DESCRIPTION

       ldns_dnssec_data_chain
              Chain structure that contains all DNSSEC data needed to
              verify an rrset
              struct ldns_dnssec_data_chain_struct
              {
                   ldns_rr_list *rrset;
                   ldns_rr_list *signatures;
                   ldns_rr_type parent_type;
                   ldns_dnssec_data_chain *parent;
                   ldns_pkt_rcode packet_rcode;
                   ldns_rr_type packet_qtype;
                   bool packet_nodata;
              };

              typedef           struct           ldns_dnssec_data_chain_struct
              ldns_dnssec_data_chain;

       ldns_dnssec_data_chain_struct()

       ldns_dnssec_trust_tree
              Tree structure that contains the relation of DNSSEC data,
              and their cryptographic status.

              This tree is derived from a data_chain, and can be used
              to look whether there is a connection between an RRSET
              and a trusted key. The tree only contains pointers to the
              data_chain, and therefore one should *never* free() the
              data_chain when there is still a trust tree derived from
              that chain.

              Example tree:
                  key   key    key
                    \    |    /
                     \   |   /
                      \  |  /
                         ds
                         |
                        key
                         |
                        key
                         |
                         rr

              For each signature there is a parent; if the parent
              pointer is null, it couldn’t be found and there was no
              denial; otherwise is a tree which contains either a
              DNSKEY, a DS, or a NSEC rr
              struct ldns_dnssec_trust_tree_struct
              {
                   ldns_rr *rr;
                   /* the complete rrset this rr was in */
                   ldns_rr_list *rrset;
                   ldns_dnssec_trust_tree
              *parents[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS];
                   ldns_status
              parent_status[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS];
                   /** for debugging, add signatures too (you might want
                       those if they contain errors) */
                   ldns_rr
              *parent_signature[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS];
                   size_t parent_count;
              };

              typedef           struct           ldns_dnssec_trust_tree_struct
              ldns_dnssec_trust_tree;
