Trait selectors::visitor::SelectorVisitor

pub trait SelectorVisitor {
    type Impl: SelectorImpl;

    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 { ... }
    fn visit_simple_selector(&mut self, _: &Component<Self::Impl>) -> bool { ... }
    fn visit_complex_selector(
        &mut self,
        _combinator_to_right: Option<Combinator>
    ) -> bool { ... }
}

A trait to visit selector properties.

All the visit_foo methods return a boolean indicating whether the traversal should continue or not.

Required Associated Types

type Impl: SelectorImpl

The selector implementation this visitor wants to visit.

Provided Methods

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<Self::Impl>) -> bool

Visit a simple selector.

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

Visits a complex selector.

Gets the combinator to the right of the selector, or None if the selector is the rightmost one.
