Trait thespis::Actor

pub trait Actor: 'static {
    fn started(&mut self) -> Return<'_, ()> { ... }
    fn stopped(&mut self) -> Return<'_, ()> { ... }
}

An actor is an isolated computing unit that runs concurrently to other actors. You must implement this trait as well as Handler to accept messages.

The struct that implements this usually contains the (mutable) state that only this actor can directly access.

Mailbox implementations can decide to catch_unwind when your actor handles a message to keep the mailbox alive if the actor panics and make it possible to supervise actors. For this reason your actor should be std::panic::UnwindSafe. This might become a required trait bound in the future.

Provided methods

fn started(&mut self) -> Return<'_, ()>

Gets called just before the mailbox starts listening for incoming messages. You can use this to do setup for your actor.

fn stopped(&mut self) -> Return<'_, ()>

Gets called just after the mailbox stops listening for messages. You can use this to do cleanup.
