pub fn edns(&self) -> Option<&Edns>
[src]
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
[src]
If edns is_none, this will create a new default Edns.
pub fn max_payload(&self) -> u16
[src]
Return value
the max payload value as it's defined in the EDNS section.
pub fn version(&self) -> u8
[src]
Return value
the version as defined in the EDNS record
pub fn sig0(&self) -> &[Record]
[src]
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>
[src]
Encodes the Message into a buffer
pub fn finalize<MF>(
&mut self,
finalizer: &MF,
inception_time: u32
) -> Result<(), ProtoError> where
MF: MessageFinalizer,
[src]
&mut self,
finalizer: &MF,
inception_time: u32
) -> Result<(), ProtoError> where
MF: MessageFinalizer,
Finalize the message prior to sending.
Subsequent to calling this, the Message should not change.
