Struct Mailbox

Source 
pub struct Mailbox<A: Actor> {
    pub receiver: Receiver<A::Message>,
    pub stop: Receiver<A::Message>,
    pub this: WeakActorRef<A>,
}
Expand description

A mailbox for an actor, containing a receiver for messages, a receiver for stop messages, and a weak reference to the actor.

Importantly, we do not store a strong ActorRef in the mailbox, as the actor would otherwise keep itself alive even if all other references to it were dropped.
