如何使用 reST 文档字符串指定可调用参数的返回类型？

Question

Here's a working example with type hinting where I can annotate the parameter that it takes an int and a string and returns a boolean:

from typing import Callable

def func(another_func: Callable[[int, str], bool]):
    pass

The relevant part is -> bool in the picture above. I'm trying to do the same thing with a reStructuredText docstring:

def func2(another_func):
    """ :param function[int, str] another_func: """

This is the closest I've gotten in the picture above. Writing function[[int, str], bool] doesn't work

Change it to just like how PyCharm showed you how it looks like when using typing.Callable :

""" :param (int, str) -> bool another_func: """
