Struct futures::sync::mpsc::UnboundedSender
[−]
[src]
pub struct UnboundedSender<T>(_);
The transmission end of a channel which is used to send values.
This is created by the unbounded
method.
Methods
impl<T> UnboundedSender<T>
[src]
fn unbounded_send(&self, msg: T) -> Result<(), SendError<T>>
[src]
Sends the provided 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.
