Struct ShadowTree 

pub struct ShadowTree { /* private fields */ }

The shadow tree — owns all nodes.

Implementations

impl ShadowTree

pub fn new() -> Self

pub fn create_node( &mut self, id: NodeId, view_type: ViewType, initial_props: HashMap<String, PropValue>, )

Create a new node. Does NOT insert into the tree hierarchy — use append_child or insert_before for that.

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

Set the root node of the tree.

pub fn root(&self) -> Option<NodeId>

Get the root node ID.

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

Get a node by ID (immutable).

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

Get a node by ID (mutable).

pub fn update_props(&mut self, id: NodeId, diff: &PropsDiff)

Update props on a node. Changed props go into pending_props for the mount phase to consume.

pub fn append_child(&mut self, parent_id: NodeId, child_id: NodeId)

Append a child to a parent node.

pub fn insert_before( &mut self, parent_id: NodeId, child_id: NodeId, before_id: NodeId, )

Insert a child before another child in a parent’s children list.

pub fn remove_child(&mut self, parent_id: NodeId, child_id: NodeId)

Remove a child from its parent and the tree.

pub fn set_native_handle(&mut self, id: NodeId, handle: NativeHandle)

Set the native handle for a node (after platform bridge creates the view).

pub fn take_pending_props(&mut self, id: NodeId) -> PropsDiff

Take pending props (moves them out, leaving empty). Called by the mount phase after applying to native view.

pub fn children_of(&self, id: NodeId) -> &[NodeId]

Get the ordered children of a node.

pub fn ancestors(&self, id: NodeId) -> Vec<NodeId>

Walk ancestors from a node up to root (inclusive). Returns [root, …, parent, node_id].

pub fn len(&self) -> usize

Total number of nodes in the tree.

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = (&NodeId, &ShadowNode)>

Iterate all nodes (for DevTools snapshot).
