Classes

Checking a class docstring is not enabled by default, as this check is opinionated, and won’t suite everyone

This check will check documentation of __init__ under the class docstring, and not under __init__ itself

>>> string = """
... class Klass:
...     '''Summary for failing docstring...
...
...     Explanation for failing docstring...
...
...     :param param1: About param1.
...     :param param2: About param2.
...     :param param3: About param3.
...     '''
...     def __init__(self, param1, param2) -> None:
...         pass
... """
>>> docsig(string=string, check_class=True)
