# picklecachefun

Cache the results of function calls to disk, using pickle, similarly to `functools.cache` in the standard library.

## Example usage

Basic use:

```python

import picklecachefun

@picklecachefun.cache('/path/to/filename.pkl')

def some_function(some_arg):

    ....

    return stuff

```

A default cache root can be set too:

```python

picklecachefun.set_cache_root('/path/to/cache')

@picklecachefun.cache('filename.pkl')

...

```

The cache can be invalidated through setting a `min_time`.

In short, set the `min_time` to the timestamp of 

when you most recently changed the function definition and need

to invalidate the cache.

```python

@picklecachefun.cache('filename.pkl', min_time="2023-12-04T20:56:48")

...

```
