ConnectionError

Enum ConnectionError

pub enum ConnectionError {
    VersionMismatch,
    TransportError(Error),
    ConnectionClosed(ConnectionClose),
    ApplicationClosed(ApplicationClose),
    Reset,
    TimedOut,
    LocallyClosed,
    CidsExhausted,
}

Available on crate features quic and std only.

Expand description

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

The handshake deadline or negotiated idle timeout elapsed.

The local handshake deadline also applies when idle timeout is disabled. After connecting, a long enough idle period can time out even if the peer is still reachable. See TransportConfig::set_max_idle_timeout and TransportConfig::set_keep_alive_interval.

LocallyClosed

The local application closed the connection

CidsExhausted

The connection could not be created because not enough of the CID space is available

Try using longer connection IDs.
