How to measure elapsed time in Rust

Answer 1

use std::thread;
use std::time::Instant;

fn main() {
    let start_time = Instant::now();

    // code to be measured 
    thread::sleep(std::time::Duration::from_secs(2));
    // code to be measured 

    let elapsed_time = start_time.elapsed().as_millis();

    println!("Elapsed time in milliseconds: {}", elapsed_time);
}


   
   
/*
run:
   
Elapsed time in milliseconds: 2000
   
*/
