Function Match

Match<This, Value>(matchingValue, opt?): DecoratorType<This, Value | Value[]>
@Match decorator

Define a decorator that gives the proper information to verify the content of a field. Binary files will often use magic number to validate the structure of the file.
Type Parameters
- This
- Value
Parameters
- matchingValue: Value | Value[]
- Optionalopt: Partial<ValidatorOptions>
Returns DecoratorType<This, Value | Value[]>
Example
The most simple use case is to compare to a number.
```
class Header {
   @Match(0xFE)
   @Relation(PrimitiveSymbol.char)
   magic: number,
}
```
The @Match decorator can also be used to match arrays.
```
class Header {
   @Match([0xBE, 0xEF])
   @Count(2)
   @Relation(PrimitiveSymbol.char)
   magic: number[],
}
```
Or to check the value is one of the value from an array passed as a parameter.
```
class Header {
   @Match([1, 8, 16])
   @Relation(PrimitiveSymbol.u8)
   magic: number,
}
```
Or an ASCII string.
```
class Header {
   @Match('.PNG')
   @Count(4)
   @Relation(PrimitiveSymbol.char)
   magic: string,
}
```
