An error that can occur deep in a decoder This type is kept very small so that function that use it inline often

Variants

InsufficientBytes

Insufficient data in the buffer for a read operation

InvalidPreviousIndex

slice_from was called with an invalid index

PointerNotPriorToLabel

Pointer points to an index within or after the current label

Fields of PointerNotPriorToLabel

idx: usize

index of the label containing this pointer

ptr: u16

location to which the pointer is directing

LabelBytesTooLong(usize)

Label bytes exceeded the limit of 63

UnrecognizedLabelCode(u8)

An unrecognized label code was found

DomainNameTooLong(usize)

A domain name was too long

LabelOverlapsWithOther

Overlapping labels

Fields of LabelOverlapsWithOther

label: usize

Start of the label that is overlaps

other: usize

Start of the other label

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for DecodeError

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<DecodeError> for ProtoError

fn from(err: DecodeError) -> ProtoError

Performs the conversion.
