wgpu-rs is an idiomatic Rust wrapper over [wgpu-core](https://github.com/gfx-rs/wgpu). It's designed to be suitable for general purpose graphics and computation needs of Rust community.

Currently wgpu-rs works on native platforms, but [WASM support is currently being added](https://github.com/gfx-rs/wgpu-rs/issues/101) as well.

## Usage

### How to Run Examples

All examples are located under the [examples](examples) directory.

These examples use the default syntax for running examples, as found in the [Cargo](https://doc.rust-lang.org/cargo/reference/manifest.html#examples) documentation. For example, to run the `cube` example:

```bash
cargo run --example cube
```

The `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:

```bash
cargo run --example hello-compute 1 2 3 4
```

## Development

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":

```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 to do `cargo update -p gfx-backend-dx12`.
