Errors encountered while decoding an SSZ-encoded byte slice.

Variants

UnexpectedEof

Input ended before the entire value could be read.

Fields

expected: usize

actual: usize

TrailingBytes

Input contained more bytes than the expected value occupies.

Fields

expected: usize

actual: usize

InvalidOffset

A length offset pointed outside the input slice or below the fixed region.

Fields

offset: usize

len: usize

fixed: usize

OffsetsNotMonotonic

Offsets must be monotonically non-decreasing.

Fields

prev: usize

curr: usize

BoundExceeded

A variable-length object exceeded its compile-time cap.

Fields

len: u64

bound: u64

LengthMismatch

A fixed-length vector was given the wrong number of elements.

Fields

expected: usize

actual: usize

InvalidSelector(u8)

Union/Option selector outside the allowed range.

InvalidBool(u8)

Bool byte was not 0 or 1.

MissingBitlistSentinel

Bitlist sentinel 1 bit was missing.

ExcessBits

Bitvector/Bitlist contained set bits beyond the declared length.

NotSorted

Sorted-collection keys were not strictly ascending.

ZeroNonZero

NonZeroU32 decoded as zero.

Custom(&'static str)

Custom decode error from a user implementation.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate 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 PartialEq for DecodeError

fn eq(&self, other: &DecodeError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
