let mut ct = cotar::Cotar::from_tar("example.tar.co").expect("Failed to ::from_tar()");

let file_name = "tiles/8/247/108.pbf.gz";

let file_info = ct.info(file_name).expect("Failed to .info()");

println!("ct.info('{}') {:?}", file_name, file_info);

// CotarIndexEntry { hash: 121498119488259422, offset: 7080448, size: 68 }

let file_data = ct.get(file_name).expect("Failed to .get()");

println!("ct.get('{}') {:?}", file_name, file_data);
