Documentation

Overview

Astrolabe is a date and time library for Rust which aims to be feature rich, lightweight (zero dependencies) and easy-to-use. It implements formatting and manipulating functions for date and time values.

Features

  • Formatting with format strings based on Unicode Date Field Symbols
  • RFC3339 timestamp parsing and formatting
  • Manipulation functions to easily add, remove or set date units
  • Timezone offset
  • Zero dependencies

Example

A basic example which demonstrates creating, formatting and manipulating a DateTime instance.

use astrolabe::{DateTime, Precision, DateTimeUnit};

// Create a DateTime instance from year, month, and days (day of month)
let date_time = DateTime::from_ymd(2022, 5, 2).unwrap();

// Use the format function to freely format your DateTime instance
assert_eq!("2022/05/02", date_time.format("yyyy/MM/dd"));

// Create a new instance with a modified DateTime
// The previous instance is not modified and is still in scope
let modified_dt = date_time
    .apply(11, DateTimeUnit::Hour).unwrap()
    .apply(23, DateTimeUnit::Min).unwrap();

assert_eq!("2022/05/02 11:23:00", modified_dt.format("yyyy/MM/dd HH:mm:ss"));
assert_eq!("2022-05-02T11:23:00Z", modified_dt.format_rfc3339(Precision::Seconds));
