Struct actix::System[][src]

pub struct System { /* fields omitted */ }

System is an actor which manages runtime.

Before starting any actix's actors, System actor has to be created and started with System::run() call. This method creates new Arbiter in current thread and starts System actor.


extern crate actix;

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

struct Timer {
    dur: Duration,

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

    // stop system after `self.dur` seconds
    fn started(&mut self, ctx: &mut Context<Self>) {
        ctx.run_later(self.dur, |act, ctx| {
            // Stop current running system.

fn main() {
    // initialize system and run it.
    // This function blocks current thread
    let code = System::run(|| {
        // Start `Timer` actor
        Timer {
            dur: Duration::new(0, 1),
