[docs]class MessagePackHandler(BaseHandler): """Handler built using the :py:mod:`msgpack` module. This handler uses ``msgpack.unpackb()`` and ``msgpack.packb()``. The MessagePack ``bin`` type is used to distinguish between Unicode strings (``str`` on Python 3, ``unicode`` on Python 2) and byte strings (``bytes`` on Python 2/3, or ``str`` on Python 2). Note: This handler requires the extra ``msgpack`` package, which must be installed in addition to ``falcon`` from PyPI: .. code:: $ pip install msgpack Python 2.6 users will need to use the deprecated ``msgpack-python`` package instead, pinned to version 0.4.8.
