Enum Rdata 

#[non_exhaustive]
pub enum Rdata<'a> {
    A(A),
    AAAA(AAAA),
    Ptr(Ptr<'a>),
    Cname(Cname<'a>),
    Srv(Srv<'a>),
    Txt(Txt<'a>),

    Other(&'a [u8]),
}

Dispatched rdata view — interprets rdata per rtype.

Variants (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.

A(A)

Parsed A record (IPv4 address).

AAAA(AAAA)

Parsed AAAA record (IPv6 address).

Ptr(Ptr<'a>)

Parsed PTR record (domain name pointer).

Cname(Cname<'a>)

Parsed CNAME record (canonical name alias).

Srv(Srv<'a>)

Parsed SRV record (server location).

Txt(Txt<'a>)

Parsed TXT record (key=value text segments).

Nsec(Nsec<'a>)

Parsed NSEC record (negative-answer hint).

Other(&'a [u8])

Catch-all for record types this crate does not type-specifically parse (or for Unknown rtypes).
