}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

Methods
impl Query
fn new() -> Self
return a default query with an empty name and A, IN for the query_type and query_class
fn name(&mut self, name: Name) -> &mut Self
replaces name with the new name
fn query_type(&mut self, query_type: RecordType) -> &mut Self
fn query_class(&mut self, query_class: DNSClass) -> &mut Self
fn get_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.
fn get_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.
fn get_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.
