Struct actix::MessageResult

source ·
pub struct MessageResult<M: Message>(pub M::Result);
Expand description

A helper type that implements the MessageResponse trait.

§Examples

use actix::prelude::*;

#[derive(Message)]
#[rtype(Response)]
struct Msg;

struct Response;

struct MyActor;

impl Actor for MyActor {
    type Context = Context<Self>;
}

impl Handler<Msg> for MyActor {
    type Result = MessageResult<Msg>;

    fn handle(&mut self, _: Msg, _: &mut Context<Self>) -> Self::Result {
        MessageResult(Response {})
    }
}
