}

Span validation failure.

Variants

OutOfBounds

A range does not satisfy start <= end <= summary length.

Fields

index: usize

Index of the offending span.

InvalidUtf8Boundary

A range boundary splits a UTF-8 scalar.

Fields

index: usize

Index of the offending span.

OverlapOrUnordered

A span starts before the prior span ends.

Fields

index: usize

Index of the offending span.

UncoveredNonWhitespace

Non-whitespace summary text has no covering span.

Fields

byte: usize

Byte offset of the uncovered character.

AuthorityMismatch

Cached max authority disagrees with recomputed authority.

Fields

index: usize

Index of the offending span.

expected: SourceAuthority

Recomputed authority.

observed: SourceAuthority

Stored authority.

Implementations

impl SummarySpanError

pub const fn invariant(&self) -> &'static str

Stable invariant name for operator-facing verification.

Trait Implementations

impl Clone for SummarySpanError

fn clone(&self) -> SummarySpanError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SummarySpanError

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

Formats the value using the given formatter.

impl PartialEq for SummarySpanError

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