Don't know about you, but I consider 3 levels of abstraction a lot, especially when it comes to such black-boxy tech like GPUs. I suspect debugging this Rust code is impossible.

You posted this comment in a browser on an operating system running on at least one CPU using microcode. There are more layers inside those (the OS alone contains a laundry list of abstractions). Three levels of abstractions can be fine.

shader code is not exactly easy to debug for a start...

Debugging the Rust is the easy part. I write vanilla CUDA code that integrates with Rust and that one is the hard part. Abstracting over the GPU backend w/ more Rust isn't a big deal, most of it's SPIR-V anyway. I'm planning to stick with vanilla CUDA integrating with Rust via FFI for now but I'm eyeing this project as it could give me some options for a more maintainable and testable stack.
