Struct futures_channel::mpsc::Sender[][src]

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

The transmission end of a bounded mpsc channel.

This value is created by the channel function.

Methods

impl<T> Sender<T>
[src]

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

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.

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

Return value

This method returns:

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

Returns whether this channel is closed without needing a context.

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