[]Struct actix_web::actix::actix::dev::SystemRegistry

pub struct SystemRegistry { /* fields omitted */ }

System wide actors registry

System registry serves same purpose as Registry, except it is shared across all arbiters.

Example

use actix::prelude::*;

#[derive(Message)]
struct Ping;

#[derive(Default)]
struct MyActor1;

impl Actor for MyActor1 {
    type Context = Context<Self>;
}
impl actix::Supervised for MyActor1 {}

impl SystemService for MyActor1 {
    fn service_started(&mut self, ctx: &mut Context<Self>) {
        println!("Service started");
    }
}

impl Handler<Ping> for MyActor1 {
    type Result = ();

    fn handle(&mut self, _: Ping, ctx: &mut Context<Self>) {
        println!("ping");
    }
}

struct MyActor2;

impl Actor for MyActor2 {
    type Context = Context<Self>;

    fn started(&mut self, _: &mut Context<Self>) {
        let act = System::current().registry().get::<MyActor1>();
        act.do_send(Ping);
    }
}

fn main() {
    // initialize system
    let code = System::run(|| {
        // Start MyActor1
        let addr = MyActor1.start();

        // Start MyActor2
        let addr = MyActor2.start();
    });
}

Methods

impl SystemRegistry

Return address of the service. If service actor is not running it get started in the system.

Check if actor is in registry, if so, return its address

Add new actor to the registry by address, panic if actor is already running
