Struct NodeTree 

pub struct NodeTree { /* private fields */ }

Hierarchical node tree managing node lifecycles and parent-child relationships.

Nodes are stored with ownership in the tree; removing or dropping a node subtree automatically cleans up associated child nodes and script attachments.

Implementations

impl NodeTree

pub fn new() -> Self

Creates an empty NodeTree.

pub fn insert(&mut self, desc: NodeDesc) -> Result<()>

Inserts a node into the tree from a NodeDesc.

Validates node ID uniqueness and updates parent-child links. If no root has been established and the node has no parent, it is designated as the root.

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

pub fn contains(&self, id: &NodeId) -> bool

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

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

pub fn iter(&self) -> impl Iterator<Item = &Node>

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

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn remove(&mut self, id: &NodeId) -> Result<()>

pub fn reparent( &mut self, id: &NodeId, new_parent: Option<NodeId>, ) -> Result<()>

Trait Implementations

impl Debug for NodeTree

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

Formats the value using the given formatter.

impl Default for NodeTree

fn default() -> Self

Returns the “default value” for a type.
