Struct NegationScopeVisitor 

struct NegationScopeVisitor {
    in_negation: bool,
    found_scope_in_negation: bool,
}

A struct that visits a selector and determines if there is a :scope component nested withing a negation. eg. :not(:scope)

Fields

in_negation: bool

Have we found a negation list yet

found_scope_in_negation: bool

Have we found a :scope inside a negation yet

Implementations

impl NegationScopeVisitor

fn new() -> Self

Create a new NegationScopeVisitor

fn traverse_selector( self, selector: &Selector<<NegationScopeVisitor as SelectorVisitor>::Impl>, ) -> bool

fn traverse_dependency(self, dependency: &Dependency) -> bool

Traverse all the next dependencies in an outer dependency until we reach

1. :not(* :scope *)
2. a scope or relative dependency
3. the end of the chain of dependencies Return whether or not we encountered :not(* :scope *)

Trait Implementations

impl SelectorVisitor for NegationScopeVisitor

type Impl = SelectorImpl

The selector implementation this visitor wants to visit.

fn visit_attribute_selector( &mut self, _namespace: &NamespaceConstraint<&<Self::Impl as SelectorImpl>::NamespaceUrl>, _local_name: &<Self::Impl as SelectorImpl>::LocalName, _local_name_lower: &<Self::Impl as SelectorImpl>::LocalName, ) -> bool

Visit an attribute selector that may match (there are other selectors that may never match, like those containing whitespace or the empty string).

fn visit_simple_selector(&mut self, component: &Component<Self::Impl>) -> bool

Visit a simple selector.

fn visit_relative_selector_list( &mut self, _list: &[RelativeSelector<Self::Impl>], ) -> bool

Visit a nested relative selector list. The caller is responsible to call visit into the internal selectors if / as needed.

fn visit_selector_list( &mut self, list_kind: SelectorListKind, list: &[Selector<Self::Impl>], ) -> bool

Visit a nested selector list. The caller is responsible to call visit into the internal selectors if / as needed.

fn visit_complex_selector( &mut self, _combinator_to_right: Option<Combinator>, ) -> bool

Visits a complex selector.
