Struct gloo_worker::reactor::ReactorBridge

pub struct ReactorBridge<R>
where
    R: Reactor + 'static,
{ /* private fields */ }

A connection manager for components interaction with oneshot workers.

As this type implements [Stream] + [Sink], it can be splitted with [StreamExt::split].

Implementations

impl<R> ReactorBridge<R>

where R: Reactor + 'static,

pub fn fork(&self) -> Self

Forks the bridge.

This method creates a new bridge connected to a new reactor on the same worker instance.

pub fn send_input(&self, msg: <R::Scope as ReactorScoped>::Input)

Sends an input to the current reactor.

Trait Implementations

impl<R> Debug for ReactorBridge<R>

where R: Reactor,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<R> FusedStream for ReactorBridge<R>

where R: Reactor + 'static,

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<R> Sink<<<R as Reactor>::Scope as ReactorScoped>::Input> for ReactorBridge<R>

where R: Reactor + 'static,

type Error = ReactorBridgeSinkError

The type of value produced by the sink when an error occurs.

fn poll_close( self: Pin<&mut Self>, _cx: &mut Context<'_> ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.

fn poll_flush( self: Pin<&mut Self>, _cx: &mut Context<'_> ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_ready( self: Pin<&mut Self>, _cx: &mut Context<'_> ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send( self: Pin<&mut Self>, item: <R::Scope as ReactorScoped>::Input ) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

impl<R> Stream for ReactorBridge<R>

where R: Reactor + 'static,

type Item = <<R as Reactor>::Scope as ReactorScoped>::Output

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
