Nr r%r%r%r&r?r'rc@r)raU 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.

Nr r%r%r%r&rKr'rc@r)ra 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`.
