use quickcodes::{generate, BarcodeType, ExportFormat};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Generate QR Code as SVG
    let qr_svg = generate(BarcodeType::QRCode, "Hello!", ExportFormat::SVG)?;
    std::fs::write("qr_code.svg", qr_svg)?;
    
    // Generate EAN-13 as PNG  
    let ean_png = generate(BarcodeType::EAN13, "123456789012", ExportFormat::PNG)?;
    std::fs::write("barcode.png", ean_png)?;
    
    Ok(())
