RFC 1035, DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION, November 1987

3.3. Standard RRs

The following RR definitions are expected to occur, at least
potentially, in all classes.  In particular, NS, SOA, CNAME, and PTR
will be used in all classes, and have the same format in all classes.
Because their RDATA format is known, all domain names in the RDATA
section of these RRs may be compressed.

<domain-name> is a domain name represented as a series of labels, and
terminated by a label with zero length.  <character-string> is a single
length octet followed by that number of characters.  <character-string>
is treated as binary information, and can be up to 256 characters in
length (including the length octet).

Methods

impl RData

fn parse(record_type: RecordType, tokens: &Vec<Token>, origin: Option<&Name>) -> ParseResult<Self>

fn read(decoder: &mut BinDecoder, record_type: RecordType, rdata_length: u16) -> DecodeResult<Self>

fn emit(&self, encoder: &mut BinEncoder) -> EncodeResult

RFC 4034, DNSSEC Resource Records, March 2005

6.2.  Canonical RR Form

   For the purposes of DNS security, the canonical form of an RR is the
   wire format of the RR where:

   ...

   3.  if the type of the RR is NS, MD, MF, CNAME, SOA, MB, MG, MR, PTR,
       HINFO, MINFO, MX, HINFO, RP, AFSDB, RT, SIG, PX, NXT, NAPTR, KX,
       SRV, DNAME, A6, RRSIG, or (rfc6840 removes NSEC), all uppercase
       US-ASCII letters in the DNS names contained within the RDATA are replaced
       by the corresponding lowercase US-ASCII letters;

Trait Implementations

impl Eq for RData

impl Clone for RData

fn clone(&self) -> RData

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for RData

fn eq(&self, __arg_0: &RData) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &RData) -> bool

This method tests for !=.

impl Debug for RData

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialOrd<RData> for RData

fn partial_cmp(&self, other: &RData) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Ord for RData

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.
