Expand description
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§
sourcetype Impl: SelectorImpl
type Impl: SelectorImpl
The selector implementation this visitor wants to visit.
Provided Methods§
sourcefn 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_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).
sourcefn visit_simple_selector(&mut self, _: &Component<Self::Impl>) -> bool
fn visit_simple_selector(&mut self, _: &Component<Self::Impl>) -> bool
Visit a simple selector.
sourcefn visit_complex_selector(
&mut self,
_combinator_to_right: Option<Combinator>,
) -> bool
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.
