0: u16

Special class for OPT Version, it was overloaded for EDNS - RFC 6891 From the RFC: Values lower than 512 MUST be treated as equal to 512

Implementations

use trust_dns_proto::rr::dns_class::DNSClass;

let var = DNSClass::from_u16(1).unwrap();
assert_eq!(DNSClass::IN, var);

Return the OPT version from value
