Reasons a borrowed offset or value array failed structural validation.

Performance

Formatting is O(message length).

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.

Length

Length did not match count + 1.

Fields

expected: usize

Expected length (count + 1).

actual: usize

Observed length.

CountOverflow

expected_count + 1 overflowed usize, so no valid length exists.

Fields

count: usize

The element count whose successor overflowed.

FirstNonZero

offsets[0] was not zero.

Fields

actual: usize

Observed first offset.

NonMonotonic

offsets[index] < offsets[index - 1].

Fields

index: usize

Index where monotonicity failed.

previous: usize

Offset at index - 1.

actual: usize

Offset at index.

FinalMismatch

offsets[count] did not match value_len.

Fields

final_offset: usize

Observed final offset.

value_len: usize

Length of the values array.

ValueOutOfRange

A value at index was not less than the dense bound.

Fields

index: usize

Index of the offending value.

value: usize

Observed value.

bound: usize

Exclusive upper bound.

UsizeOverflow

A word’s value at index did not fit in usize on the current target.

Fields

index: usize

Slice position of the offending word.

Trait Implementations

impl Clone for OffsetIntegrityIssue

fn clone(&self) -> OffsetIntegrityIssue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OffsetIntegrityIssue

impl Debug for OffsetIntegrityIssue

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

Formats the value using the given formatter.

impl Display for OffsetIntegrityIssue

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

Formats the value using the given formatter.

impl Eq for OffsetIntegrityIssue

impl Error for OffsetIntegrityIssue

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 OffsetIntegrityIssue

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