[][src]Struct actix_web::actix::TimerFunc

#[must_use = "future do nothing unless polled"]
pub struct TimerFunc<A> where
    A: Actor
{ /* fields omitted */ }

An ActorFuture that runs a function in the actor's context after a specified amount of time.

Unless you specifically need access to the future, use Context::run_later instead.

use std::time::Duration;
use actix::prelude::*;
use actix::utils::TimerFunc;

struct MyActor;

impl MyActor {
    fn stop(&mut self, context: &mut Context<Self>) {
        System::current().stop();
    }
}

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

   fn started(&mut self, context: &mut Context<Self>) {
       // spawn a delayed future into our context
       TimerFunc::new(Duration::from_millis(100), Self::stop)
           .spawn(context);
   }
}
