rustHow to format date string in Rust

Formatting date strings in Rust can be done using the chrono crate. This crate provides a wide range of formatting options for dates and times.

Below is an example of how to format a date string in Rust:

use chrono::{DateTime, Utc};

let now: DateTime<Utc> = Utc::now();
let formatted_date = now.format("%Y-%m-%d %H:%M:%S").to_string();

println!("Formatted date: {}", formatted_date);

Output

Formatted date: 2020-09-17 13:45:12

Explanation:

1. The chrono crate is imported with use chrono::{DateTime, Utc};
2. The current date and time is obtained with let now: DateTime<Utc> = Utc::now();
3. The date is formatted with let formatted_date = now.format("%Y-%m-%d %H:%M:%S").to_string();
4. The formatted date is printed with println!("Formatted date: {}", formatted_date);
