\\R* R, 4S jrS rS rSrg)Answer a DNS stub resolver answer.
Instances of this class bundle up the result of a successful DNS
resolution.
For convenience, the answer object implements much of the sequence
protocol, forwarding to its ``rrset`` attribute. E.g.
``for a in answer`` is equivalent to ``for a in answer.rrset``.
``answer[i]`` is equivalent to ``answer.rrset[i]``, and
``answer[i:j]`` is equivalent to ``answer.rrset[i:j]``.
Note that CNAMEs or DNAMEs in the response may mean that answer
RRset's name might not be the query name.

All of the "business logic" of resolution is encapsulated in this
class, allowing us to have multiple resolve() implementations
using different I/O schemes without copying all of the
complicated logic.
This class is a "friend" to dns.resolver.Resolver and manipulates
resolver data structures directly.

Resolvers (DDR). If successful, the resolver will subsequently use
DNS-over-HTTPS or DNS-over-TLS for future queries.
*lifetime*, a float, is the maximum time to spend attempting DDR. The default
is 5 seconds.
If the SVCB query is successful and results in a non-empty list of nameservers,
then the resolver's nameservers are set to the returned servers in priority
order.
The current implementation does not use any address hints from the SVCB record,
nor does it resolve addresses for the SCVB target name, rather it assumes that
the bootstrap nameserver will always be one of the addresses and uses it.
A future revision to the code may offer fuller support. The code verifies that
the bootstrap nameserver is in the Subject Alternative Name field of the
TLS certficate.

Raises ``dns.resolver.NoRootSOA`` if there is no SOA RR at the DNS
