rustHow to convert datetime to timestamp in Rust

Converting a datetime to a timestamp in Rust is a simple process. The chrono crate provides a Timestamp type which can be used to convert a DateTime to a timestamp.

Example code

use chrono::{DateTime, Timestamp};

let dt = DateTime::parse_from_rfc3339("2020-01-01T12:00:00+00:00").unwrap();
let ts = Timestamp::from_datetime(&dt);

Output example

1577836800

The code above:

• use chrono::{DateTime, Timestamp};: imports the DateTime and Timestamp types from the chrono crate.
• let dt = DateTime::parse_from_rfc3339("2020-01-01T12:00:00+00:00").unwrap();: parses a DateTime from an RFC 3339 string.
• let ts = Timestamp::from_datetime(&dt);: converts the DateTime to a timestamp.
