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(&self)

Closes the channel for every sender.

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

pub fn is_closed(&self) -> bool

Returns true if the channel is closed or the receiver has been dropped.

pub fn poll_closed(&self, cx: &mut Context<'_>) -> Poll<()>

Polls whether the channel is closed or the receiver has been dropped.

Only the task from the most recent call is woken, across this sender and all of its clones.

pub async fn closed(&self)

Waits until the channel is closed or the receiver has been dropped.

See poll_closed.

Trait Implementations

impl<T> Clone for Sender<T>

fn clone(&self) -> Sender<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Sender<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Drop for Sender<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<T> Unpin for Sender<T>
