[![Build Status](https://github.com/gfx-rs/wgpu/workflows/CI/badge.svg)](https://github.com/gfx-rs/wgpu/actions)
[![codecov.io](https://codecov.io/gh/gfx-rs/wgpu/branch/master/graph/badge.svg?token=84qJTesmeS)](https://codecov.io/gh/gfx-rs/wgpu)
This is the core logic of an experimental [WebGPU](https://www.w3.org/community/gpu/) implementation. It's written in Rust and is based on [gfx-hal](https://github.com/gfx-rs/gfx) with help of [gpu-alloc](https://github.com/zakarumych/gpu-alloc) and [gpu-descriptor](https://github.com/zakarumych/gpu-descriptor). See the upstream [WebGPU specification](https://gpuweb.github.io/gpuweb/) (work in progress).
This is an implementation of [WebGPU](https://www.w3.org/community/gpu/) API in Rust, targeting both native and the Web.

See the upstream [WebGPU specification](https://gpuweb.github.io/gpuweb/) (work in progress).
The implementation consists of the following parts:
