1. Vulkan, Direct3D, Metal, and OpenGL are all native 3D APIs on different platforms. 2. WebGPU is a new 3D API, designed to be used in browsers (but not limited to them) and implemented on top of one or more of the native APIs. 3. wgpu-native is Mozilla's implementation of WebGPU, built in Rust on top of gfx-hal, which is a Rust-specific abstraction on top of native APIs. 3. wgpu-rs is a convenience wrapper to make the API more Rust-like, which either uses wgpu-native directly, or when compiled for a browser, the browser's own WebGPU implementation. 4. Dawn is Google's implementation of WebGPU, in C++, which similarly can be used directly or through a browser.
