pub struct Query { /* private fields */ }

Expand description

Query struct for looking up resource records, basically a resource record without RDATA.

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

4.1.2. Question section format

The question section is used to carry the "question" in most queries,
i.e., the parameters that define what is being asked.  The section
contains QDCOUNT (usually 1) entries, each of the following format:

                                    1  1  1  1  1  1
      0  1  2  3  4  5  6  7  8  9  0  1  2  3  4  5
    +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
    |                                               |
    /                     QNAME / ZNAME             /
    /                                               /
    +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
    |                     QTYPE / ZTYPE             |
    +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
    |                     QCLASS / ZCLASS           |
    +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+

Implementations

source

impl Query

source

pub fn new() -> Self

Return a default query with an empty name and A, IN for the query_type and query_class

source

pub fn query(name: Name, query_type: RecordType) -> Self

Create a new query from name and type, class defaults to IN

source

pub fn set_name(&mut self, name: Name) -> &mut Self

replaces name with the new name

source

pub fn set_query_type(&mut self, query_type: RecordType) -> &mut Self

Specify the RecordType being queried

source

pub fn set_query_class(&mut self, query_class: DNSClass) -> &mut Self

Specify÷ the DNS class of the Query, almost always IN

source

pub fn set_mdns_unicast_response(&mut self, flag: bool) -> &mut Self

This is supported on crate feature mdns only.

Changes mDNS unicast-response bit See RFC 6762

source

pub fn name(&self) -> &Name

QNAME           a domain name represented as a sequence of labels, where
                each label consists of a length octet followed by that
                number of octets.  The domain name terminates with the
                zero length octet for the null label of the root.  Note
                that this field may be an odd number of octets; no
                padding is used.

source

pub fn query_type(&self) -> RecordType

QTYPE           a two octet code which specifies the type of the query.
                The values for this field include all codes valid for a
                TYPE field, together with some more general codes which
                can match more than one type of RR.

source

pub fn query_class(&self) -> DNSClass

QCLASS          a two octet code that specifies the class of the query.
                For example, the QCLASS field is IN for the Internet.

source

pub fn mdns_unicast_response(&self) -> bool

This is supported on crate feature mdns only.

Returns if the mDNS unicast-response bit is set or not See RFC 6762

source

pub fn into_parts(self) -> QueryParts
