You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: duration_subsec.rs
    path of file: ./repos/rust-clippy/tests/ui
    
    the code of the file until where you have to start completion: #![allow(dead_code, clippy::needless_borrow)]
#![warn(clippy::duration_subsec)]

use std::time::Duration;

fn main() {
    let dur = Duration::new(5, 0);

    let bad_millis_1 = dur.subsec_micros() / 1_000;
    let bad_millis_2 = dur.subsec_nanos() / 1_000_000;
    let good_millis = 
    
fn main() {
    let dur = Duration::new(5, 0);

    let bad_millis_1 = dur.subsec_micros() / 1_000;
    let bad_millis_2 = dur.subsec_nanos() / 1_000_000;
    let good_millis = dur.subsec_millis();
    assert_eq!(bad_millis_1, good_millis);
    assert_eq!(bad_millis_2, good_millis);

    let bad_micros = dur.subsec_nanos() / 1_000;
    let good_micros = dur.subsec_micros();
    assert_eq!(bad_micros, good_micros);

    // Handle refs
    let _ = (&dur).subsec_nanos() / 1_000;

    // Handle constants
    const NANOS_IN_MICRO: u32 = 1_000;
    let _ = dur.subsec_nanos() / NANOS_IN_MICRO;

    // Other literals aren't linted
    let _ = dur.subsec_nanos() / 699;
}
