Enum TerminationReason 

pub enum TerminationReason {
    Stopped,
    Panicked(String),
    RestartLimitExceeded,
}

Why an actor terminated — used by watches and restart policies.

Examples

impl Actor for Supervisor {
    type State = SupervisorState;

    fn on_actor_terminated(&mut self, state: &mut SupervisorState, event: &ActorTerminated) {
        match &event.reason {
            TerminationReason::Stopped => println!("{} stopped cleanly", event.label),
            TerminationReason::Panicked(msg) => println!("{} panicked: {msg}", event.label),
            TerminationReason::RestartLimitExceeded => println!("{} gave up", event.label),
        }
    }
}

Variants

Stopped

Clean shutdown (receptionist.stop() or channel close)

Panicked(String)

catch_unwind caught a panic

RestartLimitExceeded
