Module module 

ModuleActor — load prebuilt cubin/PTX from disk (or memory) and launch its kernels.

Distinct from crate::kernel::nvrtc / NvrtcActor, which JIT-compiles CUDA C++ at runtime. This actor is for the “ahead-of-time-compiled, ship-the-bytes” workflow.

Lifecycle:

1. LoadCubin { bytes } or LoadPtx { src } → returns a ModuleHandle.
2. GetFunction { handle, name } → returns a FunctionHandle.
3. Launch { function, cfg, args } → enqueues a kernel call on the actor’s stream and replies after stream completion.
4. LaunchCooperative { function, cfg, args } → same but goes through cuLaunchCooperativeKernel. Required for cluster / grid-sync kernels (Hopper SM90+).
5. Unload { handle } → frees the CUmodule.

KernelArg is re-exported from crate::kernel::nvrtc so this actor and NvrtcActor share one launch-arg type.

Re-exports

pub use crate::kernel::nvrtc::KernelArg;

Opaque module handle. Carries an internal id used by the actor’s internal HashMap.
