dayjs

A Rust library providing a JavaScript Day.js-like API for date and time manipulation, built on top of chrono.

Features

• Simple API: JavaScript Day.js-inspired interface for Rust developers
• Timezone Support: Handle different timezone formats (offset, city names, numeric)
• Multiple Parsing Formats: Support for RFC3339, RFC2822, UTC suffix, and more
• Chainable Operations: Add/subtract time units with method chaining
• Type Safety: Leverages Rust's type system for safe time operations
• Zero-cost Abstractions: Built on chrono for high performance

Installation

Add this to your Cargo.toml:

[dependencies]
dayjs = "^0.1"

Usage

fn main() {
    // current date and time
    let now = dayjs::now();

    // Create and manipulate dates
    let mut date = dayjs::from_str("2025-01-25T10:30:45Z").unwrap();

    // Add 30 days
    date.add_days(30);

    // Format output
    println!("ISO: {}", date.to_iso());
    println!("Custom: {}", date.format("%Y年%m月%d日 %H:%M:%S"));
}
