Trait actix::Handler

pub trait Handler<M> where
    Self: Actor,
    M: Message, {
    type Result: MessageResponse<Self, M>;
    fn handle(&mut self, msg: M, ctx: &mut Self::Context) -> Self::Result;
}

Describes how to handle messages of a specific type.

Implementing Handler is a general way to handle incoming messages, streams, and futures.

The type M is a message which can be handled by the actor.
