[−][src]Function tokio_sync::watch::channel
pub fn channel<T>(init: T) -> (Sender<T>, Receiver<T>)
Create a new watch channel, returning the "send" and "receive" handles.
All values sent by Sender
will become visible to the Receiver
handles.
Only the last value sent is made available to the Receiver
half. All
intermediate values are dropped.
Examples
extern crate tokio; use tokio::prelude::*; use tokio::sync::watch; let (mut tx, rx) = watch::channel("hello"); tokio::spawn(rx.for_each(|value| { println!("received = {:?}", value); Ok(()) }).map_err(|_| ())); tx.broadcast("world").unwrap();
