Variants

NoError = 0

No Error.

No error condition.

FormatError = 1

Format Error.

The name server was unable to interpret the query.

ServerFailure = 2

Server Failure.

The name server was unable to process this query due to a problem with the name server.

NameError = 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.

NotImplemented = 4

Not Implemented

The name server does not support the requested kind of query.

Refused = 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.

Trait Implementations

impl Clone for ResponseCode

fn clone(&self) -> ResponseCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResponseCode

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

Formats the value using the given formatter.

impl Format for ResponseCode

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for ResponseCode

fn eq(&self, other: &ResponseCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u8> for ResponseCode

type Error = u8

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
