pub struct Registry { /* fields omitted */ }
Expand description
Actors registry
An Actor can register itself as a service. A Service can be defined as an
ArbiterService
, which is unique per arbiter, or a SystemService
, which
is unique per system.
If an arbiter service is used outside of a running arbiter, it panics.
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 ArbiterService 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>) { // get MyActor1 address from the registry let act = MyActor1::from_registry(); act.do_send(Ping); } } fn main() { // initialize system let code = System::new().block_on(async { // Start MyActor2 in new Arbiter Arbiter::new().spawn_fn(|| { MyActor2.start(); }); }); }
Implementations
Query registry for specific actor. Returns address of the actor. If actor is not registered, starts new actor and return address of newly created actor.
Check if actor is in registry, if so, return its address
