async fn zone_from_file<P: AsRef<Path>>(path: P) -> Result<Result<Zone, Error>>Expand description
Read a zone file.
If it has a SOA record, it is an authoritative zone: it may only have one SOA record, and all RRs must be subdomains of the SOA domain.
If it does not have a SOA record, it is a non-authoritative zone, and the root domain will be used for its apex.
