The Rise of Wgpu

What didn’t go entirely smoothly was the integration into Rust ecosystem: building libraries and applications on top of gfx’s hardware abstraction layer (hal) proved to be extremely challenging due to the low-levelness and unsafety of the API. Coincidentally, these are qualities we are currently missing in the gfx-rs ecosystem: security means safety (in the Rust sense), and portability means that people can use it and run everywhere, without worrying about thousands of potential configurations at run-time, or diverging behavior between platforms due to timing differences or loosely defined behavior. The code runs on a variety of platforms from a single source: Vulkan, Metal, D3D12/D3D11, and eventually the Web (when the browsers gain support for the API, which is also in our scope of work).
