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

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
