Examples

With positional arguments only:

>>> def my_sum(val1:float, val2:float)->float: return val1 + val2
>>> cached_sum = ivy.cache_fn(my_sum)
>>> print(cached_sum(3, 5))
8

With keyword arguments:

>>> def line_eq(x:float, /, *, slp:float=2, itc:float=0)->float: return x*slp+itc
>>> cached_line_eq = ivy.cache_fn(line_eq)
>>> print(cached_line_eq(3, itc=5, slp=2))
