Enum FindingKind 

pub enum FindingKind {
    DroppedDeclaration,
    UnsupportedSelector,
    MarginAsymmetryFlattened,
    UnsupportedTag,
    UnsupportedAttribute,
    FlattenedContent,
    SanitizedStyle,
}

What was dropped or coerced, in a single dimension. The transformer emits at most one finding per (node, kind) tuple, so a single element with three unsupported properties produces three findings.

Variants

DroppedDeclaration

A CSS declaration was recognised but its target has no Damascene equivalent — position: absolute, float: left, display: grid, vh/vw/fr units, etc. The author sees the declaration was dropped, not silently honoured.

UnsupportedSelector

A <style>-block selector form is outside the supported subset (descendant / child / sibling combinators, pseudo-classes, attribute selectors, namespace prefixes) and the whole rule was ignored. Reported by the selector parser at stylesheet-collect time.

MarginAsymmetryFlattened

Author-set margin-top / margin-bottom on siblings disagreed across pairs and was flattened to a single parent gap. The detail string spells out the values that collided.

UnsupportedTag

A tag (or a whole foreign-namespace subtree like inline <svg> / MathML <math>) was dropped because it has no equivalent and is not in the security-stripped set either — <video>, <audio>, <canvas>, <dialog>, <colgroup>, etc. Where the element can carry text (e.g. <video> fallback content), the contents are still flattened into the output; <form> / <fieldset> / <legend> are not in this set — they render as generic containers.

UnsupportedAttribute

An attribute was recognised but can’t be honoured — colspan / rowspan on table cells (cells render unmerged). The element itself still renders.

FlattenedContent

Block-level content appeared somewhere Damascene only renders inline runs (table cells), so its block structure was flattened — text survives, paragraph breaks and nested lists don’t.

SanitizedStyle

A <style> block or inline style="..." attribute was dropped because crate::HtmlOptions’s sanitize_styles is set. Lets a sanitizing embedder see that the input tried to style itself.

Trait Implementations

impl Clone for FindingKind

fn clone(&self) -> FindingKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FindingKind

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

Formats the value using the given formatter.

impl Eq for FindingKind

impl PartialEq for FindingKind

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