59: Map buffers async r=kvark a=swiftcoder This is not ready to merge. It works well enough for the example, but looking for some early feedback. In particular: - It's not really async, since gfx-hal's mapping APIs seem to all be immediate. - Async callbacks in Rust are really unpleasant due to lifetimes, so maybe it's just as well they aren't async. - There is no validation and no real error handling here yet.

WebGPU
This is an experimental WebGPU implementation as a native static library. It's written in Rust and is based on gfx-hal and satellite 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-bindings- automatic generator of actual C headerswgpu-remote- remoting layer to work with WebGPU across the process boundarywgpu-rs- idiomatic Rust wrapper of the native library
Example
To run an example, simply cd to the examples or gfx-examples directory, then use cargo run with --features {backend} to specify the backend (where {backend} is either vulkan, dx12, dx11 or metal). For example:
# Clone the wgpu repository
git clone https://github.com/gfx-rs/wgpu
# Change directory to `examples`
cd wgpu/examples
# Vulkan (Linux/Windows)
cargo run --bin hello_triangle --features vulkan
# Metal (macOS/iOS)
cargo run --bin hello_triangle --features metal
# DirectX12 (Windows)
cargo run --bin hello_triangle --features dx12
cd ../gfx-examples
# Vulkan (Linux/Windows)
cargo run --bin cube --features vulkan
# Metal (macOS/iOS)
cargo run --bin cube --features metal
# DirectX12 (Windows)
cargo run --bin cube --features dx12
These examples assume that necessary dependencies for the graphics backend are already installed. For more information about installation and usage, refer to the Getting Started guide.
