Struct CollectionRule 

pub struct CollectionRule<'a> {
    pub selector: Option<&'a QuerySelectorList<'a>>,
    pub collectors: SmallVec<[Atom<CsskitAtomSet>; 1]>,
    pub diagnostic: Option<(ResolvedDiagnosticLevel, &'a [DiagnosticComponent])>,
    pub diagnostic_stats: HashSet<u32>,
    pub conditions: Vec<'a, &'a WhenCondition<'a>>,
    pub parent_span: Span,
    /* private fields */
}

A rule that may be a selector-based rule or a standalone conditional diagnostic.

Fields

selector: Option<&'a QuerySelectorList<'a>>

The selector to match against CSS nodes (None for conditional diagnostics without selectors)

collectors: SmallVec<[Atom<CsskitAtomSet>; 1]>

The stat names to collect when nodes match

diagnostic: Option<(ResolvedDiagnosticLevel, &'a [DiagnosticComponent])>

Per-match diagnostics to emit (level, message template components)

diagnostic_stats: HashSet<u32>

Stats referenced in the diagnostic message (as atom bits) - need to be snapshotted

conditions: Vec<'a, &'a WhenCondition<'a>>

Conditions that must all be true for this rule to execute (AND conjunction) Empty vec means unconditional.

parent_span: Span

Span context for selectorless rules (from parent NodeRule or StyleSheet root) Used for bytes/lines collection when there’s no selector to match against
