Enum ConnectionError 

pub enum ConnectionError<TransportError> {
    Transport(TransportError),
    UnexpectedEof,
    WriteZero,
    Timeout,
    SequenceExhausted,
    Failed,
}

A terminal failure of a Reliable connection.

Corrupt or malformed frames never produce an error; they are discarded and recovered by retransmission. Once any of these occurs, the connection is permanently failed.

Variants

Transport(TransportError)

The underlying transport returned an error.

UnexpectedEof

The underlying transport reported end of stream.

WriteZero

The underlying transport accepted zero bytes of a nonempty write.

Timeout

A packet went unacknowledged after the configured number of retransmissions.

SequenceExhausted

All 2^32 sequence numbers of this session have been used.

Start a new session with a fresh identifier.

Failed

The connection failed earlier and the original error was already reported.
