Comment from 10 Sep 2026 in “Rust is tier-1 language at Microsoft” Good fit for existing CUDA kernels
“If your workflow is "I already have CUDA C++/PTX/CUBIN kernels and want to call them from Rust", cudarc is a very natural fit.”
Comment from 12 May 2026 in “CUDA-oxide: Nvidia's official Rust to CUDA compiler” “then cudarc is probably the better option”
