Struct futures::channel::oneshot::Receiver

#[must_use = "futures do nothing unless polled"]
pub struct Receiver<T> { /* fields omitted */ }

A future for a value that will be provided by another asynchronous task.

This is created by the channel function.

Methods

impl<T> Receiver<T>

pub fn close(&mut self)

Gracefully close this receiver, preventing any subsequent attempts to send to it.

Any send operation which happens after this method returns is guaranteed to fail. After calling this method, you can use Receiver::poll to determine whether a message had previously been sent.

impl<T> Future for Receiver<T>

type Item = T

A successful value

type Error = Canceled

An error

fn poll(&mut self, cx: &mut Context) -> Result<Async<T>, Canceled>

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