# zakat


A comprehensive, type-safe, and Fiqh-compliant Zakat calculation library for Rust.

## Overview


This crate provides a complete solution for calculating Islamic Zakat obligations across all asset classes. It implements classical Fiqh rules with support for multiple schools of thought (Madhabs).

## Features


- Type-safe calculations using `rust_decimal` for financial precision
- Support for Gold, Silver, Business, Agriculture, Livestock, Income, and Modern Assets
- Madhab-aware calculation strategies (Hanafi, Shafi'i, Maliki, Hanbali)
- Internationalization with RTL language support
- Hawl (lunar year) tracking
- Live metal pricing integration
- Multiple platform targets: Native, WASM, Python, Dart, Kotlin

## Installation


```toml
[dependencies]
zakat = "1.0"
```

## Quick Start


```rust
use zakat::prelude::*;

fn main() -> Result<(), ZakatError> {
    // Configure with Hanafi rules
    let config = ZakatConfig::hanafi()
        .gold_price_per_gram(65.0)
        .silver_price_per_gram(0.80)
        .build()?;

    // Calculate gold zakat
    let gold = PreciousMetals::gold(100.0)
        .purity(24)
        .calculate_zakat(&config)?;

    println!("Zakat due: {}", gold.zakat_due);

    // Portfolio calculation
    let mut portfolio = ZakatPortfolio::new();
    portfolio.add(PreciousMetals::gold(100.0));
    portfolio.add(BusinessZakat::new().cash(50000.0).inventory(25000.0));

    let total = portfolio.calculate_total(&config)?;
    println!("Total Zakat: {}", total.total_zakat);

    Ok(())
}
```
