Macro cuda_module 

cuda_module!() { /* proc-macro */ }

Compiles CUDA source with nvcc and generates a typed kernel-launch module.

The macro expects a module declaration containing a CUDA source file, exported kernel names, optional header files, and optional compiler arguments:

cuda_module! {
    pub mod kernels {
        source: "kernels/add.cu",
        exports: [add_kernel],
        headers: ["kernels/common.cuh"],
        compile: {
            nvcc_args: ["--std=c++17"],
            nvrtc_args: ["--std=c++17"],
        },
    }
}

Expansion runs nvcc, using the surrounding CUDA environment including CUDA_CCBIN when set, parses the resulting PTX with singe-ptx, and emits a Rust module with a create constructor plus typed wrappers for exported kernels. Syntax errors, missing files, nvcc failures, unsupported PTX, and exports mismatches are reported as compile-time errors.
