Module program 

Compiled kernel programs.

Traits

ArgVisitor

Receives each argument of a kernel in order. Implement this on a backend- specific “packer” struct (e.g. a CUDA arg-pointer array builder).

Kernel

A kernel definition: its source, name, and identity.

KernelArg

Implemented by each concrete argument type; dispatches to the right ArgVisitor method.

KernelArgs

Implemented for tuples of KernelArgs; visits each element in order. The proc macro generates type Args<'a> = (A, B, C, ...) and the blanket tuple impls below make that satisfy this bound automatically.

Program

A kernel K compiled and loaded onto a device, ready to launch.
