How to Share Data Between Threads in Rust

Use std::sync::mpsc channels to send data between threads safely by moving ownership across thread boundaries.

use std::sync::mpsc;
use std::thread;

fn main() {
    let (tx, rx) = mpsc::channel();
    thread::spawn(move || {
        let val = String::from("hi");
        tx.send(val).unwrap();
    });
    let received = rx.recv().unwrap();
    println!("Got: {}", received);
}

Sharing data between threads in Rust lets one thread send a message to another without them sharing memory directly. Think of it like passing a note through a tube: the sender puts the note in, and the receiver takes it out, ensuring only one person holds the note at a time. You use this when you need to coordinate work between different parts of your program running at the same time.
