Trait actix_web::actix::actix::Handler

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

Message handler

Handler implementation is a general way how to handle incoming messages, streams, futures.

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

Associated Types

type Result: MessageResponse<Self, M>

The type of value that this handle will return

Required Methods

fn handle(&mut self, msg: M, ctx: &mut Self::Context) -> Self::Result

Method is called for every message received by this Actor
