Implementors are notified whenever actors are spawned or stopped. Methods are called on the actor’s task, so they should be cheap and non-blocking.

Required Methods

fn on_spawn( &self, path: &ActorPath, parent: Option<&ActorPath>, actor_type: &'static str, )

fn on_stop(&self, path: &ActorPath)

Provided Methods

fn on_mailbox_depth(&self, _path: &ActorPath, _depth: u64)

Called whenever the mailbox depth is sampled (optional).
