EndOfBuffer

EndOfWindow

CursorAlreadyInWindow

CursorNotInWindow

CursorWindowError

Fields

window_end: usize

pos: usize

BufferTooShort(usize)

BadQuestionsCount(usize)

BadMessageType(MessageType)

BadResponseCode(RCode)

MessageTruncated

MessageTooLong(usize)

RecordsSectionOffsetUnknown(RecordsSection)

NoAnswer

UnsupportedType(Type)

Client API is supported for a subset of record types

UnsupportedClass(Class)

Client API is supported for a subset of record classes

Timeout

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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

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.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
