How many instances of t are there in:
Authority is responsible for storing the resource records for a particular zone.
Authorities default to DNSClass IN. The ZoneType specifies if this should be treated as the start of authority for the zone, is a slave, or a cached zone.
Creates a new Authority.
origin - The zone Name being created, this should match that of the RecordType::SOA record.
records - The HashMap of the initial set of records in the zone.
zone_type - The type of zone, i.e. is this authoritative?
allow_update - If true, then this zone accepts dynamic updates.
The new Authority.
Returns the SOA of the authority.
Note This will only return the SOA, if this is fullfilling a request, a standard lookup should be used, see get_soa_secure(), which will optionally return RRSIGs.
Inserts or updates a Record depending on its existence in the authority.
Guarantees that SOA, CNAME only has one record, will implicitly update if they already exist.
record - The Record to be inserted or updated.
serial - Current serial number to be recorded against updates.
Ok() on success or Err() with the ResponseCode associated with the error.
Takes the UpdateMessage, extracts the Records, and applies the changes to the record set.
update - The UpdateMessage records will be extracted and used to perform the update actions as specified in the above RFC.
true if any of additions, updates or deletes were made to the zone, false otherwise. Err is returned in the case of bad data, etc.
Using the specified query, perform a lookup against this zone.
query - the query to perform the lookup with.
is_secure - if true, then RRSIG records (if this is a secure zone) will be returned.
Returns a vectory containing the results of the query, it will be empty if not found. If is_secure is true, in the case of no records found then NSEC records will be returned.
Looks up all Resource Records matching the giving Name and RecordType.
name - The Name, label, to lookup.
rtype - The RecordType, to lookup. RecordType::ANY will return all records matching name. RecordType::AXFR will return all record types except RecordType::SOA due to the requirements that on zone transfers the RecordType::SOA must both preceed and follow all other records.
is_secure - If the DO bit is set on the EDNS OPT record, then return RRSIGs as well.
None if there are no matching records, otherwise a Vec containing the found records.
