Updates the requirements on wgpu-types to permit the latest version.

Release notes

Sourced from wgpu-types's releases.

v22.0.0 (Our first major version release!)

Our first major version release!

For the first time ever, WGPU is being released with a major version (i.e., 22.* instead of 0.22.*)! Maintainership has decided to fully adhere to Semantic Versioning's recommendations for versioning production software. According to SemVer 2.0.0's Q&A about when to use 1.0.0 versions (and beyond):

How do I know when to release 1.0.0?

If your software is being used in production, it should probably already be 1.0.0. If you have a stable API on which users have come to depend, you should be 1.0.0. If you’re worrying a lot about backward compatibility, you should probably already be 1.0.0.

It is a well-known fact that WGPU has been used for applications and platforms already in production for years, at this point. We are often concerned with tracking breaking changes, and affecting these consumers' ability to ship. By releasing our first major version, we publicly acknowledge that this is the case. We encourage other projects in the Rust ecosystem to follow suit.

Note that while we start to use the major version number, WGPU is not "going stable", as many Rust projects do. We anticipate many breaking changes before we fully comply with the WebGPU spec., which we expect to take a small number of years.

Overview

A major (pun intended) theme of this release is incremental improvement. Among the typically large set of bug fixes, new features, and other adjustments to WGPU by the many contributors listed below, @​wumpf and @​teoxoy have merged a series of many simplifications to WGPU's internals and, in one case, to the render and compute pass recording APIs. Many of these change WGPU to use atomically reference-counted resource tracking (i.e., Arc<…>), rather than using IDs to manage the lifetimes of platform-specific graphics resources in a registry of separate reference counts. This has led us to diagnose and fix many long-standing bugs, and net some neat performance improvements on the order of 40% or more of some workloads.

While the above is exciting, we acknowledge already finding and fixing some (easy-to-fix) regressions from the above work. If you migrate to WGPU 22 and encounter such bugs, please engage us in the issue tracker right away!

Major Changes

Lifetime bounds on wgpu::RenderPass & wgpu::ComputePass

wgpu::RenderPass & wgpu::ComputePass recording methods (e.g. wgpu::RenderPass:set_render_pipeline) no longer impose a lifetime constraint to objects passed to a pass (like pipelines/buffers/bindgroups/query-sets etc.).

This means the following pattern works now as expected:

let mut pipelines: Vec<wgpu::RenderPipeline> = ...;
// ...
let mut cpass = encoder.begin_compute_pass(&wgpu::ComputePassDescriptor::default());
cpass.set_pipeline(&pipelines[123]);
// Change pipeline container - this requires mutable access to `pipelines` while one of the pipelines is in use.
pipelines.push(/* ... */);
// Continue pass recording.
cpass.set_bindgroup(...);

Previously, a set pipeline (or other resource) had to outlive pass recording which often affected wider systems, meaning that users needed to prove to the borrow checker that Vec<wgpu::RenderPipeline> (or similar constructs) aren't accessed mutably for the duration of pass recording.

Furthermore, you can now opt out of wgpu::RenderPass/wgpu::ComputePass's lifetime dependency on its parent wgpu::CommandEncoder using wgpu::RenderPass::forget_lifetime/wgpu::ComputePass::forget_lifetime:

fn independent_cpass<'enc>(encoder: &'enc mut wgpu::CommandEncoder) -> wgpu::ComputePass<'static> {
    let cpass: wgpu::ComputePass<'enc> = encoder.begin_compute_pass(&wgpu::ComputePassDescriptor::default());
    cpass.forget_lifetime()
}

⚠️ As long as a wgpu::RenderPass/wgpu::ComputePass is pending for a given wgpu::CommandEncoder, creation of a compute or render pass is an error and invalidates the wgpu::CommandEncoder.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
