769: Implement and Validate all WebGPU Limits r=kvark a=cwfitzgerald **Connections** None? **Description** This adds all the limits that webgpu has currently. It also validates the values. The main piece of code here is `BindingTypeMaxCountValidator` and `PerStageBindingTypeCounter` which provides the interface for figuring out the maximum per-stage counts in the pipeline. For each `BindGroupLayout` a `BindingTypeMaxCountValidator`is put together during creation using all of the bindings. Then the `BindingTypeMaxCountValidator`s are combined into a single max. This is then validated against the max limits. Each commit should be independently testable and are grouped by responsibility. **Testing** I modified the wgpu-rs example framework to ask for extremely reduced limits and then tested various examples to verify it properly accepted/rejected based on the actual limit.

This is an active GitHub mirror of the WebGPU implementation in Rust, which now lives in "gfx/wgpu" of Mozilla-central. Issues and pull requests are accepted, but some bidirectional synchronization may be involved.
WebGPU
This is the core logic of an experimental WebGPU implementation. It's written in Rust and is based on gfx-hal with help of gfx-extras. See the upstream WebGPU specification (work in progress).
The implementation consists of the following parts:
- internal Rust API for WebGPU implementations to use
- Rust types shared between wgpu-core,wgpu-native, andwgpu-rsplayer- standalone application for replaying the API traces, useswinit
This repository contains the core of wgpu, and is not usable directly by applications.
If you are looking for the user-facing Rust API, you need wgpu-rs.
If you are looking for the native implementation or bindings to the API in other languages, you need wgpu-native.
