Rust program to demonstrate the and_hms_milli(), and_hms_micro(), and and_hms_nano() functions

Program/Source Code:

The source code to demonstrate and_hms_milli(), and_hms_micro(), and and_hms_nano() functions is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.

// Rust program to demonstrate and_hms_milli(), and_hms_micro(), 
// and and_hms_nano() functions

use chrono::prelude::*;

fn main() {
    let dt1 = Utc.ymd(2016, 10, 23).and_hms_milli(10, 12, 25,50);
    println!("Date time: {}", dt1);
    
    let dt2 = Utc.ymd(2016, 10, 23).and_hms_micro(10, 12, 25,50000);
    println!("Date time: {}", dt2);
    
    let dt3 = Utc.ymd(2016, 10, 23).and_hms_nano(10, 12, 25,50000000);
    println!("Date time: {}", dt3);
}

Output:

Explanation:

In the above program, we imported the "Chrono" library to our project for performing date and time operations. We imported the Chrono library using the below line:

use chrono::prelude::*;

In the main() function, we created date time objects using Utc.ymd(), and_hms_milli(), and_hms_micro(), and and_hms_nano() functions and printed the created objects.
