Struct tokio::sync::mpsc::UnboundedSender

pub struct UnboundedSender<T> { /* private fields */ }

Send values to the associated UnboundedReceiver.

Instances are created by the unbounded_channel function.

Implementations

impl<T> UnboundedSender<T>

pub fn try_send(&mut self, message: T) -> Result<(), UnboundedTrySendError<T>>

Attempts to send a message on this UnboundedSender without blocking.

Trait Implementations

impl<T> Clone for UnboundedSender<T>

pub fn clone(&self) -> UnboundedSender<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for UnboundedSender<T>

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

Formats the value using the given formatter.

impl<T> Sink for UnboundedSender<T>

type SinkItem = T

The type of value that the sink accepts.

type SinkError = UnboundedSendError

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

pub fn start_send(
    &mut self,
    msg: T
) -> Result<AsyncSink<T>, <UnboundedSender<T> as Sink>::SinkError>

Begin the process of sending a value to the sink.

pub fn poll_complete(
    &mut self
) -> Result<Async<()>, <UnboundedSender<T> as Sink>::SinkError>

Flush all output from this sink, if necessary.

pub fn close(
    &mut self
) -> Result<Async<()>, <UnboundedSender<T> as Sink>::SinkError>

A method to indicate that no more values will ever be pushed into this sink.

fn wait(self) -> Wait<Self>

Creates a new object which will produce a synchronous sink.

fn with<U, F, Fut>(self, f: F) -> With<Self, U, F, Fut> where
    F: FnMut(U) -> Fut,
    Fut: IntoFuture<Item = Self::SinkItem>,
    <Fut as IntoFuture>::Error: From<Self::SinkError>, 

Composes a function in front of the sink.

fn with_flat_map<U, F, St>(self, f: F) -> WithFlatMap<Self, U, F, St> where
    F: FnMut(U) -> St,
    St: Stream<Item = Self::SinkItem, Error = Self::SinkError>, 

Composes a function in front of the sink.

fn sink_map_err<F, E>(self, f: F) -> SinkMapErr<Self, F> where
    F: FnOnce(Self::SinkError) -> E, 

Transforms the error returned by the sink.

fn sink_from_err<E>(self) -> SinkFromErr<Self, E> where
    E: From<Self::SinkError>, 

Map this sink’s error to any error implementing From for this sink’s Error, returning a new sink.

fn buffer(self, amt: usize) -> Buffer<Self>

Adds a fixed-size buffer to the current sink.

fn fanout<S>(self, other: S) -> Fanout<Self, S> where
    S: Sink<SinkItem = Self::SinkItem, SinkError = Self::SinkError>,
    Self::SinkItem: Clone, 

Fanout items to multiple sinks.

fn flush(self) -> Flush<Self>

A future that completes when the sink has finished processing all pending requests.

fn send(self, item: Self::SinkItem) -> Send<Self>

A future that completes after the given item has been fully processed into the sink, including flushing.

fn send_all<S>(self, stream: S) -> SendAll<Self, S> where
    S: Stream<Item = Self::SinkItem>,
    Self::SinkError: From<<S as Stream>::Error>, 

A future that completes after the given stream has been fully processed into the sink, including flushing.
