Crate zbar_pack 

Safe Rust bindings for ZBar barcode scanner library

This crate provides a safe Rust wrapper around the ZBar C library, with static linking of vendored ZBar source code by default.

Features

• vendored (default): Compile and statically link bundled ZBar source
• system: Use system-installed ZBar library
• dynamic: Dynamically link system ZBar library
• all-codecs (default): Enable all codecs
• minimal: Minimal build, manually enable required codecs

License Compliance

ZBar is licensed under LGPLv2.1+. When statically linking, this project must:

• Provide complete ZBar source code and build instructions (see zbar-src/)
• Allow end users to replace/relink the library
• See COMPLIANCE.md for details

Example

use zbar_pack::{ImageScanner, Image, SymbolType};

let mut scanner = ImageScanner::new()?;
scanner.set_config(SymbolType::QRCODE, 0, 1)?;

// Example: 100x100 grayscale image
let data: Vec<u8> = vec![0; 100 * 100];
let image = Image::from_gray(&data, 100, 100)?;
let symbols = scanner.scan_image(&image)?;

for symbol in symbols {
    println!("Type: {:?}, Data: {}", symbol.symbol_type(), symbol.data());
}
