The status code of the response to a query.

RFC 1035, DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION, November 1987

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.

Implementations§

source§

impl ResponseCode

source

pub fn low(self) -> u8

returns the lower 4 bits of the response code (for the original header portion of the code)

source

pub fn high(self) -> u8

returns the high 8 bits for the EDNS portion of the response code

source

pub fn from_low(low: u8) -> Self

DNS can not store the entire space of ResponseCodes in 4 bit space of the Header, this function allows for a initial value of the first 4 bits to be set.

After the EDNS is read, the entire ResponseCode (12 bits) can be reconstructed for the full ResponseCode.

source

pub fn from(high: u8, low: u8) -> Self

Combines the EDNS high and low from the Header to produce the Extended ResponseCode

source

pub fn to_str(self) -> &'static str

Transforms the response code into the human message
