Module registry 

2026-09-25: MetraleRegistry: one model’s kernel modules, loaded into the process CUDA context, with raw driver-API helpers for launches, copies and device symbols.

Owner: gpu-runtime. Invariants:

• Each raw handle in raw_modules is a view of the cudarc module stored under the same name in modules; unload_raw drains both maps together.
• A registry owns neither the context nor the stream; both belong to the process-scoped CudaHost.

Re-exports

Structs

MetraleRegistry

2026-09-25: The kernel modules of one loaded model.

RawCudaFunc

2026-09-25: A raw CUfunction handle from MetraleRegistry::raw_function_cached.

Constants

CUDA_ERROR_DEINITIALIZED

2026-09-25: CUDA_ERROR_DEINITIALIZED: the driver has already shut down. The free paths treat it as nothing to do (see is_teardown_noop).

Functions

cuda_error_text

2026-09-25: Format a CUresult as "<NAME> (<status>): <description>", with CUDA_UNKNOWN and (no message) when the driver has no name or string for it.

is_teardown_noop

2026-09-25: Whether a CUresult means the context is already gone, so there is nothing to free: CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_INVALID_CONTEXT (201) or CUDA_ERROR_CONTEXT_IS_DESTROYED (709).
