Implementations

impl DnsRcode

pub fn encode(&self) -> u8

Encodes a DnsRcode as a byte (actually only the lower four bits are used). Note that for RCODEs BADVERSBADSIG and following only the lower four bits are encoded; the upper eight bits need to be encoded in an OPT record in the additional section of the DNS message.

pub fn parse(val: u16) -> Result<DnsRcode, ParseError>

Parses an encoded DnsRcode from a twelve bit value. If EDNS is used, the upper eight bits are stored in the OPT entry of the additional section and the lower four bits are stored in the DnsHeader. Returns an error if the given value does not represent a valid DNS RCODE.
