Exceptions
==========
MicroPie defines a small number of exceptions. The most commonly
encountered is :class:`~micropie.ConnectionClosed`, used for WebSocket
disconnections.
ConnectionClosed
----------------
.. class:: ConnectionClosed
Raised by :meth:`~micropie.WebSocket.receive_text` and
:meth:`~micropie.WebSocket.receive_bytes` when the client closes
the WebSocket connection. Catch this exception to detect
disconnection and exit your handler gracefully. The exception does
not carry any attributes; the WebSocket connection has already been
closed when it is raised.
