rustHow to format datetime string in Rust

Formatting a datetime string in Rust can be done using the chrono crate. This crate provides a DateTime type which can be used to parse and format datetime strings.

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

use chrono::{DateTime, Utc};

let datetime = Utc::now();
let formatted_datetime = datetime.format("%Y-%m-%d %H:%M:%S").to_string();

println!("Formatted datetime: {}", formatted_datetime);

Output

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

Explanation:

1. The chrono crate is imported to use the DateTime type.
2. The Utc::now() method is used to get the current datetime in UTC.
3. The format() method is used to format the datetime string according to the specified format string.
4. The to_string() method is used to convert the formatted datetime string to a String type.
5. The formatted datetime string is printed using the println! macro.
