Required Methods

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

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

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.

Clears the relevant ElementFlags. This is not called from rust-selectors, but provided as part of the Element interface since it makes sense.
