[−][src]Enum trust_dns::op::ResponseCode
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.

Methods
impl ResponseCode
[src]
pub fn low(self) -> u8
[src]
returns the lower 4 bits of the response code (for the original header portion of the code)
pub fn high(self) -> u16
[src]
returns the high 12 bits for the edns portion of the response code
pub fn from(high: u8, low: u8) -> ResponseCode
[src]
Combines the EDNS high and low from the Header to produce the Extended ResponseCode
pub fn to_str(self) -> &'static str
[src]
Transforms the response code into the human message
