rustHow to format datetime in Rust

Rust provides a powerful library for formatting and manipulating dates and times called chrono. It is a feature-rich library that supports a wide range of operations.

Example code

use chrono::{DateTime, Utc};

let now: DateTime<Utc> = Utc::now();
println!("{}", now.format("%Y-%m-%d %H:%M:%S"));

Output example

2020-09-17 11:45:00

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

Parts of the code:

• use chrono::{DateTime, Utc};: imports the DateTime and Utc types from the chrono library.
• let now: DateTime<Utc> = Utc::now();: creates a DateTime object representing the current date and time in UTC.
• println!("{}", now.format("%Y-%m-%d %H:%M:%S"));: prints the DateTime object in the specified format.
