5"""Persistent program cache for cuda.core. 

6 

7Public surface: 

8 

9* :class:`ProgramCacheResource` -- bytes-in / bytes-out ABC. 

10* :class:`InMemoryProgramCache` -- thread-safe LRU dict-backed cache. 

11* :class:`FileStreamProgramCache` -- atomic, multi-process directory cache. 

12* :func:`make_program_cache_key` -- key derivation for arbitrary 

13 ``Program`` configurations. 

14 

15The package is split into submodules by concern. Tests that need to 

16monkeypatch internals (Windows flag, version probes, helpers, ...) 

17should reach into the owning submodule (e.g. 

18``_program_cache._file_stream._IS_WINDOWS``, 

19``_program_cache._keys._linker_backend_and_version``) rather than the 

20package object: the symbols re-exported here are only convenience 

21aliases and don't intercept calls within the submodules.
