/*！
The library provides `Encode` to encode values, `Decode` to decode values, and `TagValue` to manipulate tag data values. The library already implements `Encode` and `Decode` for some rust types: `bool`,`i8`,`u8`,`i16`,`u16`,`i32`,`u32`,`i64`,`u64`,`f32`,`f64`,`i128`,`u128`,`()`,`Option`,`Tuple`,`Vec`,`[T;N]`,`SmallVec`. For structure type, you need to implement `Encode` and `Decode` by yourself.
