Variants (Non-exhaustive)

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

`DAU(SupportedAlgorithms)`

RFC 6975, DNSSEC Algorithm Understood

`DHU(SupportedAlgorithms)`

RFC 6975, DS Hash Understood

`N3U(SupportedAlgorithms)`

RFC 6975, NSEC3 Hash Understood

`Unknown(u16, Vec<u8, Global>)`

Unknown, used to deal with unknown or unsupported codes
