fn get_better_ns_names(
rrs: &[ResourceRecord],
target: &DomainName,
current_match_count: usize,
) -> Option<(DomainName, HashSet<DomainName>)>Expand description
Given a set of RRs and a domain name we’re looking for, look for better matching NS RRs (by comparing the current match count). Returns the new matching superdomain and the nameserver hostnames.
