Variants

ConnectionClosed

Connection was already closed.

OptTooLong

The OPT record has become too long.

MessageBuilderPushError

PushError from MessageBuilder.

MessageParseError

ParseError from Message.

RedundantTransportNotFound

Underlying transport not found in redundant connection

FormError

The message violated some constraints.

ShortMessage

Octet sequence too short to be a valid DNS message.

StreamLongMessage

Message too long for stream transport.

StreamIdleTimeout

Stream transport closed because it was idle (for too long).

StreamReceiveError

Error receiving a reply.

StreamReadError(Arc<Error>)

Reading from stream gave an error.

StreamReadTimeout

Reading from stream took too long.

StreamTooManyOutstandingQueries

Too many outstand queries on a single stream transport.

StreamWriteError(Arc<Error>)

Writing to a stream gave an error.

StreamUnexpectedEndOfData

Reading for a stream ended unexpectedly.

WrongReplyForQuery

Reply does not match the query.

NoTransportAvailable

No transport available to transmit request.

Dgram(Arc<QueryError>)

An error happened in the datagram transport.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
