Expand description

Reasons why a connection might be lost

Variants

`VersionMismatch`

The peer doesn’t implement any supported version

`TransportError(TransportError)`

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
