Struct actix::Arbiter

pub struct Arbiter { /* fields omitted */ }

Event loop controller

Arbiter controls event loop in it's thread. Each arbiter runs in separate thread. Arbiter provides several api for event loop access. Each arbiter can belongs to specific System actor.

Methods

impl Arbiter

pub fn new<T: Into<String>>(name: T) -> Addr<Arbiter>

Spawn new thread and run event loop in spawned thread. Returns address of newly created arbiter.

pub fn name() -> String

Returns current arbiter's address

pub fn current() -> Addr<Arbiter>

Returns current arbiter's address

pub fn registry() -> Registry

This function returns arbiter's registry,

pub fn spawn<F>(future: F) where     F: Future<Item = (), Error = ()> + 'static,

Executes a future on the current thread.

pub fn spawn_fn<F, R>(f: F) where     F: FnOnce() -> R + 'static,     R: IntoFuture<Item = (), Error = ()> + 'static,

Executes a future on the current thread.

pub fn start<A, F>(f: F) -> Addr<A> where     A: Actor<Context = Context<A>>,     F: FnOnce(&mut A::Context) -> A + Send + 'static,

Start new arbiter and then start actor in created arbiter. Returns Addr<Syn, A> of created actor.

Trait Implementations

impl Actor for Arbiter

type Context = Context<Self>

Actor execution context type

fn started(&mut self, ctx: &mut Self::Context)

Method is called when actor get polled first time.

fn stopping(&mut self, ctx: &mut Self::Context) -> Running

Method is called after an actor is in Actor::Stopping state. There could be several reasons for stopping. Context::stop get called by the actor itself. All addresses to current actor get dropped and no more evented objects left in the context.

fn stopped(&mut self, ctx: &mut Self::Context)

Method is called after an actor is stopped, it can be used to perform any needed cleanup work or spawning more actors. This is final state, after this call actor get dropped.

fn start(self) -> Addr<Self> where     Self: Actor<Context = Context<Self>>,

Start new asynchronous actor, returns address of newly created actor.

fn start_default() -> Addr<Self> where     Self: Actor<Context = Context<Self>> + Default,

Start new asynchronous actor, returns address of newly created actor.

fn create<F>(f: F) -> Addr<Self> where     Self: Actor<Context = Context<Self>>,     F: FnOnce(&mut Context<Self>) -> Self + 'static,

Use create method, if you need Context object during actor initialization.

impl Handler<StopArbiter> for Arbiter

type Result = ()

The type of value that this handle will return

fn handle(&mut self, msg: StopArbiter, _: &mut Context<Self>)

Method is called for every message received by this Actor

impl<A> Handler<StartActor<A>> for Arbiter where     A: Actor<Context = Context<A>>,

type Result = Addr<A>

The type of value that this handle will return

fn handle(&mut self, msg: StartActor<A>, _: &mut Context<Self>) -> Addr<A>

Method is called for every message received by this Actor

impl<I: Send, E: Send> Handler<Execute<I, E>> for Arbiter

type Result = Result<I, E>

The type of value that this handle will return

fn handle(&mut self, msg: Execute<I, E>, _: &mut Context<Self>) -> Result<I, E>

Method is called for every message received by this Actor
