Struct style::stylesheets::scope_rule::ScopeSubjectMap

pub struct ScopeSubjectMap {
    buckets: SimpleBucketsMap<()>,
    any: bool,
}

A map containing simple selectors in subjects of scope selectors. This allows fast-rejecting scopes before running the full match.

Fields

buckets: SimpleBucketsMap<()>

any: bool
