voicecode

为“生产可追溯性倡议”标签提供的voice code哈希器

参考： https://producetraceability.org/voice-pick-code-calculator/

此结构用于存储要哈希的所有输入部分以及结果输出。

请注意，示例实现返回区分大小写的输出，因此如果您的批号代码可能是混合大小写，请小心。

GTIN 123456789012和批号LOT123，包装日期为2003-01-02的示例

let voice_code = HashVoiceCode::new("123456789012", "LOT123", "01", "02", "03").unwrap();
println!("Voice Code: {}", voice_code.voice_code); // expects 8812
println!("Minor: {}", voice_code.voice_code_minor); // expects 88
println!("Major: {}", voice_code.voice_code_major); // expects 12

if let Some(date) = chrono::NaiveDate::from_ymd_opt(2003, 1, 2) {
    let voice_code = HashVoiceCode::new_naive("123456789012", "LOT123", date);
    println!("Voice Code: {}", voice_code.voice_code); // expects 8812
    println!("Minor: {}", voice_code.voice_code_minor); // expects 88
    println!("Major: {}", voice_code.voice_code_major); // expects 12
