Struct `Iter`

pub struct Iter<'a, T: 'a> { pub(in ::sync::mpmc) rx: &'a Receiver<T> }

An iterator over messages on a Receiver, created by iter.

This iterator will block whenever next is called, waiting for a new message, and None will be returned when the corresponding channel has hung up.

Examples

#![feature(mpmc_channel)]

use std::sync::mpmc::channel;
use std::thread;

let (send, recv) = channel();

thread::spawn(move || {
    send.send(1u8).unwrap();
    send.send(2u8).unwrap();
    send.send(3u8).unwrap();
});

for x in recv.iter() {
    println!("Got: {x}");
}

Fields

rx: &'a Receiver<T>
