Enum SupervisionEvent 

pub enum SupervisionEvent {
    ActorStarted(ActorCell),
    ActorTerminated(ActorCell, Option<BoxedState>, Option<String>),
    ActorFailed(ActorCell, Box<dyn Error + Send + Sync>),
    ProcessGroupChanged(GroupChangeMessage),
}

A supervision event from the supervision tree

Variants

ActorStarted(ActorCell)

An actor was started

ActorTerminated(ActorCell, Option<BoxedState>, Option<String>)

An actor terminated. In the event it shutdown cleanly (i.e. didn’t panic or get signaled) we capture the last state of the actor which can be used to re-build an actor should the need arise. Includes an optional “exit reason” if it could be captured and was provided

ActorFailed(ActorCell, Box<dyn Error + Send + Sync>)

An actor failed (due to panic or error case)

ProcessGroupChanged(GroupChangeMessage)

A subscribed process group changed
