Struct Sender 

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

Sends one value to the Receiver.

Dropping it without sending ends the receiver’s wait with a RecvError.

Implementations

impl<T> Sender<T>

pub fn send(self, value: T) -> Result<(), T>

Sends the value and wakes the receiver. Never waits.

Errors

Gives the value back when the receiver is closed or gone.

pub async fn closed(&mut self)

Completes when the receiver has been closed or dropped. Cancel safe.

pub fn is_closed(&self) -> bool

Whether the receiver has been closed or dropped.

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

Polls whether the receiver has been closed or dropped; the waker of cx is woken when it is.

Trait Implementations

impl<T> 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.

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.
