Required Methods

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

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

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

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

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

fn is_html_element_in_html_document(&self) -> bool

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

fn get_namespace(&self) -> &Self::Impl::BorrowedNamespace

fn match_non_ts_pseudo_class(&self, pc: Self::Impl::NonTSPseudoClass) -> bool

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

fn has_class(&self, name: &Self::Impl::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.

fn each_class<F>(&self, callback: F) where F: FnMut(&Self::Impl::ClassName)

Provided Methods

fn insert_flags(&self, _flags: ElementFlags)

Add flags to the element. See the ElementFlags docs for details.

This may be called while the element or one of its children is being matched. Therefore the implementation must be thread-safe if children may be matched in parallel.
