Struct futures::unsync::mpsc::UnboundedSender

[+] Show declaration

pub struct UnboundedSender<T>(_);

[−] Expand description

The transmission end of an unbounded channel.

This is created by the unbounded function.

Methods

impl<T> UnboundedSender<T>

[−]

pub fn unbounded_send(&self, msg: T) -> Result<(), SendError<T>>

[−]

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.
