Struct Sender 

pub struct Sender<T: Send + Sync> { /* private fields */ }

The sending half of a ring channel.

Implements Sink for sending items. Use SinkExt::send to send items asynchronously.

This type can be cloned to create multiple producers for the same channel. The channel remains open until all senders are dropped.

Implementations

impl<T: Send + Sync> Sender<T>

pub fn is_closed(&self) -> bool

Returns whether the receiver has been dropped.

If this returns true, subsequent sends will fail with ChannelClosed.

Trait Implementations

impl<T: Send + Sync> Clone for Sender<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Send + Sync> Drop for Sender<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: Send + Sync> Sink<T> for Sender<T>

type Error = ChannelClosed

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

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: T) -> 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(())).

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

Flush any remaining output from this sink.

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

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