Which WHATWG “parse error” (§13.2.2) occurred. Variant names mirror the spec’s own kebab-case error identifiers, translated to PascalCase. Only variants this crate actually detects and reports exist — no catch-all/string-payload variant, so matching on a specific kind stays meaningful. #[non_exhaustive] because more variants are expected in follow-up phases (plan/07-parse-errors.md: tokenizer-level errors only so far — tree-construction-level errors, e.g. stray end tags across the whole document, are follow-up work, not yet represented here) — adding one later must not be a breaking change for any caller matching on this type.

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.

Trait Implementations

impl Clone for ParseErrorKind

fn clone(&self) -> ParseErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ParseErrorKind

impl Debug for ParseErrorKind

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

Formats the value using the given formatter.

impl Display for ParseErrorKind

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

A short, human-readable description — not a transcription of any particular consumer’s exact wording (e.g. not vnu’s), just a plain-English description of the WHATWG condition this variant names. Consumers that need their own phrasing should match on ParseErrorKind directly instead of parsing this string.

impl Eq for ParseErrorKind

impl PartialEq for ParseErrorKind

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

Equality operator ==.

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

Inequality operator !=.
