Required Methods

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

Get this node's parent node.

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

Get this node's first child.

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

Get this node's first child.

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

Get this node's previous sibling.

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

Get this node's next sibling.

fn owner_doc(&self) -> Self::ConcreteDocument

Get the owner document of this node.

fn is_in_document(&self) -> bool

Returns whether the node is attached to a document.

fn traversal_parent(&self) -> Option<Self::ConcreteElement>

Get this node's parent element from the perspective of a restyle traversal.

fn opaque(&self) -> OpaqueNode

Converts self into an OpaqueNode.

fn debug_id(self) -> usize

A debug id, only useful, mm... for debugging.

fn as_element(&self) -> Option<Self::ConcreteElement>
