Variants

Timeout

The dispatcher timer has expired.

WriteBackpressure

Write backpressure is currently active.

PeerGone(Option<Error>)

The connection is no longer usable.

Reported once the connection can no longer dispatch frames, whether because transport shutdown has begun, the peer disconnected, an error occurred, or shutdown was started locally with IoRef::close or IoRef::terminate. The transport backend may still be finishing teardown.

Carries the connection error, which may originate from the transport, a filter, or shutdown. None means no error was recorded.
