The resulting class will have a full set of ordering methods if at least one of ``{lt, le, gt, ge}`` and ``eq`` are provided. :param Optional[callable] eq: `callable` used to evaluate equality of two objects. :param Optional[callable] lt: `callable` used to evaluate whether one object is less than another object. :param Optional[callable] le: `callable` used to evaluate whether one object is less than or equal to another object. :param Optional[callable] gt: `callable` used to evaluate whether one object is greater than another object. :param Optional[callable] ge: `callable` used to evaluate whether one object is greater than or equal to another object. :param bool require_same_type: When `True`, equality and ordering methods will return `NotImplemented` if objects are not of the same type. :param Optional[str] class_name: Name of class. Defaults to 'Comparable'.
