Enum DnsResponseCode 

pub enum DnsResponseCode {
    NoError,
    FormatError,
    ServerFailure,
    NameError,
    NotImplemented,
    Refused,
    Reserved(u8),
}

RCODE Response code - this 4 bit field is set as part of responses. The values have the following interpretation:

• 0 No error condition
• 1 Format error - The name server was unable to interpret the query.
• 2 Server failure - The name server was unable to process this query due to a problem with the name server.
• 3 Name Error - Meaningful only for responses from an authoritative name server, this code signifies that the domain name referenced in the query does not exist.
• 4 Not Implemented - The name server does not support the requested kind of query.
• 5 Refused - The name server refuses to perform the specified operation for policy reasons. For example, a name server may not wish to provide the information to the particular requester, or a name server may not wish to perform a particular operation (e.g., zone transfer) for particular data.
• 6-15 Reserved for future use.
