How to create a countdown seconds timer in Rust

Answer 1

use std::thread;
use std::time::Duration;

fn countdown(seconds: u32) {
    println!("Total time: {} seconds", seconds);

    let mut remaining = seconds;
    while remaining > 0 {
        thread::sleep(Duration::from_secs(1)); // Sleep for 1 second
        remaining -= 1;
        println!("Time remaining: {} seconds", remaining);
    }
}

fn main() {
    let sec = 5;

    countdown(sec);
}


   
/*
run:
  
Total time: 5 seconds
Time remaining: 4 seconds
Time remaining: 3 seconds
Time remaining: 2 seconds
Time remaining: 1 seconds
Time remaining: 0 seconds
  
*/
