Small correction: cuda-oxide does not use `nvcc` to compile Rust kernels.

The device path is roughly: rustc frontend/MIR -> cuda-oxide’s Pliron-based IR/lowering pipeline -> LLVM IR -> PTX via LLVM’s NVPTX backend. Host code still goes through normal rustc/LLVM codegen.

You still need the NVIDIA driver/toolkit pieces to run CUDA code and load PTX on NVIDIA GPUs, so this does not change the broader CUDA ecosystem/dependency story. But it is not “Rust source handed to nvcc”; it is a Rust compiler backend generating device code.
