zakat = "0.1.3"

rust_decimal = "1.39"

rust_decimal_macros = "1.39"

Usage

Business Zakat

use zakat::{ZakatConfig, CalculateZakat};
use zakat::maal::business::{BusinessAssets, BusinessZakatCalculator};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = ZakatConfig::new(65, 1); // gold $65/g, silver $1/g

    let assets = BusinessAssets::new(
        50000, // cash
        20000, // inventory
        5000,  // receivables
        1000   // debt
    )?;

    let calc = BusinessZakatCalculator::new(assets, &config)?
                     .with_label("Main Store")
                     .with_hawl(true)
                     .with_debt(1000); // Additional debts

    let result = calc.calculate_zakat()?;

    if result.is_payable {
        println!("Zakat for {}: ${}", result.label.unwrap_or_default(), result.zakat_due);
    }
    Ok(())
}

Portfolio

use zakat::{ZakatConfig, ZakatPortfolio, WealthType};
use zakat::maal::precious_metals::PreciousMetal;
use zakat::maal::investments::{InvestmentAssets, InvestmentType};
use zakat::maal::income::{IncomeZakatCalculator, IncomeCalculationMethod};
use rust_decimal_macros::dec;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = ZakatConfig::new(65, 1);

    let portfolio = ZakatPortfolio::new()
        .add_calculator(IncomeZakatCalculator::new(
            5000, 0, IncomeCalculationMethod::Gross, &config
        )?.with_label("Monthly Salary"))
        .add_calculator(PreciousMetal::new(
            100, WealthType::Gold, &config
        )?.with_label("Wife's Gold"))
        .add_calculator(InvestmentAssets::new(
            20000, InvestmentType::Crypto, &config
        )?.with_debt(dec!(2000.0)).with_label("Binance Portfolio"));

    let result = portfolio.calculate_total(&config)?;
    println!("Total Zakat Due: ${}", result.total_zakat_due);
    
    // Iterate details to see labels
    for detail in result.details {
        if let Some(label) = detail.label {
            println!(" - {}: ${}", label, detail.zakat_due);
        }
    }
    Ok(())
}

Custom Nisab

use zakat::ZakatConfig;

let config = ZakatConfig::new(65, 1)
    .with_gold_nisab(87)
    .with_agriculture_nisab(700);
