Description:
 def register(self, lookup: Lookup, encoder: Encoder, decoder: Decoder, label: str=None) -> None: """ Registers the given ``encoder`` and ``decoder`` under the given ``lookup``. A unique string label may be optionally provided that can be used to refer to the registration by name. :param lookup: A type string or type string matcher function (predicate). When the registry is queried with a type string ``query`` to determine which encoder or decoder to use, ``query`` will be checked against every registration in the registry. If a registration was created with a type string for ``lookup``, it will be considered a match if ``lookup == query``. If a registration was created with a matcher function for ``lookup``, it will be considered a match if ``lookup(query) is True``. If more than one registration is found to be a match, then an exception is raised. :param encoder: An encoder callable or class to use if ``lookup`` matches a query. If ``encoder`` is a callable, it must accept a python value and return a ``bytes`` value. If ``encoder`` is a class, it must be a valid subclass of :any:`encoding.BaseEncoder` and must also implement the :any:`from_type_str` method on :any:`base.BaseCoder`. :param decoder: A decoder callable or class to use if ``lookup`` matches a query. If ``decoder`` is a callable, it must accept a stream-like object of bytes and return a python value. If ``decoder`` is a class, it must be a valid subclass of :any:`decoding.BaseDecoder` and must also implement the :any:`from_type_str` method on :any:`base.BaseCoder`. :param label: An optional label that can be used to refer to this registration by name. This label can be used to unregister an entry in the registry via the :any:`unregister` method and its variants. """
