Struct trust_dns_proto::xfer::dns_request::DnsRequest [−][src]
pub struct DnsRequest { /* fields omitted */ }
Expand description
A DNS request object
This wraps a DNS Message for requests. It also has request options associated for controlling certain features of the DNS protocol handlers.
Implementations
Returns a new DnsRequest object
Get the set of request options associated with this request
Unwraps the raw message
Methods from Deref<Target = Message>
Truncates a Message, this blindly removes all response fields and sets truncated to true
see Header::set_message_type
see Header::set_op_code
see Header::set_authoritative
see Header::set_truncated
see Header::set_recursion_desired
see Header::set_recursion_available
see Header::set_authentic_data
see Header::set_checking_disabled
see Header::set_response_code
Add a query to the Message, either the query response from the server, or the request Query.
pub fn add_queries<Q, I>(&mut self, queries: Q) -> &mut Self where
Q: IntoIterator<Item = Query, IntoIter = I>,
I: Iterator<Item = Query>,
pub fn add_queries<Q, I>(&mut self, queries: Q) -> &mut Self where
Q: IntoIterator<Item = Query, IntoIter = I>,
I: Iterator<Item = Query>,
Adds an iterator over a set of Queries to be added to the message
Add an answer to the Message
pub fn add_answers<R, I>(&mut self, records: R) -> &mut Self where
R: IntoIterator<Item = Record, IntoIter = I>,
I: Iterator<Item = Record>,
pub fn add_answers<R, I>(&mut self, records: R) -> &mut Self where
R: IntoIterator<Item = Record, IntoIter = I>,
I: Iterator<Item = Record>,
Add all the records from the iterator to the answers section of the Message
Sets the answers to the specified set of Records.
Panics
Will panic if answer records are already associated to the message.
Add a name server record to the Message
pub fn add_name_servers<R, I>(&mut self, records: R) -> &mut Self where
R: IntoIterator<Item = Record, IntoIter = I>,
I: Iterator<Item = Record>,
pub fn add_name_servers<R, I>(&mut self, records: R) -> &mut Self where
R: IntoIterator<Item = Record, IntoIter = I>,
I: Iterator<Item = Record>,
Add all the records in the Iterator to the name server section of the message
Sets the name_servers to the specified set of Records.
Panics
Will panic if name_servers records are already associated to the message.
Add an additional Record to the message
Sets the additional to the specified set of Records.
Panics
Will panic if additional records are already associated to the message.
This is supported on crate feature dnssec
only.
dnssec
only.Add a SIG0 record, i.e. sign this message
This must be used only after all records have been associated. Generally this will be handled by the client and not need to be used directly
This is supported on crate feature dnssec

dnssec
only.Add a TSIG record, i.e. authenticate this message
This must be used only after all records have been associated. Generally this will be handled by the client and not need to be used directly

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
Provides mutable access to queries
Removes all the answers from the Message
Provides mutable access to answers
Removes all the answers from the Message
Authority Carries RRs which describe other authoritative servers.
May optionally carry the SOA RR for the authoritative
data in the answer section.
Provides mutable access to name_servers
Remove the name servers from the Message
Additional Carries RRs which may be helpful in using the RRs in the
other sections.
Provides mutable access to additionals
Remove the additional Records from the Message
All sections chained
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 Zone 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.
Return value
the max payload value as it’s defined in the EDNS section.
Return value
the version as defined in the EDNS 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 and tsig, i.e. signed record, for verifying the sending and package integrity

Remove signatures from the Message
pub fn finalize<MF: MessageFinalizer>(
&mut self,
finalizer: &MF,
inception_time: u32
) -> ProtoResult<Option<MessageVerifier>>
pub fn finalize<MF: MessageFinalizer>(
&mut self,
finalizer: &MF,
inception_time: u32
) -> ProtoResult<Option<MessageVerifier>>
Finalize the message prior to sending.
Subsequent to calling this, the Message should not change.
