Struct Dom 

pub struct Dom { /* private fields */ }

Arena-allocated DOM tree. All nodes live in a flat Vec, referenced by NodeId.

Implementations

impl Dom

pub fn new() -> Self

Create a new DOM with a Document node at index 0.

pub fn document(&self) -> NodeId

Get the document node ID.

pub fn get(&self, id: NodeId) -> Option<&Node>

Get a reference to a node by ID.

pub fn get_mut(&mut self, id: NodeId) -> Option<&mut Node>

Get a mutable reference to a node by ID.

pub fn len(&self) -> usize

Total number of live nodes.

pub fn is_empty(&self) -> bool

pub fn create_element( &mut self, name: QualName, attrs: Vec<Attribute>, ) -> NodeId

pub fn create_text(&mut self, text: String) -> NodeId

pub fn create_comment(&mut self, text: String) -> NodeId

pub fn create_document_fragment(&mut self) -> NodeId

pub fn create_shadow_root( &mut self, host: NodeId, mode: ShadowRootMode, ) -> NodeId

Create a shadow root and attach it to the given host element.

pub fn allocate_pi(&mut self, target: String, data: String) -> NodeId

pub fn create_doctype( &mut self, name: String, public_id: String, system_id: String, ) -> NodeId

pub fn append_child(&mut self, parent: NodeId, child: NodeId)

Append child as the last child of parent.

Cycle-safe: if child is an ancestor of parent, the mutation is a no-op.

pub fn insert_before( &mut self, parent: NodeId, child: NodeId, reference: NodeId, )

Insert child before reference (which must be a child of parent).

pub fn detach(&mut self, id: NodeId)

Detach a node from its parent (but keep it in the arena).

pub fn remove(&mut self, id: NodeId)

Remove a node from the arena entirely (recycles its slot).

pub fn reparent_children(&mut self, source: NodeId, target: NodeId)

Move all children of source to become children of target.

pub fn children(&self, parent: NodeId) -> Vec<NodeId>

Iterate over child node IDs.

pub fn child_elements(&self, parent: NodeId) -> Vec<NodeId>

Iterate over child element node IDs (skip text/comment nodes).

pub fn text_content(&self, id: NodeId) -> String

Get text content of a subtree.

pub fn set_text_content(&mut self, id: NodeId, text: &str)

Set text content: remove all children, add a single text node.

pub fn get_element_by_id(&self, id_value: &str) -> Option<NodeId>

Find an element by ID attribute (tree walk from document root).

pub fn get_elements_by_tag_name(&self, root: NodeId, tag: &str) -> Vec<NodeId>

Find elements by tag name (case-insensitive).

pub fn get_elements_by_class_name( &self, root: NodeId, class: &str, ) -> Vec<NodeId>

Find elements by class name.

pub fn serialize_html(&self, id: NodeId) -> String

Serialize a subtree as HTML.

pub fn serialize_inner_html(&self, id: NodeId) -> String

Serialize children of a node as HTML (for innerHTML getter).

pub fn merge_subtree(&mut self, source: &Dom, source_root: NodeId) -> NodeId

Copy a subtree from another Dom into this one. Returns the new root NodeId.

pub fn node_type(&self, id: NodeId) -> u32

Get the node type number (matches DOM spec nodeType).

Trait Implementations

impl Debug for Dom

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Dom

fn default() -> Self

Returns the “default value” for a type.
