258: Run-time lock protection against double root r=grovesNL a=kvark Fixes https://github.com/gfx-rs/wgpu-rs/issues/42 cc @paulkernfeld We didn't handle a case where the root locking token would get dropped (while some children are borrowed), and a new one is created. This was the case in `wgpu_device_poll`, which ended up trying to unmap the buffers. This PR brings a relatively simple run-time check for this. It could *probably* be done at the type level, but I'm going to leave it for any follow ups (help is welcome!), because: 1. we'll still have a run-time check for the simple case where 2 or more root tokens are created 2. I spent 20 minutes trying and wasn't able to get this going Co-authored-by: Dzmitry Malyshau <kvarkus@gmail.com>
This is an active GitHub mirror of the WebGPU native implementation in Rust, which now lives in Mozilla-central. Issues and pull requests are accepted, but we merge them in m-c manually and then sync to GitHub instead of landing directly here.
WebGPU
This is an experimental WebGPU implementation as a native static library. It's written in Rust and is based on gfx-hal and Rendy libraries. The corresponding WebIDL specification can be found at gpuweb project.
The implementation consists of the following parts:
wgpu-native- the native implementation of WebGPU as a C API librarywgpu-remote- remoting layer to work with WebGPU across the process boundaryffi- the C headers generated by cbindgen for both of the libraries
Supported platforms:
- Vulkan on Windows and Linux
- D3D12 and D3D11 on Windows
- Metal on macOS and iOS
Usage
This repository contains C-language examples that link to the native library targets and perform basic rendering and computation. To run the C triangle example, install a C compiler + glfw 3, then run these commands at the root of the repo:
rustup toolchain install nightly
cargo install cbindgen
make examples-native
cd examples/hello_triangle_c/build
./hello_triangle
The idiomatic Rust wrapper lives in https://github.com/gfx-rs/wgpu-rs and provides a number of more complex examples to get a feel of the API.
