[][src]Struct futures::channel::mpsc::Sender

pub struct Sender<T>(_);

The transmission end of a bounded mpsc channel.

This value is created by the channel function.

Methods

impl<T> Sender<T>[src]

pub fn try_send(&mut self, msg: T) -> Result<(), TrySendError<T>>[src]

Attempts to send a message on this Sender, returning the message if there was an error.

pub fn start_send(&mut self, msg: T) -> Result<(), SendError>[src]

Send a message on the channel.

This function should only be called after poll_ready has reported that the channel is ready to receive a message.

pub fn poll_ready(&mut self, cx: &mut Context) -> Poll<Result<(), SendError>>[src]

Polls the channel to determine if there is guaranteed capacity to send at least one item without waiting.

Return value

This method returns:

  • Poll::Ready(Ok(_)) if there is sufficient capacity;
  • Poll::Pending if the channel may not have capacity, in which case the current task is queued to be notified once capacity is available;
  • Poll::Ready(Err(SendError)) if the receiver has been dropped.

pub fn is_closed(&self) -> bool[src]

Returns whether this channel is closed without needing a context.

pub fn close_channel(&mut self)[src]

Closes this channel from the sender side, preventing any new messages.

pub fn disconnect(&mut self)[src]

Disconnects this sender from the channel, closing it if there are no more senders left.
