Reasons why a connection might be lost

Variants§

§

VersionMismatch

The peer doesn’t implement any supported version

§

TransportError(Error)

The peer violated the QUIC specification as understood by this implementation

§

ConnectionClosed(ConnectionClose)

The peer’s QUIC stack aborted the connection automatically

§

ApplicationClosed(ApplicationClose)

The peer closed the connection

§

Reset

The peer is unable to continue processing this connection, usually due to having restarted

§

TimedOut

Communication with the peer has lapsed for longer than the negotiated idle timeout

If neither side is sending keep-alives, a connection will time out after a long enough idle period even if the peer is still reachable. See also [TransportConfig::max_idle_timeout()] and [TransportConfig::keep_alive_interval()].

§

LocallyClosed

The local application closed the connection
