A cross-platform, safe, pure-Rust graphics API.
Wgpu supports now pipeline-overridable constants
This allows you to define constants in wgsl like this:
override some_factor: f32 = 42.1337; // Specifies a default of 42.1337 if it's not set.
And then set them at runtime like so on your pipeline consuming this shader:
// ...
fragment: Some(wgpu::FragmentState {
compilation_options: wgpu::PipelineCompilationOptions {
constants: &[("some_factor".to_owned(), 0.1234)].into(), // Sets `some_factor` to 0.1234.
..Default::default()
},
// ...
}),
// ...

Due to a specification change write_timestamp is no longer supported on WebGPU.
wgpu::CommandEncoder::write_timestamp requires now the new wgpu::Features::TIMESTAMP_QUERY_INSIDE_ENCODERS feature which is available on all native backends but not on WebGPU.

Many numeric built-ins have had a constant evaluation implementation added for them, which allows them to be used in a const context:
abs, acos, acosh, asin, asinh, atan, atanh, cos, cosh, round, saturate, sin, sinh, sqrt, step, tan, tanh, ceil, countLeadingZeros, countOneBits, countTrailingZeros, degrees, exp, exp2, floor, fract, fma, inverseSqrt, log, log2, max, min, radians, reverseBits, sign, trunc

The following subgroup operations are available in wgsl now:
subgroupBallot, subgroupAll, subgroupAny, subgroupAdd, subgroupMul, subgroupMin, subgroupMax, subgroupAnd, subgroupOr, subgroupXor, subgroupExclusiveAdd, subgroupExclusiveMul, subgroupInclusiveAdd, subgroupInclusiveMul, subgroupBroadcastFirst, subgroupBroadcast, subgroupShuffle, subgroupShuffleDown, subgroupShuffleUp, subgroupShuffleXor
Availability is governed by the following feature flags:
wgpu::Features::SUBGROUP for all operations except subgroupBarrier in fragment & compute, supported on Vulkan, DX12 and Metal.wgpu::Features::SUBGROUP_VERTEX, for all operations except subgroupBarrier general operations in vertex shaders, supported on Vulkanwgpu::Features::SUBGROUP_BARRIER, for support of the subgroupBarrier operation, supported on Vulkan & MetalNote that there currently some differences between wgpu's native-only implementation and the open WebGPU proposal.

web_sys--cfg=web_sys_unstable_apis is no longer needed in your RUSTFLAGS to compile for WebGPU!!!
While WebGPU's javascript api is stable in the browsers, the web_sys bindings for WebGPU are still improving. As such they are hidden behind the special cfg --cfg=web_sys_unstable_apis and are not available by default. Everyone who wanted to use our WebGPU backend needed to enable this cfg in their RUSTFLAGS. This was very inconvenient and made it hard to use WebGPU, especially when WebGPU is enabled by default. Additionally, the unstable APIs don't adhere to semver, so there were repeated breakages.
To combat this problem we have decided to vendor the web_sys bindings for WebGPU within the crate. Notably we are not forking the bindings, merely vendoring, so any improvements we make to the bindings will be contributed directly to upstream web_sys.

All of wgpu's public dependencies are now re-exported at the top level so that users don't need to take their own dependencies. This includes:
Enabling webgl no longer removes the webgpu backend.
Instead, there's a new (default enabled) webgpu feature that allows to explicitly opt-out of webgpu if so desired.
If both webgl & webgpu are enabled, wgpu::Instance decides upon creation whether to target wgpu-core/WebGL or WebGPU.
This means that adapter selection is not handled as with regular adapters, but still allows to decide at runtime whether
webgpu or the webgl backend should be used using a single wasm binary.

It is now possible to safely create a wgpu::Surface with wgpu::Instance::create_surface() by letting wgpu::Surface hold a lifetime to window.
Passing an owned value window to Surface will return a wgpu::Surface<'static>.
All possible safe variants (owned windows and web canvases) are grouped using wgpu::SurfaceTarget.
Conversion to wgpu::SurfaceTarget is automatic for any type implementing raw-window-handle's HasWindowHandle & HasDisplayHandle traits, i.e. most window types.
For web canvas types this has to be done explicitly:
let surface: wgpu::Surface<'static> = instance.create_surface(wgpu::SurfaceTarget::Canvas(my_canvas))?;
All unsafe variants are now grouped under wgpu::Instance::create_surface_unsafe which takes the
wgpu::SurfaceTargetUnsafe enum and always returns wgpu::Surface<'static>.
In order to create a wgpu::Surface<'static> without passing ownership of the window use
wgpu::SurfaceTargetUnsafe::from_window:
let surface = unsafe {
instance.create_surface_unsafe(wgpu::SurfaceTargetUnsafe::from_window(&my_window))?
};
The easiest way to make this code safe is to use shared ownership:
let window: Arc<winit::Window>;
// ...
let surface = instance.create_surface(my_window.clone())?;
All platform specific surface creation using points have moved into SurfaceTargetUnsafe as well.
For example:
Safety by @daxpedda in #4597 Unification by @wumpf in #4984
Abstract types make numeric literals easier to use, by automatically converting literals and other constant expressions from abstract numeric types to concrete types when safe and necessary. For example, to build a vector of floating-point numbers, Naga previously made you write:
vec3<f32>(1.0, 2.0, 3.0)
With this change, you can now simply write:
vec3<f32>(1, 2, 3)
Even though the literals are abstract integers, Naga recognizes
that it is safe and necessary to convert them to f32 values in
order to build the vector. You can also use abstract values as
initializers for global constants and global and local variables,
like this:
var unit_x: vec2<f32> = vec2(1, 0);
The literals 1 and 0 are abstract integers, and the expression
vec2(1, 0) is an abstract vector. However, Naga recognizes that
it can convert that to the concrete type vec2<f32> to satisfy
the given type of unit_x.
The WGSL specification permits abstract integers and
floating-point values in almost all contexts, but Naga's support
for this is still incomplete. Many WGSL operators and builtin
functions are specified to produce abstract results when applied
to abstract inputs, but for now Naga simply concretizes them all
before applying the operation. We will expand Naga's abstract type
support in subsequent pull requests.
As part of this work, the public types naga::ScalarKind and
naga::Literal now have new variants, AbstractInt and AbstractFloat.
By @jimblandy in #4743, #4755.
Instance::enumerate_adapters now returns Vec<Adapter> instead of an ExactSizeIteratorThis allows us to support WebGPU and WebGL in the same binary.
- let adapters: Vec<Adapter> = instance.enumerate_adapters(wgpu::Backends::all()).collect();
+ let adapters: Vec<Adapter> = instance.enumerate_adapters(wgpu::Backends::all());
By @wumpf in #5044
device.poll() now returns a MaintainResult instead of a boolThis is a forward looking change, as we plan to add more information to the MaintainResult in the future.
This enum has the same data as the boolean, but with some useful helper functions.
- let queue_finished: bool = device.poll(wgpu::Maintain::Wait);
+ let queue_finished: bool = device.poll(wgpu::Maintain::Wait).is_queue_empty();

This allows us to cover the last 12 years of Intel GPUs (starting with Ivy Bridge; aka 3xxx), and the last 16 years of AMD (starting with Terascale; aka HD 2000) / NVidia GPUs (starting with Tesla; aka GeForce 8xxx).

By @FL33TW00D & @wumpf in #3636.
We now support binary occlusion queries! This allows you to determine if any of the draw calls within the query drew any pixels.
Use the new occlusion_query_set field on RenderPassDescriptor to give a query set that occlusion queries will write to.
let mut rpass = encoder.begin_render_pass(&wgpu::RenderPassDescriptor {
// ...
+ occlusion_query_set: Some(&my_occlusion_query_set),
});
Within the renderpass do the following to write the occlusion query results to the query set at the given index:
rpass.begin_occlusion_query(index);
rpass.draw(...);
rpass.draw(...);
rpass.end_occlusion_query();
These are binary occlusion queries, so the result will be either 0 or an unspecified non-zero value.
