simple-wgpu

An opinionated wrapper around wgpu-rs, that aims to improve the API ergonomics and avoid ongoing issues with rust lifetimes.

I'm a big fan of the write-once-cross-compile-anywhere promise underlying WebGPU, but I'm less of a fan of the API itself. The WebGPU API is modelled on an earlier, pipeline-centric vision of the Vulkan API, and has inherited a degree of verbosity/inflexibility as a result. This library aims to recapture some of the simplicity of writing code for OpenGL - ideally without giving up the safety and stability guarantees of wgpu-rs.

Goals

• Reduce the combinatorial pipeline explosion, along the lines of VK_EXT_extended_dynamic_state
• Workaround lifetime limitations while recording render passes in the wgpu-rs rust API
• Improve DRY (Don't Repeat Yourself) by eliminating the duplicate specification in bind group/pipeline layout objects

Non-goals

• Performance. I don't want this wrapper to be slow, but where necessary I will trade performance for ergonomics.
• API Stability (for now). I'm actively iterating on where the boundary between dynamic and baked state should be, as well as whether the more object-oriented wrappers make sense.

Who is it for?

Me, mostly, but if you find it useful, feel free.
