Enum DeltaDecodeReason 

pub enum DeltaDecodeReason {
    EmptyReference,
    DataLengthMismatch {
        data_len: usize,
        reference_len: usize,
    },
    ReferenceIndexOutOfBounds {
        index: usize,
        length: usize,
    },
    DataIndexOutOfBounds {
        index: usize,
        length: usize,
    },
    Unknown,
}

Represents why a delta decode operation failed.

Using an enum instead of String allows for zero-allocation error construction and programmatic error inspection.

Variants

EmptyReference

The reference bytes were empty.

DataLengthMismatch

The data length is not a multiple of the reference length.

Fields

data_len: usize

The length of the data buffer.

reference_len: usize

The length of the reference buffer.

ReferenceIndexOutOfBounds

The reference bytes index was out of bounds.

Fields

index: usize

The index that was out of bounds.

length: usize

The length of the reference buffer.

DataIndexOutOfBounds

The data index was out of bounds.

Fields

index: usize

The index that was out of bounds.

length: usize

The length of the data buffer.

Unknown

An unknown or unexpected error occurred during delta decoding.

This variant is used as a fallback when the underlying error cannot be mapped to a more specific reason (e.g., when downcasting fails).

Trait Implementations

impl Clone for DeltaDecodeReason

fn clone(&self) -> DeltaDecodeReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeltaDecodeReason

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

Formats the value using the given formatter.

impl Display for DeltaDecodeReason

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

Formats the value using the given formatter.

impl Hash for DeltaDecodeReason

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DeltaDecodeReason

fn eq(&self, other: &DeltaDecodeReason) -> 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.
