Variants

NoError

No Error

FormErr

Format Error

ServFail

Server Failure

NXDomain

Non-Existent Domain

NotImp

Not Implemented

Refused

Query Refused

YXDomain

Name Exists when it should not. See rfc2136 and rfc6672.

YXRRSet

RR Set Exists when it should not. See rfc2136.

NXRRSet

RR Set that should exist does not. See rfc2136.

NotAuth

Note on error number 9 (NotAuth): This error number means either “Not Authoritative” rfc2136 or “Not Authorized” rfc2845. If 9 appears as the RCODE in the header of a DNS response without a TSIG RR or with a TSIG RR having a zero error field, then it means “Not Authoritative”. If 9 appears as the RCODE in the header of a DNS response that includes a TSIG RR with a non-zero error field, then it means “Not Authorized”.

NotZone

Name not contained in zone. See rfc2136.

DSOTYPENI

DSO-TYPE Not Implemented. See rfc8490.

Trait Implementations

impl Clone for Rcode

fn clone(&self) -> Rcode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rcode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Rcode

Defaults to Rcode::NoError.

fn default() -> Self

Returns the “default value” for a type.

impl Display for Rcode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl FromPrimitive for Rcode

fn from_i64(n: i64) -> Option<Self>

Converts an u64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_isize(n: isize) -> Option<Self>

Converts an isize to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i8(n: i8) -> Option<Self>

Converts an i8 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i16(n: i16) -> Option<Self>

Converts an i16 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i32(n: i32) -> Option<Self>

Converts an i32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i128(n: i128) -> Option<Self>

Converts an i128 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.
