my first fizzbuzz

fizzbuzz.rs

use std::io::Write;
use std::thread::{self, sleep, JoinHandle};
use std::time::Duration;

fn flush() {
    std::io::stdout().flush().unwrap();
}

fn main() {
    let mut threads: Vec<JoinHandle<()>> = Vec::new();

    threads.push(thread::spawn(|| {
        let mut i: u64 = 0;
        loop {
            i = i + 1;
            print!("\n{}", i);
            flush();
            sleep(Duration::from_secs(1));
        }
    }));

    threads.push(thread::spawn(|| {
        loop {
            print!("\rfizzbuzz");
            flush();
            sleep(Duration::from_secs(15));
        }
    }));

    threads.push(thread::spawn(|| {
        loop {
            print!("\rbuzz");
            flush();
            sleep(Duration::from_secs(5));
        }
    }));

    threads.push(thread::spawn(|| {
        loop {
            print!("\rfizz");
            flush();
            sleep(Duration::from_secs(3));
        }
    }));

    for thread in threads.into_iter() {
        let _ = thread.join();
    }
}
