Struct Sender

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

The transmission end of a channel.

This is created by the channel function.

Implementations

impl<T> Sender<T>

pub fn send(&self, item: T) -> Result<(), SendError<T>>

Sends the provided message along this channel.

pub fn close(&mut self)

Closes the sender half.

This prevents any further messages from being sent on the channel, by any sender, while still enabling the receiver to drain messages that are already buffered.

Trait Implementations

impl<T> Clone for Sender<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Sender<T>

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

Formats the value using the given formatter.

impl<T> Drop for Sender<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T> Sink<T> for Sender<T>

type Error = SendError<T>

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

fn poll_ready( self: Pin<&mut Self>, _: &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<(), SendError<T>>

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>, _: &mut Context<'_>, ) -> Poll<Result<(), SendError<T>>>

Flush any remaining output from this sink.

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

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