Trait actix_web::actix::dev::Handler

pub trait Handler<M>: Actorwhere
    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.

Required 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

Implementations on Foreign Types

impl Handler<StopServer> for Server

type Result = Response<(), ()>

fn handle(
    &mut self,
    msg: StopServer,
    ctx: &mut Context<Server>
) -> <Server as Handler<StopServer>>::Result

impl Handler<PauseServer> for Server

type Result = ()

fn handle(&mut self, _: PauseServer, _: &mut Context<Server>)

impl Handler<ResumeServer> for Server

type Result = ()

fn handle(&mut self, _: ResumeServer, _: &mut Context<Server>)

impl Handler<Signal> for Server

Signals support Handle SIGINT, SIGTERM, SIGQUIT signals and stop actix system message to System actor.

type Result = ()

fn handle(&mut self, msg: Signal, ctx: &mut Context<Server>)
