null-kane

This is a Rust crate designed for currency manipulation. It provides an interface via a trait for implementing localization methods. The trait enables retrieval of the currency separator, thousand separator, and currency symbol.

Features

Localization Methods

• get_separator: Retrieves the separator used for the currency.
• get_thousand_separator: Retrieves the thousand separator used for the currency.
• get_currency_symbol: Retrieves the currency symbol.

Arithmetic Operations

The crate implements arithmetic operations for the following types:

• Addition, multiplication, and division among currencies.
• Addition, multiplication, and division between currencies and usize.
• Addition, multiplication, and division between currencies and f32.
• Addition, multiplication, and division between currencies and f64.

Constructors

From implementations for creating instances from f32 and f64.

Example

use null_kane::{Currency, CurrencyLocalization};

#[derive(Clone, Default, PartialEq, Eq)]
enum MyLocalization {
    #[default]
    Euro
}

impl CurrencyLocalization for MyLocalization {
    fn get_separator(&self) -> char {
        // Implementation of the separator for Euro
        ','
    }

    fn get_thousand_separator(&self) -> char {
        // Implementation of the thousand separator for Euro
        '.'
    }

    fn get_currency_symbol(&self) -> &'static str {
        // Implementation of the currency symbol for Euro
        "€"
    }
}

fn main() {
    let euro_currency = MyLocalization::default;
    let amount_one = Currency::from(50.25_f32).with_locale(euro_currency.clone());
    let amount_two = Currency::from(30.75_f64).with_locale(euro_currency);

    let sum = amount_one + amount_two;
    let product = amount_one * 2.0;
    let division = amount_two / 3.0;

    println!("Sum: {}", sum);
    println!("Product: {}", product);
    println!("Division: {}", division);
}
