Return value

The ResponseCode, if this is an EDNS message then this will join the section from the OPT record to create the EDNS ResponseCode

pub fn queries(&self) -> &[Query]

Question        Carries the query name and other query parameters.

Authority       Carries RRs which describe other authoritative servers.
                May optionally carry the SOA RR for the authoritative
                data in the answer section.

pub fn take_name_servers(&mut self) -> Vec<Record>

Remove the name servers from the Message

                other sections.

pub fn take_additionals(&mut self) -> Vec<Record>

pub fn edns(&self) -> Option<&Edns>

RFC 6891, EDNS(0) Extensions, April 2013

6.1.1.  Basic Elements

 An OPT pseudo-RR (sometimes called a meta-RR) MAY be added to the
 additional data section of a request.

 The OPT RR has RR type 41.

 If an OPT record is present in a received request, compliant
 responders MUST include an OPT record in their respective responses.

 An OPT record does not carry any DNS data.  It is used only to
 contain control information pertaining to the question-and-answer
 sequence of a specific transaction.  OPT RRs MUST NOT be cached,
 forwarded, or stored in or loaded from master files.

 The OPT RR MAY be placed anywhere within the additional data section.
 When an OPT RR is included within any DNS message, it MUST be the
 only OPT RR in that message.  If a query message with more than one
 OPT RR is received, a FORMERR (RCODE=1) MUST be returned.  The
 placement flexibility for the OPT RR does not override the need for
 the TSIG or SIG(0) RRs to be the last in the additional section
 whenever they are present.

Return value

Returns the EDNS record if it was found in the additional section.

pub fn edns_mut(&mut self) -> &mut Edns

If edns is_none, this will create a new default Edns.

pub fn max_payload(&self) -> u16

Return value

the max payload value as it's defined in the EDNS section.

pub fn version(&self) -> u8

Return value

the version as defined in the EDNS record

pub fn sig0(&self) -> &[Record]

RFC 2535, Domain Name System Security Extensions, March 1999

A DNS request may be optionally signed by including one or more SIGs
 at the end of the query. Such SIGs are identified by having a "type
 covered" field of zero. They sign the preceding DNS request message
 including DNS header but not including the IP header or any request
 SIGs at the end and before the request RR counts have been adjusted
 for the inclusions of any request SIG(s).

Return value

The sig0, i.e. signed record, for verifying the sending and package integrity

pub fn to_vec(&self) -> Result<Vec<u8>, ProtoError>

Encodes the Message into a buffer

pub fn finalize<MF: MessageFinalizer>(     &mut self,     finalizer: &MF,     inception_time: u32 ) -> ProtoResult<()>

Finalize the message prior to sending.

Subsequent to calling this, the Message should not change.
