You can write a #[cuda] proc macro that: - parses the Rust AST - folds it into a CUDA C AST - writes it to a temporary .cu file - compiles it with nvcc - links it into your Rust binary and that allows you to launch your function as a CUDA kernel. The Rust emu crate does this (more or less), but targets WebGPU instead of CUDA.
