Trait actix::prelude::Handler

pub trait Handler<M, E = ()> where
    Self: Actor,
    M: ResponseType, {
    fn handle(&mut self, msg: M, ctx: &mut Self::Context) -> Response<Self, M>;

    fn error(&mut self, err: E, ctx: &mut Self::Context) { ... }
}

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. E is an optional error type, if message handler is used for handling Future or Stream results, then E type has to be set to correspondent Error type.

Required Methods

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

Method is called for every message received by this Actor

Provided Methods

fn error(&mut self, err: E, ctx: &mut Self::Context)

Method is called on error. By default it does nothing.
