints]
workspace = true
```
## Changelog
- Bump rust version to 1.74
- Enable lints table for the workspace
```toml
[workspace.lints.clippy]
type_complexity = "allow"
```
- Allow type complexity for all crates and examples
```toml
[lints]
workspace = true
```

# Objective
Fixes#5101
Alternative to #6511
## Solution
Corrected the behavior for ignored fields in `FromReflect`, which was
previously using the incorrect field indexes.
Similarly, fields marked with `#[reflect(skip_serializing)]` no longer
break when using `FromReflect` after deserialization. This was done by
modifying `SerializationData` to store a function pointer that can later
be used to generate a default instance of the skipped field during
deserialization.
The function pointer points to a function generated by the derive macro
using the behavior designated by `#[reflect(default)]` (or just
`Default` if none provided). The entire output of the macro is now
wrapped in an [unnamed
constant](https://doc.rust-lang.org/stable/reference/items/constant-items.html#unnamed-constant)
which keeps this behavior hygienic.
#### Rationale
The biggest downside to this approach is that it requires fields marked
`#[reflect(skip_serializing)]` to provide the ability to create a
default instance— either via a `Default` impl or by specifying a custom
one. While this isn't great, I think it might be justified by the fact
that we really need to create this value when using `FromReflect` on a
deserialized object. And we need to do this _during_ deserialization
because after that (at least for tuples and tuple structs) we lose
information about which field is which: _"is the value at index 1 in
this `DynamicTupleStruct` the actual value for index 1 or is it really
the value for index 2 since index 1 is skippable...?"_
#### Alternatives
An alternative would be to store `Option<Box<dyn Reflect>>` within
`DynamicTuple` and `DynamicTupleStruct` instead of just `Box<dyn
Reflect>`. This would allow us to insert "empty"/"missing" fields during
deserialization, thus saving the positional information of the skipped
fields. However, this may require changing the API of `Tuple` and
`TupleStruct` such that they can account for their dynamic counterparts
returning `None` for a skipped field. In practice this would probably
mean exposing the `Option`-ness of the dynamics onto implementors via
methods like `Tuple::drain` or `TupleStruct::field`.
Personally, I think requiring `Default` would be better than muddying up
the API to account for these special cases. But I'm open to trying out
this other approach if the community feels that it's better.

## Changelog
### Public Changes
#### Fixed
- The behaviors of `#[reflect(ignore)]` and
`#[reflect(skip_serializing)]` are no longer dependent on field order
#### Changed
- Fields marked with `#[reflect(skip_serializing)]` now need to either
implement `Default` or specify a custom default function using
`#[reflect(default = "path::to::some_func")]`
- Deserializing a type with fields marked `#[reflect(skip_serializing)]`
will now include that field initialized to its specified default value
- `SerializationData::new` now takes the new `SkippedField` struct along
with the skipped field index
- Renamed `SerializationData::is_ignored_field` to
`SerializationData::is_field_skipped`
#### Added
- Added `SkippedField` struct
- Added methods `SerializationData::generate_default` and
`SerializationData::iter_skipped`
### Internal Changes
#### Changed
- Replaced `members_to_serialization_denylist` and `BitSet<u32>` with
`SerializationDataDef`
- The `Reflect` derive is more hygienic as it now outputs within an
[unnamed
constant](https://doc.rust-lang.org/stable/reference/items/constant-items.html#unnamed-constant)
- `StructField::index` has been split up into
`StructField::declaration_index` and `StructField::reflection_index`
#### Removed
- Removed `bitset` dependency
## Migration Guide
* Fields marked `#[reflect(skip_serializing)]` now must implement
`Default` or specify a custom default function with `#[reflect(default =
"path::to::some_func")]`
```rust
#[derive(Reflect)]
struct MyStruct {
#[reflect(skip_serializing)]
#[reflect(default = "get_foo_default")]
foo: Foo, // <- `Foo` does not impl `Default` so requires a custom
function
#[reflect(skip_serializing)]
bar: Bar, // <- `Bar` impls `Default`
}
#[derive(Reflect)]
struct Foo(i32);
#[derive(Reflect, Default)]
struct Bar(i32);
fn get_foo_default() -> Foo {
Foo(123)
}
```
* `SerializationData::new` has been changed to expect an iterator of
`(usize, SkippedField)` rather than one of just `usize`
```rust
// BEFORE
SerializationData::new([0, 3].into_iter());
// AFTER
SerializationData::new([
(0, SkippedField::new(field_0_default_fn)),
(3, SkippedField::new(field_3_default_fn)),
].into_iter());
```
* `Serialization::is_ignored_field` has been renamed to
`Serialization::is_field_skipped`
* Fields marked `#[reflect(skip_serializing)]` are now included in
deserialization output. This may affect logic that expected those fields
to be absent.

I created this manually as Github didn't want to run CI for the
workflow-generated PR. I'm guessing we didn't hit this in previous
releases because we used bors.

# Objective
Resolves#6197
Make it so that doc comments can be retrieved via reflection.
## Solution
Adds the new `documentation` feature to `bevy_reflect` (disabled by default).
When enabled, documentation can be found using `TypeInfo::doc` for reflected types:
```rust
/// Some struct.
///
/// # Example
///
/// ```ignore
/// let some_struct = SomeStruct;
/// ```
#[derive(Reflect)]
struct SomeStruct;
let info = <SomeStruct as Typed>::type_info();
assert_eq!(
Some(" Some struct.\n\n # Example\n\n ```ignore\n let some_struct = SomeStruct;\n ```"),
info.docs()
);
```
### Notes for Reviewers
The bulk of the files simply added the same 16 lines of code (with slightly different documentation). Most of the real changes occur in the `bevy_reflect_derive` files as well as in the added tests.
---
## Changelog
* Added `documentation` feature to `bevy_reflect`
* Added `TypeInfo::docs` method (and similar methods for all info types)
# Objective
- To address problems outlined in https://github.com/bevyengine/bevy/issues/5245
## Solution
- Introduce `reflect(skip_serializing)` on top of `reflect(ignore)` which disables automatic serialisation to scenes, but does not disable reflection of the field.
---
## Changelog
- Adds:
- `bevy_reflect::serde::type_data` module
- `SerializationData` structure for describing which fields are to be/not to be ignored, automatically registers as type_data for struct-based types
- the `skip_serialization` flag for `#[reflect(...)]`
- Removes:
- ability to ignore Enum variants in serialization, since that didn't work anyway
## Migration Guide
- Change `#[reflect(ignore)]` to `#[reflect(skip_serializing)]` where disabling reflection is not the intended effect.
- Remove ignore/skip attributes from enum variants as these won't do anything anymore
# Objective
Fixes#4353. Fixes#4431. Picks up fixes for a panic for `gilrs` when `getGamepads()` is not available.
## Solution
Update the `gilrs` to `v0.9.0`. Changelog can be seen here: dba36f9186
EDIT: Updated `uuid` to 1.1 to avoid duplicate dependencies. Added `nix`'s two dependencies as exceptions until `rodio` updates their deps.
# Objective
Reduce from scratch build time.
## Solution
Reduce the size of the critical path by removing dependencies between crates where not necessary. For `cargo check --no-default-features` this reduced build time from ~51s to ~45s. For some commits I am not completely sure if the tradeoff between build time reduction and convenience caused by the commit is acceptable. If not, I can drop them.
A couple more uncontroversial changes extracted from #3886.
* Enable full feature of syn
It is necessary for the ItemFn and ItemTrait type. Currently it is indirectly
enabled through the tracing dependency of bevy_utils, but this may no
longer be the case in the future.
* Remove unused function from bevy_macro_utils
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.
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
