 wgpu-rs is aiming to be a safe, portable API which reduces the complexity of working with low-level graphics APIs. It has a layered implementation:
 
-- The `wgpu-native` layer which exposes a C API. `wgpu-native` implemented on top of gfx-hal which allows it to work with the same platforms that gfx-hal already supports. The idea is that `wgpu-native` will have a compatible C API with Google's [Dawn](https://dawn.googlesource.com/daw) implementation so they can be used interchangeably for applications compiled in other languages.

 - The `wgpu-rs` layer which is an idiomatic safe Rust API. It uses `wgpu-native` internally when targetting the native targets. It will use Web APIs (from WASM host bindings) directly when targetting the Web in the future.
 
 Let's dive into the mentioned qualities of the API:
