Money

This library provides an implementation of the Money Pattern in Rust, based on the Money Pattern defined by Martin Fowler, supporting various currencies, operator overloading for common arithmetic operations, and user-defined currencies.

Installation

Add the following to your Cargo.toml:

[dependencies]
money = { git = "https://github.com/mehmetcc/money" }

Example Usage

use money::{Money, Currency, Decimal};

fn main() {
    // Creating a new Currency for Bitcoin
    let bitcoin = Currency::new("BTC", "₿");
    let usd_currency = Currency::USD;
    let eur_currency = Currency::EUR;
    let gbp_currency = Currency::GBP;

    let money1 = Money::new(Decimal::new(100, 0), usd_currency);
    let money2 = Money::new(Decimal::new(50, 0), Currency::USD);
    let money3 = (money1.clone() + money2.clone()).unwrap();
    let money4 = (money3.clone() - money2.clone()).unwrap();
    let money5 = money2.clone() * Decimal::new(3, 0);

    println!("Money 1: {}", money1);
    println!("Money 2: {}", money2);
    println!("Money 3 (Money 1 + Money 2): {}", money3);
    println!("Money 4 (Money 3 - Money 2): {}", money4);
    println!("Money 5 (Money 2 * 3): {}", money5);

    // Example with different currencies
    let money6 = Money::new(Decimal::new(100, 0), eur_currency);
    println!("Money 6: {}", money6);

    // Example with custom Bitcoin currency
    let btc_money = Money::new(Decimal::new(1, 0), bitcoin);
    println!("Bitcoin Money: {}", btc_money);
}
