Struct SendFuture 

Future
Source 
pub struct SendFuture<'a, T, Ch: Channel> { /* private fields */ }
Expand description

Future returned by Tx::send/MTx::send.

Resolves once the message has been written in the channel, or the channel is closed.

Message being sent can be retrieved with cancel, cancelling the future.

Implementations§

Source§

impl<'a, T, Ch: Channel> SendFuture<'a, T, Ch>

Source

pub fn cancel(self: Pin<&mut Self>) -> Option<T>

Cancels the send, returning the message if it has not yet been sent.

Trait Implementations§

Source§

impl<T, Ch: Channel> Future for SendFuture<'_, T, Ch>

Source§

type Output = Result<(), SendError<T>>

The type of value produced on completion.
Source§

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. Read more
