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

Pointer points to an index within or after the current label

Fields

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

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.

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)>

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.

impl From<DecodeError> for ProtoError

fn from(err: DecodeError) -> Self

Converts to this type from the input type.

impl Copy for DecodeError
