fn first_child_element(&self) -> Option<Self>

Skips non-element nodes

fn last_child_element(&self) -> Option<Self>

Skips non-element nodes

fn prev_sibling_element(&self) -> Option<Self>

fn is_html_element_in_html_document(&self) -> bool

fn get_local_name(&self) -> &<Self::Impl as SelectorImpl>::BorrowedLocalName

fn get_namespace(&self) -> &<Self::Impl as SelectorImpl>::BorrowedNamespaceUrl

Empty string for no namespace

fn attr_matches(
    &self,
    ns: &NamespaceConstraint<&<Self::Impl as SelectorImpl>::NamespaceUrl>,
    local_name: &<Self::Impl as SelectorImpl>::LocalName,
    operation: &AttrSelectorOperation<&<Self::Impl as SelectorImpl>::AttrValue>
) -> bool

fn match_non_ts_pseudo_class<F>(
    &self,
    pc: &<Self::Impl as SelectorImpl>::NonTSPseudoClass,
    context: &mut MatchingContext,
    flags_setter: &mut F
) -> bool where
    F: FnMut(&Self, ElementSelectorFlags), 

fn match_pseudo_element(
    &self,
    pe: &<Self::Impl as SelectorImpl>::PseudoElement,
    context: &mut MatchingContext
) -> bool

fn get_id(&self) -> Option<<Self::Impl as SelectorImpl>::Identifier>

fn has_class(&self, name: &<Self::Impl as SelectorImpl>::ClassName) -> bool

fn is_empty(&self) -> bool

Returns whether this element matches :empty.

That is, whether it does not contain any child element or any non-zero-length text node. See http://dev.w3.org/csswg/selectors-3/#empty-pseudo

fn is_root(&self) -> bool

Returns whether this element matches :root, i.e. whether it is the root element of a document.

Note: this can be false even if .parent_element() is None if the parent node is a DocumentFragment.

Provided Methods

fn pseudo_element_originating_element(&self) -> Option<Self>

The parent of a given pseudo-element, after matching a pseudo-element selector.

This is guaranteed to be called in a pseudo-element.
