# Objective
Upgrade to `wgpu` version `25.0`.
Depends on https://github.com/bevyengine/naga_oil/pull/121
## Solution
### Problem
The biggest issue we face upgrading is the following requirement:
> To facilitate this change, there was an additional validation rule put
in place: if there is a binding array in a bind group, you may not use
dynamic offset buffers or uniform buffers in that bind group. This
requirement comes from vulkan rules on UpdateAfterBind descriptors.
This is a major difficulty for us, as there are a number of binding
arrays that are used in the view bind group. Note, this requirement does
not affect merely uniform buffors that use dynamic offset but the use of
*any* uniform in a bind group that also has a binding array.
### Attempted fixes
The easiest fix would be to change uniforms to be storage buffers
whenever binding arrays are in use:
```wgsl
#ifdef BINDING_ARRAYS_ARE_USED
@group(0) @binding(0) var<uniform> view: View;
@group(0) @binding(1) var<uniform> lights: types::Lights;
#else
@group(0) @binding(0) var<storage> view: array<View>;
@group(0) @binding(1) var<storage> lights: array<types::Lights>;
#endif
```
This requires passing the view index to the shader so that we know where
to index into the buffer:
```wgsl
struct PushConstants {
view_index: u32,
}
var<push_constant> push_constants: PushConstants;
```
Using push constants is no problem because binding arrays are only
usable on native anyway.
However, this greatly complicates the ability to access `view` in
shaders. For example:
```wgsl
#ifdef BINDING_ARRAYS_ARE_USED
mesh_view_bindings::view.view_from_world[0].z
#else
mesh_view_bindings::view[mesh_view_bindings::view_index].view_from_world[0].z
#endif
```
Using this approach would work but would have the effect of polluting
our shaders with ifdef spam basically *everywhere*.
Why not use a function? Unfortunately, the following is not valid wgsl
as it returns a binding directly from a function in the uniform path.
```wgsl
fn get_view() -> View {
#if BINDING_ARRAYS_ARE_USED
let view_index = push_constants.view_index;
let view = views[view_index];
#endif
return view;
}
```
This also poses problems for things like lights where we want to return
a ptr to the light data. Returning ptrs from wgsl functions isn't
allowed even if both bindings were buffers.
The next attempt was to simply use indexed buffers everywhere, in both
the binding array and non binding array path. This would be viable if
push constants were available everywhere to pass the view index, but
unfortunately they are not available on webgpu. This means either
passing the view index in a storage buffer (not ideal for such a small
amount of state) or using push constants sometimes and uniform buffers
only on webgpu. However, this kind of conditional layout infects
absolutely everything.
Even if we were to accept just using storage buffer for the view index,
there's also the additional problem that some dynamic offsets aren't
actually per-view but per-use of a setting on a camera, which would
require passing that uniform data on *every* camera regardless of
whether that rendering feature is being used, which is also gross.
As such, although it's gross, the simplest solution just to bump binding
arrays into `@group(1)` and all other bindings up one bind group. This
should still bring us under the device limit of 4 for most users.
### Next steps / looking towards the future
I'd like to avoid needing split our view bind group into multiple parts.
In the future, if `wgpu` were to add `@builtin(draw_index)`, we could
build a list of draw state in gpu processing and avoid the need for any
kind of state change at all (see
https://github.com/gfx-rs/wgpu/issues/6823). This would also provide
significantly more flexibility to handle things like offsets into other
arrays that may not be per-view.
### Testing
Tested a number of examples, there are probably more that are still
broken.

# Objective
- Try to make more of `bevy_color` const now that we have
const_float_arithmetic.
## Solution
Fail abjectly, because of our heavy use of traits.
I did find these functions though, so you can have a PR 🙃
# Objective
Certain classes of games, usually those with enormous worlds, require
some amount of support for double-precision. Libraries like `big_space`
exist to allow for large worlds while integrating cleanly with Bevy's
primarily single-precision ecosystem, but even then, games will often
still work directly in double-precision throughout the part of the
pipeline that feeds into the Bevy interface.
Currently, working with double-precision types in Bevy is a pain. `glam`
provides types like `DVec3`, but Bevy doesn't provide double-precision
analogs for `glam` wrappers like `Dir3`. This is mostly because doing so
involves one of:
- code duplication
- generics
- templates (like `glam` uses)
- macros
Each of these has issues that are enough to be deal-breakers as far as
maintainability, usability or readability. To work around this, I'm
putting together `bevy_dmath`, a crate that duplicates `bevy_math` types
and functionality to allow downstream users to enjoy the ergonomics and
power of `bevy_math` in double-precision. For the most part, it's a
smooth process, but in order to fully integrate, there are some
necessary changes that can only be made in `bevy_math`.
## Solution
This PR addresses the first and easiest issue with downstream
double-precision math support: `VectorSpace` currently can only
represent vector spaces over `f32`. This automatically closes the door
to double-precision curves, among other things. This restriction can be
easily lifted by allowing vector spaces to specify the underlying scalar
field. This PR adds a new trait `ScalarField` that satisfies the
properties of a scalar field (the ones that can be upheld statically)
and adds a new associated type `type Scalar: ScalarField` to
`VectorSpace`. It's mostly an unintrusive change. The biggest annoyances
are:
- it touches a lot of curve code
- `bevy_math::ops` doesn't support `f64`, so there are some annoying
workarounds
As far as curves code, I wanted to make this change unintrusive and
bite-sized, so I'm trying to touch as little code as possible. To prove
to myself it can be done, I went ahead and (*not* in this PR) migrated
most of the curves API to support different `ScalarField`s and it went
really smoothly! The ugliest thing was adding `P::Scalar: From<usize>`
in several places. There's an argument to be made here that we should be
using `num-traits`, but that's not immediately relevant. The point is
that for now, the smallest change I could make was to go into every
curve impl and make them generic over `VectorSpace<Scalar = f32>`.
Curves work exactly like before and don't change the user API at all.
# Follow-up
- **Extend `bevy_math::ops` to work with `f64`.** `bevy_math::ops` is
used all over, and if curves are ever going to support different
`ScalarField` types, we'll need to be able to use the correct `std` or
`libm` ops for `f64` types as well. Adding an `ops64` mod turned out to
be really ugly, but I'll point out the maintenance burden is low because
we're not going to be adding new floating-point ops anytime soon.
Another solution is to build a floating-point trait that calls the right
op variant and impl it for `f32` and `f64`. This reduces maintenance
burden because on the off chance we ever *do* want to go modify it, it's
all tied together: you can't change the interface on one without
changing the trait, which forces you to update the other. A third option
is to use `num-traits`, which is basically option 2 but someone else did
the work for us. They already support `no_std` using `libm`, so it would
be more or less a drop-in replacement. They're missing a couple
floating-point ops like `floor` and `ceil`, but we could make our own
floating-point traits for those (there's even the potential for
upstreaming them into `num-traits`).
- **Tweak curves to accept vector spaces over any `ScalarField`.**
Curves are ready to support custom scalar types as soon as the bullet
above is addressed. I will admit that the code is not as fun to look at:
`P::Scalar` instead of `f32` everywhere. We could consider an alternate
design where we use `f32` even to interpolate something like a `DVec3`,
but personally I think that's a worse solution than parameterizing
curves over the vector space's scalar type. At the end of the day, it's
not really bad to deal with in my opinion... `ScalarType` supports
enough operations that working with them is almost like working with raw
float types, and it unlocks a whole ecosystem for games that want to use
double-precision.
# Objective
There are several uninlined format args (seems to be in more formatting
macros and in more crates) that are not detected on stable, but are on
nightly.
## Solution
Fix them.
# Objective
Colors currently do not implement `StableInterpolate`, which makes them
ineligible for functions like `smooth_nudge` and make some generic APIs
awkward.
## Solution
Implemented `StableInterpolate` for linear color types that should be
uncontroversial. Non-linear types like `Hsl` are not implemented in this
PR.
## Testing
Added a test that checks implementations are correct.
# Objective
Now that #13432 has been merged, it's important we update our reflected
types to properly opt into this feature. If we do not, then this could
cause issues for users downstream who want to make use of
reflection-based cloning.
## Solution
This PR is broken into 4 commits:
1. Add `#[reflect(Clone)]` on all types marked `#[reflect(opaque)]` that
are also `Clone`. This is mandatory as these types would otherwise cause
the cloning operation to fail for any type that contains it at any
depth.
2. Update the reflection example to suggest adding `#[reflect(Clone)]`
on opaque types.
3. Add `#[reflect(clone)]` attributes on all fields marked
`#[reflect(ignore)]` that are also `Clone`. This prevents the ignored
field from causing the cloning operation to fail.
Note that some of the types that contain these fields are also `Clone`,
and thus can be marked `#[reflect(Clone)]`. This makes the
`#[reflect(clone)]` attribute redundant. However, I think it's safer to
keep it marked in the case that the `Clone` impl/derive is ever removed.
I'm open to removing them, though, if people disagree.
4. Finally, I added `#[reflect(Clone)]` on all types that are also
`Clone`. While not strictly necessary, it enables us to reduce the
generated output since we can just call `Clone::clone` directly instead
of calling `PartialReflect::reflect_clone` on each variant/field. It
also means we benefit from any optimizations or customizations made in
the `Clone` impl, including directly dereferencing `Copy` values and
increasing reference counters.
Along with that change I also took the liberty of adding any missing
registrations that I saw could be applied to the type as well, such as
`Default`, `PartialEq`, and `Hash`. There were hundreds of these to
edit, though, so it's possible I missed quite a few.
That last commit is **_massive_**. There were nearly 700 types to
update. So it's recommended to review the first three before moving onto
that last one.
Additionally, I can break the last commit off into its own PR or into
smaller PRs, but I figured this would be the easiest way of doing it
(and in a timely manner since I unfortunately don't have as much time as
I used to for code contributions).
## Testing
You can test locally with a `cargo check`:
```
cargo check --workspace --all-features
```
# Objective
- Allow for convenient access and mutation of color saturation providing
following the `Hue`, `Luminance` traits.
- `with_saturation()` builder method
- `saturation()` to get the saturation of a `Color`
- `set_saturation()` to set the saturation of a mutable `Color`
## Solution
- Defined `Saturation` trait in `color_ops.rs`
- Implemented `Saturation` on `Hsla` and `Hsva`
- Implemented `Saturation` on `Color` which proxies to other color space
impls.
- In the case of colorspaces which don't have native saturation
components
the color is converted to 'Hsla` internally
## Testing
- Empirically tested
---
## Showcase
```rust
fn next_golden(&mut self) -> Color {
self.current
.rotate_hue((1.0 / GOLDEN_RATIO) * 360.0)
.with_saturation(self.rand_saturation())
.with_luminance(self.rand_luminance())
.into()
}
```

## Summary of Changes
### Documentation Indentation
When using lists in documentation, proper indentation is now linted for.
This means subsequent lines within the same list item must start at the
same indentation level as the item.
```rust
/* Valid */
/// - Item 1
/// Run-on sentence.
/// - Item 2
struct Foo;
/* Invalid */
/// - Item 1
/// Run-on sentence.
/// - Item 2
struct Foo;
```
### Implicit `!` to `()` Conversion
`!` (the never return type, returned by `panic!`, etc.) no longer
implicitly converts to `()`. This is particularly painful for systems
with `todo!` or `panic!` statements, as they will no longer be functions
returning `()` (or `Result<()>`), making them invalid systems for
functions like `add_systems`. The ideal fix would be to accept functions
returning `!` (or rather, _not_ returning), but this is blocked on the
[stabilisation of the `!` type
itself](https://doc.rust-lang.org/std/primitive.never.html), which is
not done.
The "simple" fix would be to add an explicit `-> ()` to system
signatures (e.g., `|| { todo!() }` becomes `|| -> () { todo!() }`).
However, this is _also_ banned, as there is an existing lint which (IMO,
incorrectly) marks this as an unnecessary annotation.
So, the "fix" (read: workaround) is to put these kinds of `|| -> ! { ...
}` closuers into variables and give the variable an explicit type (e.g.,
`fn()`).
```rust
// Valid
let system: fn() = || todo!("Not implemented yet!");
app.add_systems(..., system);
// Invalid
app.add_systems(..., || todo!("Not implemented yet!"));
```
### Temporary Variable Lifetimes
The order in which temporary variables are dropped has changed. The
simple fix here is _usually_ to just assign temporaries to a named
variable before use.
### `gen` is a keyword
We can no longer use the name `gen` as it is reserved for a future
generator syntax. This involved replacing uses of the name `gen` with
`r#gen` (the raw-identifier syntax).
### Formatting has changed
Use statements have had the order of imports changed, causing a
substantial +/-3,000 diff when applied. For now, I have opted-out of
this change by amending `rustfmt.toml`
```toml
style_edition = "2021"
```
This preserves the original formatting for now, reducing the size of
this PR. It would be a simple followup to update this to 2024 and run
`cargo fmt`.
### New `use<>` Opt-Out Syntax
Lifetimes are now implicitly included in RPIT types. There was a handful
of instances where it needed to be added to satisfy the borrow checker,
but there may be more cases where it _should_ be added to avoid
breakages in user code.
### `MyUnitStruct { .. }` is an invalid pattern
Previously, you could match against unit structs (and unit enum
variants) with a `{ .. }` destructuring. This is no longer valid.
### Pretty much every use of `ref` and `mut` are gone
Pattern binding has changed to the point where these terms are largely
unused now. They still serve a purpose, but it is far more niche now.
### `iter::repeat(...).take(...)` is bad
New lint recommends using the more explicit `iter::repeat_n(..., ...)`
instead.
## Migration Guide
The lifetimes of functions using return-position impl-trait (RPIT) are
likely _more_ conservative than they had been previously. If you
encounter lifetime issues with such a function, please create an issue
to investigate the addition of `+ use<...>`.

_actually_ changed.

Didn't remove WgpuWrapper. Not sure if it's needed or not still.
## Testing
- Did you test these changes? If so, how? Example runner
- Are there any parts that need more testing? Web (portable atomics
thingy?), DXC.
## Migration Guide
- Bevy has upgraded to [wgpu
v24](https://github.com/gfx-rs/wgpu/blob/trunk/CHANGELOG.md#v2400-2025-01-15).
- When using the DirectX 12 rendering backend, the new priority system
for choosing a shader compiler is as follows:
- If the `WGPU_DX12_COMPILER` environment variable is set at runtime, it
is used
- Else if the new `statically-linked-dxc` feature is enabled, a custom
version of DXC will be statically linked into your app at compile time.
- Else Bevy will look in the app's working directory for
`dxcompiler.dll` and `dxil.dll` at runtime.
- Else if they are missing, Bevy will fall back to FXC (not recommended)

# Objective
- publish script copy the license files to all subcrates, meaning that
all publish are dirty. this breaks git verification of crates
- the order and list of crates to publish is manually maintained,
leading to error. cargo 1.84 is more strict and the list is currently
wrong
## Solution
- duplicate all the licenses to all crates and remove the
`--allow-dirty` flag
- instead of a manual list of crates, get it from `cargo package
--workspace`
- remove the `--no-verify` flag to... verify more things?
# Objective
Fixes#17508
`bevy_color::Color` constructors don't have docs explaining the valid
range for the values passed.
## Solution
I've mostly copied the docs from the respective underlying type's docs,
because that seemed most consistent and accurate.
# Objective
Fixes https://github.com/bevyengine/bevy/issues/17111
## Solution
Move `#![warn(clippy::allow_attributes,
clippy::allow_attributes_without_reason)]` to the workspace `Cargo.toml`
## Testing
Lots of CI testing, and local testing too.

# Objective
I realized that setting these to `deny` may have been a little
aggressive - especially since we upgrade warnings to denies in CI.
## Solution
Downgrades these lints to `warn`, so that compiles can work locally. CI
will still treat these as denies.
# Objective
- Add the original source for Oklab calculations (a blog from the
creator of Oklab) instead of linking to other Rust crates.
## Solution
- Update the links.
Bump version after release

# Objective
- https://github.com/bevyengine/bevy/issues/17111
## Solution
Set the `clippy::allow_attributes` and
`clippy::allow_attributes_without_reason` lints to `deny`, and bring
`bevy_audio` in line with the new restrictions.
No code changes have been made - except if a lint that was previously
`allow(...)`'d could be removed via small code changes. For example,
`unused_variables` can be handled by adding a `_` to the beginning of a
field's name.
## Testing
I ran `cargo clippy`, and received no errors.
# Objective
Remove the reliance on `#[allow(clippy::excessive_precision)]`.
## Solution
Remove the `#[allow(clippy::excessive_precision)]`, and truncate the
float literals to the value rustc would normally truncate them to.
## Testing
I ran `cargo test -p bevy_color`, and received no errors.
# Background
In `no_std` compatible crates, there is often an `std` feature which
will allow access to the standard library. Currently, with the `std`
feature _enabled_, the
[`std::prelude`](https://doc.rust-lang.org/std/prelude/index.html) is
implicitly imported in all modules. With the feature _disabled_, instead
the [`core::prelude`](https://doc.rust-lang.org/core/prelude/index.html)
is implicitly imported. This creates a subtle and pervasive issue where
`alloc` items _may_ be implicitly included (if `std` is enabled), or
must be explicitly included (if `std` is not enabled).
# Objective
- Make the implicit imports for `no_std` crates consistent regardless of
what features are/not enabled.
## Solution
- Replace the `cfg_attr` "double negative" `no_std` attribute with
conditional compilation to _include_ `std` as an external crate.
```rust
// Before
#![cfg_attr(not(feature = "std"), no_std)]
// After
#![no_std]
#[cfg(feature = "std")]
extern crate std;
```
- Fix imports that are currently broken but are only now visible with
the above fix.
## Testing
- CI
## Notes
I had previously used the "double negative" version of `no_std` based on
general consensus that it was "cleaner" within the Rust embedded
community. However, this implicit prelude issue likely was considered
when forming this consensus. I believe the reason why is the items most
affected by this issue are provided by the `alloc` crate, which is
rarely used within embedded but extensively used within Bevy.
# Objective
The rust-versions are out of date.
Fixes#17008
## Solution
Update the values
Cherry-picked from #17006 in case it is controversial
## Testing
Validated locally and in #17006

# Objective
The way `Curve` presently achieves dyn-compatibility involves shoving
`Self: Sized` bounds on a bunch of methods to forbid them from appearing
in vtables. (This is called *explicit non-dispatchability*.) The `Curve`
trait probably also just has way too many methods on its own.
In the past, using extension traits instead to achieve similar
functionality has been discussed. The upshot is that this would allow
the "core" of the curve trait, on which all the automatic methods rely,
to live in a very simple dyn-compatible trait, while other functionality
is implemented by extensions. For instance, `dyn Curve<T>` cannot use
the `Sized` methods, but `Box<dyn Curve<T>>` is `Sized`, hence would
automatically implement the extension trait, containing the methods
which are currently non-dispatchable.
Other motivations for this include modularity and code organization: the
`Curve` trait itself has grown quite large with the addition of numerous
adaptors, and refactoring it to demonstrate the separation of
functionality that is already present makes a lot of sense. Furthermore,
resampling behavior in particular is dependent on special traits that
may be mimicked or analogized in user-space, and creating extension
traits to achieve similar behavior in user-space is something we ought
to encourage by example.
## Solution
`Curve` now contains only `domain` and the `sample` methods.
`CurveExt` has been created, and it contains all adaptors, along with
the other sampling convenience methods (`samples`, `sample_iter`, etc.).
It is implemented for all `C` where `C: Curve<T> + Sized`.
`CurveResampleExt` has been created, and it contains all resampling
methods. It is implemented for all `C` where `C: Curve<T> + ?Sized`.
## Testing
It compiles and `cargo doc` succeeds.
---
## Future work
- Consider writing extension traits for resampling curves in related
domains (e.g. resampling for `Curve<T>` where `T: Animatable` into an
`AnimatableKeyframeCurve`).
- `CurveExt` might be further broken down to separate the adaptor and
sampling methods.
---
## Migration Guide
`Curve` has been refactored so that much of its functionality is now in
extension traits. Adaptors such as `map`, `reparametrize`, `reverse`,
and so on now require importing `CurveExt`, while the resampling methods
`resample_*` require importing `CurveResampleExt`. Both of these new
traits are exported through `bevy::math::curve` and through
`bevy::math::prelude`.
# Objective
Fixes#16104
## Solution
I removed all instances of `:?` and put them back one by one where it
caused an error.
I removed some bevy_utils helper functions that were only used in 2
places and don't add value. See: #11478
## Testing
CI should catch the mistakes
## Migration Guide
`bevy::utils::{dbg,info,warn,error}` were removed. Use
`bevy::utils::tracing::{debug,info,warn,error}` instead.

# Objective
- Remove `derive_more`'s error derivation and replace it with
`thiserror`
## Solution
- Added `derive_more`'s `error` feature to `deny.toml` to prevent it
sneaking back in.
- Reverted to `thiserror` error derivation
## Notes
Merge conflicts were too numerous to revert the individual changes, so
this reversion was done manually. Please scrutinise carefully during
review.
# Objective
- Contributes to #15460
## Solution
- Added the following new features:
- `std` (default)
- `alloc`
- `encase` (default)
- `libm`
## Testing
- Added to `compile-check-no-std` CI command
## Notes
- `ColorCurve` requires `alloc` due to how the underlying `EvenCore`
type works.
- `Srgba::to_hex` requires `alloc` to return a `String`.
- This was otherwise a _very_ simple change
# Objective
MSRV in the standalone crates should be accurate
## Solution
Determine the msrv of each crate and set it
## Testing
Adding better msrv checks to the CI is a next-step.
# Objective
Make the following functions `const` that will be useful to define
colors as constants.
- `Color::srgb_from_array`
- `Color::srgba_u8`
- `Color::srgb_u8`
The last two require Rust 1.82.0.
## Solution
- Make them `const`
- Change MSRV to 1.82.0
## Testing
I tested bevy_color only. My machine does not have enough RAM capacity
to test the whole bevy.
`cargo test -p bevy_color`
# Objective
On HEAD, `bevy_color` does not compile on its own with `--all-features`
enabled. This PR fixes that.
## Solution
- Added the `curve` feature on `bevy_math` to `bevy_color`.
- Added the `serialize` feature on `bevy_math` to
`bevy_color/serialize`.
## Testing
- Compiled with `cargo b -p bevy_color --all-features` on HEAD and on
this PR: it fails to compile on HEAD but compiles with this PR.
# Objective
Currently, sample-interpolated curves (such as those used by the glTF
loader for animations) do unnecessary extra work when `sample_clamped`
is called, since their implementations of `sample_unchecked` are already
clamped. Eliminating this redundant sampling is a small, easy
performance win which doesn't compromise on the animation system's
internal usage of `sample_clamped`, which guarantees that it never
samples curves out-of-bounds.
## Solution
For sample-interpolated curves, define `sample_clamped` in the way
`sample_unchecked` is currently defined, and then redirect
`sample_unchecked` to `sample_clamped`. This is arguably a more
idiomatic way of using the `cores` as well, which is nice.
## Testing
Ran `many_foxes` to make sure I didn't break anything.
# Objective
- Fixes#6370
- Closes#6581
## Solution
- Added the following lints to the workspace:
- `std_instead_of_core`
- `std_instead_of_alloc`
- `alloc_instead_of_core`
- Used `cargo +nightly fmt` with [item level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Item%5C%3A)
to split all `use` statements into single items.
- Used `cargo clippy --workspace --all-targets --all-features --fix
--allow-dirty` to _attempt_ to resolve the new linting issues, and
intervened where the lint was unable to resolve the issue automatically
(usually due to needing an `extern crate alloc;` statement in a crate
root).
- Manually removed certain uses of `std` where negative feature gating
prevented `--all-features` from finding the offending uses.
- Used `cargo +nightly fmt` with [crate level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Crate%5C%3A)
to re-merge all `use` statements matching Bevy's previous styling.
- Manually fixed cases where the `fmt` tool could not re-merge `use`
statements due to conditional compilation attributes.
## Testing
- Ran CI locally
## Migration Guide
The MSRV is now 1.81. Please update to this version or higher.
## Notes
- This is a _massive_ change to try and push through, which is why I've
outlined the semi-automatic steps I used to create this PR, in case this
fails and someone else tries again in the future.
- Making this change has no impact on user code, but does mean Bevy
contributors will be warned to use `core` and `alloc` instead of `std`
where possible.
- This lint is a critical first step towards investigating `no_std`
options for Bevy.

# Objective
- Crate-level prelude modules, such as `bevy_ecs::prelude`, are plagued
with inconsistency! Let's fix it!
## Solution
Format all preludes based on the following rules:
1. All preludes should have brief documentation in the format of:
> The _name_ prelude.
>
> This includes the most common types in this crate, re-exported for
your convenience.
2. All documentation should be outer, not inner. (`///` instead of
`//!`.)
3. No prelude modules should be annotated with `#[doc(hidden)]`. (Items
within them may, though I'm not sure why this was done.)
## Testing
- I manually searched for the term `mod prelude` and updated all
occurrences by hand. 🫠

# Objective
- Currently we have the `ColorRange` trait to interpolate linearly
between two colors
- It would be cool to have:
1. linear interpolation between n colors where `n >= 1`
2. other kinds of interpolation
## Solution
1. Implement `ColorGradient` which takes `n >= 1` colors and linearly
interpolates between consecutive pairs of them
2. Implement `Curve` intergration for this `ColorGradient` which yields
a curve struct. After that we can apply all of the cool curve adaptors
like `.reparametrize()` and `.map()` to the gradient
## Testing
- Added doc tests
- Added tests
## Showcase
```rust
// let gradient = ColorGradient::new(vec![]).unwrap(); // panic! 💥
let gradient = ColorGradient::new([basic::RED, basic::LIME, basic::BLUE]).expect("non-empty");
let curve = gradient.to_curve();
let brighter_curve = curve.map(|c| c.mix(&basic::WHITE, 0.5));
```

# Objective
Fixes#14782
## Solution
Enable the lint and fix all upcoming hints (`--fix`). Also tried to
figure out the false-positive (see review comment). Maybe split this PR
up into multiple parts where only the last one enables the lint, so some
can already be merged resulting in less many files touched / less
potential for merge conflicts?
Currently, there are some cases where it might be easier to read the
code with the qualifier, so perhaps remove the import of it and adapt
its cases? In the current stage it's just a plain adoption of the
suggestions in order to have a base to discuss.
## Testing
`cargo clippy` and `cargo run -p ci` are happy.
Upgrading to WGPU 22.
Needs `naga_oil` to upgrade first, I've got a fork that compiles but
fails tests, so until that's fixed and the crate is officially
updated/released this will be blocked.

# Objective
- Fix issue #2611
## Solution
- Add `--generate-link-to-definition` to all the `rustdoc-args` arrays
in the `Cargo.toml`s (for docs.rs)
- Add `--generate-link-to-definition` to the `RUSTDOCFLAGS` environment
variable in the docs workflow (for dev-docs.bevyengine.org)
- Document all the workspace crates in the docs workflow (needed because
otherwise only the source code of the `bevy` package will be included,
making the argument useless)
- I think this also fixes#3662, since it fixes the bug on
dev-docs.bevyengine.org, while on docs.rs it has been fixed for a while
on their side.

## Changelog
- The source code viewer on docs.rs now includes links to the
definitions.
# Objective
Fix erroneous hue mixing in `Lcha` and `Oklcha`. Purple + Red == Green
is the current behavior.
## Solution
Use `crate::color_ops::lerp_hue` to handle the wrap-around at 360
degrees, the same way that `Hsla`, `Hsva`, and `Hwba` do it.
## Testing
Game jamming, but tested that the workaround below produces
correct-looking colors in my jam game.
# Problem
Division by zero in `crates/bevy_color/src/hsva.rs` when `blackness` is
`1`:
```rust
impl From<Hwba> for Hsva {
fn from(
Hwba {
hue,
whiteness,
blackness,
alpha,
}: Hwba,
) -> Self {
// Based on https://en.wikipedia.org/wiki/HWB_color_model#Conversion
let value = 1. - blackness;
let saturation = 1. - (whiteness / value);
Hsva::new(hue, saturation, value, alpha)
}
}
```
## Solution
With `Hsva` colors if the `value` component is set to `0.` the output
will be pure black regardless of the values of the `hue` or `saturation`
components.
So if `value` is `0`, we don't need to calculate a `saturation` value
and can just set it to `0`:
```rust
impl From<Hwba> for Hsva {
fn from(
Hwba {
hue,
whiteness,
blackness,
alpha,
}: Hwba,
) -> Self {
// Based on https://en.wikipedia.org/wiki/HWB_color_model#Conversion
let value = 1. - blackness;
let saturation = if value != 0. {
1. - (whiteness / value)
} else {
0.
};
Hsva::new(hue, saturation, value, alpha)
}
}
```
