1. Open the Cargo.toml file that was  generated earlier for you.

2. Under [dependencies], add the following line:

rand = "0.4.2"

3. If you want, you can go to rand's crates.io page (https://crates.io/crates/rand) to check for the newest version and use that one instead.

4. In the folder bin, create a file called channels.rs.

5. Add the following code and run it with cargo run --bin channels:

1  extern crate rand;
2 
3  use rand::Rng;
4  use std::thread;
5  // mpsc stands for "Multi-producer, single-consumer"
6  use std::sync::mpsc::channel;
7 
8  fn main() {
9     // channel() creates a connected pair of a sender and a 
        receiver.
10    // They are usually called tx and rx, which stand for
11    // "transmission" and "reception"
12    let (tx, rx) = channel();
13    for i in 0..10 {
14        // Because an mpsc channel is "Multi-producer",
15        // the sender can be cloned infinitely
16        let tx = tx.clone();
17   ...
