Struct Receiver 

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

Receives the value of the Sender; a future.

Cancel safe: dropping the future before it completes loses nothing the channel still holds (a value sent later is dropped with the receiver).

Implementations

impl<T> Receiver<T>

pub fn close(&mut self)

Closes the receiving half: a later send fails and gets its value back. A value sent before the close stays receivable.

pub fn is_terminated(&self) -> bool

Whether the receiver completed or failed already.

pub fn is_empty(&self) -> bool

Whether no value is waiting for the receiver.

pub fn try_recv(&mut self) -> Result<T, TryRecvError>

Receives the value without waiting.

Errors

TryRecvError::Empty if no value was sent yet and the sender is still there; TryRecvError::Closed if the sender dropped without sending, the receiver was closed empty, or the value was received.

Trait Implementations

impl<T> Debug for Receiver<T>

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

Formats the value using the given formatter.

impl<T> Drop for Receiver<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> Future for Receiver<T>

type Output = Result<T, RecvError>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
