Enum C2ConnectionLossReason 

pub enum C2ConnectionLossReason {
    PipeClosed,
    Protocol,
    RegularEventBackpressure,
    Shutdown,
}

Why control_owner tore its connection down, attached to every request still pending at that moment (C2ControlError::ConnectionLost). Logged once at the teardown point instead of being silently swallowed.

Variants

PipeClosed

The reader or writer half of the physical pipe ended (I/O error, EOF, or a downstream send failure into the writer task).

Protocol

The relay sent a frame or reply that violates the negotiated protocol: an unmatched request id, a route/incarnation mismatch, an unnegotiated-capability leak, an invalid topology frame, or a repeated handshake frame after authentication.

RegularEventBackpressure

The regular event consumer is gone: its channel closed because the receiver was dropped. A merely full (but alive) regular channel never reaches this reason – the offending event is dropped and the connection stays open instead.

Shutdown

The local caller side shut the connection down deliberately (every C2ControlHandle clone dropped) or the request id space was exhausted.
