wgpu-rs is an idiomatic Rust wrapper over wgpu-core. It's designed to be suitable for general purpose graphics and computation needs of Rust community.
wgpu-rs can target both the natively supported backends and WASM directly.
All examples are located under the examples directory.
These examples use the default syntax for running examples, as found in the Cargo documentation. For example, to run the cube example:
cargo run --example cubeThe hello-triangle and hello-compute examples show bare-bones setup without any helper code. For hello-compute, pass 4 numbers separated by spaces as arguments:
cargo run --example hello-compute 1 2 3 4Running on the web is still work-in-progress. You may need to enable experimental flags on your browser. Check browser implementation status on webgpu.io.
To run examples on the wasm32-unknown-unknown target, first build the example as usual, then run wasm-bindgen:
# Install or update wasm-bindgen-cli
cargo install -f wasm-bindgen-cli
# Build with the wasm target
RUSTFLAGS=--cfg=web_sys_unstable_apis cargo build --target wasm32-unknown-unknown --example hello-triangle
# Generate bindings in a `target/generated` directory
wasm-bindgen --out-dir target/generated --web target/wasm32-unknown-unknown/debug/examples/hello-triangle.wasmCreate an index.html file into target/generated directory and add the following code:
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<script type="module">
import init from "./hello-triangle.js";
init();
</script>
</body>
</html>Now run a web server locally inside the target/generated directory to see the hello-triangle in the browser.
e.g. python -m http.server

Also, libraries that have support for wgpu-rs:
If you need to test local fixes to gfx-rs or other dependencies, the simplest way is to add a Cargo patch. For example, when working on DX12 backend on Windows, you can check out the "hal-0.2" branch of gfx-rs repo and add this to the end of "Cargo.toml":
[patch.crates-io]
gfx-backend-dx12 = { path = "../gfx/src/backend/dx12" }
gfx-hal = { path = "../gfx/src/hal" }If a version needs to be changed, you need to do cargo update -p gfx-backend-dx12.
