Expand description
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
impl ResponseCode
sourcepub fn low(self) -> u8
pub fn low(self) -> u8
returns the lower 4 bits of the response code (for the original header portion of the code)
sourcepub fn from_low(low: u8) -> Self
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.
