A type-qualifying annotation that indicates the provided value must be a valid NBT type constant. Helps prevent the use
of simple integers over the constants available in Tag and verifies that the input is a valid type.
An annotation that can be applied to entire classes or packages to assume everything is not null by default. Or, y'know, you could just use Kotlin if you're into that.
@Resource (and variants)
A type-qualifying annotation applicable to strings that indicates the provided string must be part of a valid resource location. Handy in some cases. Offers namespace-specific and path-specific variants.
