[][src]Struct actix::System

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.

Examples

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.
            System::current().stop();
        });
    }
}

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),
        }.start();
    });

    std::process::exit(code);
}

Methods

impl System
[src]

Build a new system with a customized tokio runtime.

This allows to customize the runtime. See struct level docs on Builder for more information.

Create new system.

This method panics if it can not create tokio runtime

Get current running system.

Execute function with system reference.

Stop the system

System arbiter

Get current system registry.

This function will start tokio runtime and will finish once the System::stop() message get called. Function f get called within tokio runtime context.
