rxn.utilities.caching.cached_on_disk(func)[source]

Decorator for function cache relying on the disk.

Useful when functools.cache() or functools.lru_cache() cannot be used because of threads (especially in celery workers).

Simplifies the syntax compared to relying on diskcache only.

Note that diskcache makes a difference between args and kwargs, i.e. calling a function one time by argument and one time by keyword argument will lead to the wrapped function body being executed two times.

Examples

>>> @cached_on_disk
... def foo(bar: str) -> str:
...     # ...

Parameters: func (Callable[[ParamSpec], TypeVar(ReturnType)]) –
Return type: Callable[[ParamSpec], TypeVar(ReturnType)]
