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

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InsufficientBytes

Insufficient data in the buffer for a read operation

InvalidPreviousIndex

slice_from was called with an invalid index

PointerNotPriorToLabel

Fields

idx: usize

index of the label containing this pointer

ptr: u16

location to which the pointer is directing

Pointer points to an index within or after the current label

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

Fields

label: usize

Start of the label that is overlaps

other: usize

Start of the other label

Overlapping labels

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

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

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

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

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

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

impl From<DecodeError> for ProtoError

fn from(err: DecodeError) -> Self

Performs the conversion.

impl Copy for DecodeError
