[−]Struct actix_web::actix::actix::dev::Registry
Actors registry
Actor can register itself as a service. Service can be defined as
ArbiterService
which is unique per arbiter or SystemService
which is
unique per system.
If arbiter service is used outside of running arbiter, it panics.
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 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 addres from the registry let act = Arbiter::registry().get::<MyActor1>(); act.do_send(Ping); } } fn main() { // initialize system let code = System::run(|| { // Start MyActor1 in new Arbiter Arbiter::start(|_| { MyActor2 }); }); }
Methods
impl Registry
impl Registry
pub fn get<A>(&self) -> Addr<A> where
A: Actor<Context = Context<A>> + ArbiterService,
pub fn get<A>(&self) -> Addr<A> where
A: Actor<Context = Context<A>> + ArbiterService,
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.
pub fn query<A>(&self) -> Option<Addr<A>> where
A: Actor<Context = Context<A>> + ArbiterService,
pub fn query<A>(&self) -> Option<Addr<A>> where
A: Actor<Context = Context<A>> + ArbiterService,
Check if actor is in registry, if so, return its address
pub fn set<A>(&self, addr: Addr<A>) where
A: Actor<Context = Context<A>> + ArbiterService,
pub fn set<A>(&self, addr: Addr<A>) where
A: Actor<Context = Context<A>> + ArbiterService,
Add new actor to the registry by address, panic if actor is already running
