sndata.utils.wrappers.lru_copy_cache(maxsize: int = 128, typed: bool = False, copy: bool = True)

Decorator to cache the return of a function

Similar to functools.lru_cache, but allows a copy of the cached value to be returned, thus preventing mutation of the cache.

Parameters:

• maxsize – Maximum size of the cache
• typed – Cache objects of different types separately (Default: False)
• copy – Return a copy of the cached item (Default: True)

Returns:

A decorator
