Struct actix_web::HttpContext

pub struct HttpContext<A, S = ()> where
    A: Actor<Context = HttpContext<A, S>>,  { /* fields omitted */ }

Http actor execution context

Methods

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

fn new(req: HttpRequest<S>, actor: A) -> HttpContext<A, S>

fn from_request(req: HttpRequest<S>) -> HttpContext<A, S>

fn actor(self, actor: A) -> HttpContext<A, S>

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

fn state(&self) -> &S

Shared application state

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

Incoming request

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

Write payload

fn write_eof(&mut self)

Indicate end of streaming payload. Also this method calls Self::close.

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

Returns drain future

fn connected(&self) -> bool

Check if connection still open

Trait Implementations

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

fn stop(&mut self)

Gracefully stop actor execution

fn terminate(&mut self)

Terminate actor execution

fn state(&self) -> ActorState

Actor execution state

fn alive(&self) -> bool

Check if execution context is alive

impl<A, S> AsyncContext<A> for HttpContext<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. idx is a value returned by spawn method.

fn address<Address>(&mut self) -> Address where
    A: ActorAddress<A, Address>, 

Get actor address

fn add_future<F>(&mut self, fut: F) where
    A: Handler<Result<<F as Future>::Item, <F as Future>::Error>>,
    F: Future + 'static,
    <F as Future>::Item: ResponseType, 

This method allow to handle Future in similar way as normal actor messages.

fn add_stream<S>(&mut self, fut: S) where
    A: Handler<Result<<S as Stream>::Item, <S as Stream>::Error>>,
    S: Stream + 'static,
    <S as Stream>::Item: ResponseType, 

This method is similar to add_future but works with streams.

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

This method is similar to add_stream but it skips errors.

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

Send message msg to self.

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

impl<A, S> ToEnvelope<A> for HttpContext<A, S> where
    A: Actor<Context = HttpContext<A, S>>, 

fn pack<M>(
    msg: M,
    tx: Option<Sender<Result<M::Item, M::Error>>>,
    channel_on_drop: bool
) -> Envelope<A> where
    A: Handler<M>,
    M: ResponseType + Send + 'static,
    M::Item: Send,
    M::Error: Send, 

Pack message into suitable envelope
