Astrolabe

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, parsing and manipulating functions for date and time values.

Features

• Formatting and parsing with format strings based on Unicode Date Field Symbols
• RFC 3339 timestamp parsing and formatting
• Manipulation functions to add, subtract, set and clear date units
• Cron expression parser (With feature flag cron)
• Timezone offset
• Zero dependencies
• Serde serializing and deserializing (With feature flag serde)

Example

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

```rust use astrolabe::{DateTime, TimeUtilities, Precision};

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

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

// Create a new instance with a modified DateTime // The previous instance is not modified and is still in scope let modifieddt = datetime .addhours(11).unwrap() .addminutes(23).unwrap();

asserteq!("2022/05/02 11:23:00", modifieddt.format("yyyy/MM/dd HH:mm:ss")); asserteq!("2022-05-02T11:23:00Z", modifieddt.format_rfc3339(Precision::Seconds)); `` To see all implementations for theDateTime` struct, check out it's documentation.
