    Create a class that can be passed into `attrs.field`'s ``eq``, ``order``,
    and ``cmp`` arguments to customize field comparison.

    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'.

    See `comparison` for more details.
