rustHow to format date in Rust

Rust provides a number of ways to format dates.

The most common way is to use the chrono crate. This crate provides a number of functions to format dates and times.

Example code

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 example

Formatted date: 2020-09-17 15:45:12

The code above uses the chrono crate to get the current date and time in UTC and then formats it using the format function. The format string %Y-%m-%d %H:%M:%S specifies the format of the output.

Code explanation

• use chrono::{DateTime, Utc};: imports the DateTime and Utc types from the chrono crate.
• let now: DateTime<Utc> = Utc::now();: gets the current date and time in UTC.
• let formatted_date = now.format("%Y-%m-%d %H:%M:%S").to_string();: formats the date and time using the format function and converts it to a string.
• println!("Formatted date: {}", formatted_date);: prints the formatted date.
