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.

`Zero`

RFC 6891, Reserved

`LLQ`

RFC 8764l, Apple’s Long-Lived Queries, Optional

`UL`

`NSID`

`DAU`

RFC 6975, DNSSEC Algorithm Understood

`DHU`

RFC 6975, DS Hash Understood

`N3U`

RFC 6975, NSEC3 Hash Understood

`Subnet`

RFC 7871, Client Subnet, Optional

`Expire`

RFC 7314, EDNS EXPIRE, Optional

`Cookie`

RFC 7873, DNS Cookies

`Keepalive`

RFC 7828, edns-tcp-keepalive

`Padding`

RFC 7830, The EDNS(0) Padding

`Chain`

RFC 7901, CHAIN Query Requests in DNS, Optional

`Unknown(u16)`

Unknown, used to deal with unknown or unsupported codes
