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

pub struct UnboundedSender<T>(_);

The transmission end of an unbounded mpsc channel.

This value is created by the unbounded function.

Methods

impl<T> UnboundedSender<T>[src]

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

Check if the channel is ready to receive a message.

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

Returns whether this channel is closed without needing a context.

pub fn close_channel(&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.

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

Send a message on the channel.

This method should only be called after poll_ready has been used to verify that the channel is ready to receive a message.

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

Sends a message along this channel.

This is an unbounded sender, so this function differs from Sink::send by ensuring the return type reflects that the channel is always ready to receive messages.
