Trait thespis::Handler

pub trait Handler<M: Message> where
    Self: Actor, {
#[must_use = "Futures do nothing unless polled"]    fn handle(&mut self, msg: M) -> Return<'_, <M as Message>::Return>;

#[must_use = "Futures do nothing unless polled"]    fn handle_local(
        &mut self, 
        msg: M
    ) -> ReturnNoSend<'_, <M as Message>::Return> { ... }
}

Trait indicating that the implementor can receive messages of a certain type. An actor can implement Handler for as many types as desired.

Required methods

#[must_use = "Futures do nothing unless polled"]fn handle(&mut self, msg: M) -> Return<'_, <M as Message>::Return>

Define how your actor handles this message type. If your actor is !Send, you should implement handle_local and give handle an "unreachable!()" implementation. It shall never be called.

Provided methods

#[must_use = "Futures do nothing unless polled"]fn handle_local(&mut self, msg: M) -> ReturnNoSend<'_, <M as Message>::Return>

Define how your actor handles this message type.

You still have to implement handle because that is a required method, but if your actor is Send and you implement handle, you get handle_local automatically.
