JSON Schema does not mandate that the ``format`` property actually do any validation. If validation is desired however, instances of this class can be hooked into validators to enable format validation. :class:`FormatChecker` objects always return ``True`` when asked about formats that they do not know how to validate. To check a custom format using a function that takes an instance and returns a ``bool``, use the :meth:`FormatChecker.checks` or :meth:`FormatChecker.cls_checks` decorators. Arguments: formats (iterable): The known formats to validate. This argument can be used to limit which formats will be used during validation.

Arguments: format (str): The format that the decorated function will check. raises (Exception): The exception(s) raised by the decorated function when an invalid instance is found.
