type answer = {

rcode : Packet.rcode;
aa : bool;
answer : Packet.rr list;
authority : Packet.rr list;
additional : Packet.rr list;

}

Partially-marshalled query response; that is, it has been uncompacted from the compact Trie representation, but not yet rendered into a Cstruct.buf.

type filter = Name.t -> RR.rrset -> RR.rrset

type flush = Name.t -> Packet.rdata -> bool

val response_of_answer : ?mdns:bool -> Packet.t -> answer -> Packet.t

response_of_answer query answer is the Packet.t constructed from the answer to the query

val answer_of_response : ?preserve_aa:bool -> Packet.t -> answer

answer_of_response response is the answer corresponding to the upstream response for proxied or forwarded response.

val answer : 
  ?dnssec:bool ->
  ?mdns:bool ->
  ?filter:filter ->
  ?flush:flush ->
  Name.t ->
  Packet.q_type ->
  Trie.dnstrie ->
  answer

Answer a query about domain_name, given a query type q_type and a Trie of DNS data.

returns
the answer

val answer_multiple : 
  ?dnssec:bool ->
  ?mdns:bool ->
  ?filter:filter ->
  ?flush:flush ->
  Packet.question list ->
  Trie.dnstrie ->
  answer

Answer one or more questions given a Trie of DNS data.

returns
the answer

val create : 
  ?dnssec:bool ->
  id:int ->
  Packet.q_class ->
  Packet.q_type ->
  Name.t ->
  Packet.t

create ~id q_class q_type q_name creates a query for q_name with the supplied id, q_class, and q_type.
