Enum LossCause 

pub enum LossCause {
    IdleTimeout,
    PeerClosed,
    LocallyClosed,
    Reset,
    TransportError,
}

Why a connection is gone.

The outcome is the same whichever it is — nothing that was in flight completed, which is what Error::ConnectionLost promises — so this is not a second outcome vocabulary. It exists because the next action differs: an idle timeout invites a redial, a peer that closed deliberately may not want one yet, and a local close means the application already decided.

Variants

IdleTimeout

No traffic for the idle period, on whichever side’s timeout was shorter. Nothing is wrong with either peer.

PeerClosed

The peer closed the connection deliberately, with a code this side does not map to a more specific outcome — a shutdown, typically.

LocallyClosed

This side closed it: Runtime::shutdown, or a dropped runtime.

Reset

A stateless reset: the peer has forgotten the connection, usually because it restarted.

TransportError

A QUIC transport error ended the connection. Either peer may be at fault, and a redial is unlikely to behave differently.
