Implementations§

Source§

impl Node

Source

pub const fn data(&self) -> &NodeData

Return a reference to this node’s node-type-specific data.

Source

pub const fn as_element(&self) -> Option<&ElementData>

If this node is an element, return a reference to element-specific data.

Source

pub const fn as_document(&self) -> Option<&Cell<QuirksMode>>

If this node is a document, return a reference to element-specific data.

Source

pub const fn as_text(&self) -> Option<&RefCell<StrTendril>>

If this node is a text node, return a reference to its contents.

Source

pub fn parent(&self) -> Option<NodeRef>

Return a reference to the parent node, unless this node is the root of the tree.

Source

pub fn first_child(&self) -> Option<NodeRef>

Return a reference to the first child of this node, unless it has no child.

Source

pub fn last_child(&self) -> Option<NodeRef>

Return a reference to the last child of this node, unless it has no child.

Source

pub fn previous_sibling(&self) -> Option<NodeRef>

Return a reference to the previous sibling of this node, unless it is a first child.

Source

pub fn next_sibling(&self) -> Option<NodeRef>

Return a reference to the next sibling of this node, unless it is a last child.

Source

pub fn detach(&self)

Detach a node from its parent and siblings. Children are not affected.

To remove a node and its descendants, detach it and drop any strong reference to it.
