Raised when trying to interact with a closed connection.
Attributes:
rcvd: If a close frame was received, its code and reason are available
in ``rcvd.code`` and ``rcvd.reason``.
sent: If a close frame was sent, its code and reason are available
in ``sent.code`` and ``sent.reason``.
rcvd_then_sent: If close frames were received and sent, this attribute
tells in which order this happened, from the perspective of this
side of the connection.

Raised when receiving or sending a frame that breaks the protocol.

* receiving or sending a frame that contains invalid data;
* receiving or sending an invalid sequence of frames.

Raised when parsing a frame with a payload that exceeds the maximum size.
The Sans-I/O layer uses this exception internally. It doesn't bubble up to
the I/O layer.
The :meth:`~websockets.extensions.Extension.decode` method of extensions
must raise :exc:`PayloadTooBig` if decoding a frame would exceed the limit.

Raised when sending a frame is forbidden in the current state.
Specifically, the Sans-I/O layer raises this exception when:
* sending a data frame to a connection in a state other
:attr:`~websockets.protocol.State.OPEN`;
* sending a control frame to a connection in a state other than
:attr:`~websockets.protocol.State.OPEN` or
:attr:`~websockets.protocol.State.CLOSING`.
Nr r% r% r% r& r � r' r c @ r )r z�
Raised when receiving or sending messages concurrently.
WebSocket is a connection-oriented protocol. Reads must be serialized; so
must be writes. However, reading and writing concurrently is possible.
