Execution context for WebSockets actors

Methods

impl<A, S: 'static> WebsocketContext<A, S> where     A: Actor<Context = Self>,

[−]

pub fn create<P>(req: HttpRequest<S>, actor: A, stream: WsStream<P>) -> Body where     A: StreamHandler<Message, ProtocolError>,     P: Stream<Item = Bytes, Error = PayloadError> + 'static,

[−]

Create a new Websocket context from a request and an actor

pub fn with_factory<F>(req: HttpRequest<S>, f: F) -> Body where     F: FnOnce(&mut Self) -> A + 'static,

[−]

Create a new Websocket context

impl<A, S> WebsocketContext<A, S> where     A: Actor<Context = Self>,

[−]

pub fn write_raw(&mut self, data: FramedMessage)

[−]

Write payload

This is a low-level function that accepts framed messages that should be created using Frame::message(). If you want to send text or binary data you should prefer the text() or binary() convenience functions that handle the framing for you.

pub fn state(&self) -> &S

[−]

Shared application state

pub fn request(&mut self) -> &mut HttpRequest<S>

[−]

Incoming request

pub fn drain(&mut self) -> Drain<A>

[−]

Returns drain future

pub fn text<T: Into<Binary>>(&mut self, text: T)

[−]

Send text frame

pub fn binary<B: Into<Binary>>(&mut self, data: B)

[−]

Send binary frame

pub fn ping(&mut self, message: &str)

[−]

Send ping frame

pub fn pong(&mut self, message: &str)

[−]

Send pong frame

pub fn close(&mut self, reason: Option<CloseReason>)

[−]

Send close frame

pub fn connected(&self) -> bool

[−]

Trait Implementations

impl<A, S> ActorContext for WebsocketContext<A, S> where     A: Actor<Context = Self>,

[+]

fn stop(&mut self)

[−]

Immediately stop processing incoming messages and switch to a stopping state

fn terminate(&mut self)

[−]

Terminate actor execution

fn state(&self) -> ActorState

[−]

Actor execution state

impl<A, S> AsyncContext<A> for WebsocketContext<A, S> where     A: Actor<Context = Self>,

[+]

fn spawn<F>(&mut self, fut: F) -> SpawnHandle where     F: ActorFuture<Item = (), Error = (), Actor = A> + 'static,

[−]

Spawn async future into context. Returns handle of the item, could be used for cancelling execution.

fn wait<F>(&mut self, fut: F) where     F: ActorFuture<Item = (), Error = (), Actor = A> + 'static,

[−]

Spawn future into the context. Stop processing any of incoming events until this future resolves.

fn cancel_future(&mut self, handle: SpawnHandle) -> bool

[−]

Cancel future. handle is a value returned by spawn method.

fn address(&self) -> Addr<A>

[−]

Return Address of the context

fn waiting(&self) -> bool

Check if context is paused (waiting for future completion or stopping)

fn add_stream<S>(&mut self, fut: S) -> SpawnHandle where     A: StreamHandler<<S as Stream>::Item, <S as Stream>::Error>,     S: Stream + 'static,

[−]

This method register stream to an actor context and allows to handle Stream in similar way as normal actor messages.

fn add_message_stream<S>(&mut self, fut: S) where     A: Handler<<S as Stream>::Item>,     S: Stream<Error = ()> + 'static,     <S as Stream>::Item: Message,

[−]

This method is similar to add_stream but it skips stream errors.

fn notify<M>(&mut self, msg: M) where     A: Handler<M>,     M: Message + 'static,

[−]

Send message msg to self.

fn notify_later<M>(&mut self, msg: M, after: Duration) -> SpawnHandle where     A: Handler<M>,     M: Message + 'static,

[−]

Send message msg to self after specified period of time. Returns spawn handle which could be used for cancellation. Notification get cancelled if context's stop method get called.

fn run_later<F>(&mut self, dur: Duration, f: F) -> SpawnHandle where     F: FnOnce(&mut A, &mut <A as Actor>::Context) + 'static,

[−]

Execute closure after specified period of time within same Actor and Context. Execution get cancelled if context's stop method get called.
