Threads - Rust By Example
Description: A description

# Threads

Rust provides a mechanism for spawning native OS threads via the `spawn` function, the argument of this function is a moving closure.

    use std::thread;

    static NTHREADS: i32 = 10;

    // This is the `main` thread
    fn main() {
        // Make a vector to hold the children which are spawned.
        let mut children = vec![];

        for i in 0..NTHREADS {
            // Spin up another thread
            children.push(thread::spawn(move || {
                println!("this is thread number {}", i);
            }));
        }

        for child in children {
            // Wait for the thread to finish. Returns a result.
            let _ = child.join();
        }
    }

These threads will be scheduled by the OS.
