pub struct SystemRegistry { /* fields omitted */ }
Expand description
System wide actors registry
System registry serves same purpose as Registry, except it is shared across all arbiters.
Examples
use actix::prelude::*; #[derive(Message)] #[rtype(result = "()")] 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 = MyActor1::from_registry(); act.do_send(Ping); } } fn main() { // initialize system let code = System::new().block_on(async { // Start MyActor2 let addr = MyActor2.start(); }); }
Implementations
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
