ENUM_DESC & ENUM_TRS

提供一系列派生宏，用于向枚举添加描述性信息并简化枚举代码的翻译。
具体来说，以下宏用于增强枚举的额外功能："EnumDesc", "EnumDescI8", "EnumDescU8", "EnumDescI16", "EnumDescU16", "EnumDescI32", "EnumDescU32", "EnumDescI64", "EnumDescU64", "EnumDescISize", "EnumDescUSize"
另一方面，enum_trs属性宏使值的翻译成为可能，支持“等效翻译”和“标志翻译”。

示例 - EnumDesc

向枚举添加描述性信息

#[derive(EnumDesc, Debug)]
pub enum DeviceTypeEnum {
    #[info(desc = "mobile phone")]
    PHONE = 1,
    #[info(desc = "host computer")]
    PC = 2,
    #[info(desc = "tablet")]
    PAD = 3,
}

fn main() {
    println!("enum: {:#?}", DeviceTypeEnum::from_code(1));
    println!("code: {:#?}", DeviceTypeEnum::PC.to_code());
    println!("desc: {:#?}", DeviceTypeEnum::PC.get_desc());
    println!("desc: {:#?}", DeviceTypeEnum::got_desc(3));
}

运行上述代码，您将看到以下信息
     枚举：Some(PHONE)
     代码：2
     描述：主机计算机
     描述：平板电脑

示例 - enum_trs

翻译枚举代码

/// Ordinary Enumeration
#[derive(Debug, EnumDesc)]
pub enum GenderEnum {
    #[info(desc = "male")]
    MALE = 0,
    #[info(desc = "female")]
    FEMALE = 1,
}

/// Flagged Bit Enumeration, 
#[derive(Debug, EnumDescU8)]
pub enum AllowDeviceTypeEnum {
    #[info(desc = "mobile phone")]
    PHONE = 1,

    #[info(desc = "host computer")]
    PC = 2,

    #[info(desc = "tablet")]
    PAD = 4,
}

/// "=" is used for equivalent translation
/// "&"  is used for flag bit translation.
#[enum_trs(
gender = GenderEnum,
allow_device_type & AllowDeviceTypeEnum,
)]
#[derive(Debug)]
pub struct UserDto {
    pub name: String,
    pub gender: i16,
    pub allow_device_type: Option<u8>,
}

fn main() {
    let mut user_dto = UserDto {
        name: "hui".to_string(),
        gender: 1i16,
        allow_device_type: Some(7u8),
        gender_desc: "".to_string(),
        allow_device_type_desc: "".to_string(),
    };
    user_dto.translate_enums();
    println!("{:#?}", user_dto);
}

运行上述代码，您将看到以下信息
     UserDto {
         name: "hui",
         gender: 1,
         allow_device_type: Some(
             7,
         ),
         gender_desc: "female",
         allow_device_type_desc: "移动电话 | 主机计算机 | 平板电脑",
     }
