Methods
impl<A> Context<A> where
A: Actor<Context = Self>,
[src]
A: Actor<Context = Self>,
pub fn handle(&self) -> SpawnHandle
[src]

F: ActorFuture<Item = (), Error = (), Actor = A> + 'static,
[src]
F: ActorFuture<Item = (), Error = (), Actor = A> + 'static,

[src]
F: ActorFuture<Item = (), Error = (), Actor = A> + 'static,
Spawn future into the context. Stop processing any of incoming events until this future resolves. Read more
fn waiting(&self) -> bool
[src]
Check if context is paused (waiting for future completion or stopping)
fn cancel_future(&mut self, handle: SpawnHandle) -> bool
[src]
Cancel future. idx is a value returned by spawn
method.

S: Stream + 'static,
A: StreamHandler<S::Item, S::Error>,
[src]
S: Stream + 'static,
A: StreamHandler<S::Item, S::Error>,
This method allow to handle Stream
in similar way as normal actor messages. Read more
