joblib: load all cached values (or search through all of them)

  joblib, python

Using joblib.Memory I can cache the results of some function, but I wonder if there is an efficient way to figure out the list of arguments for which there is a cached value.

For example, suppose that the function slow_func was computed and cached for some values of x, can I find out for which values I have cache?

from joblib import Memory
mem = Memory(location='cache')

def slow_func(x):
    return x
