Struct Tree 

pub struct Tree { /* private fields */ }

Retained tree store. Holds the current root node (if any) and supports full replacement (snapshot) and incremental patch application.

Implementations

impl Tree

pub fn new() -> Self

pub fn snapshot(&mut self, root: TreeNode)

Replace the entire tree with a new root (snapshot).

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

Return a reference to the current root, if any.

pub fn find_window(&self, toddy_id: &str) -> Option<&TreeNode>

Find a window node by its toddy ID, searching the entire tree recursively.

pub fn window_ids(&self) -> Vec<String>

Collect the IDs of all window nodes in the tree (recursive search).

pub fn apply_patch(&mut self, ops: Vec<PatchOp>)

Apply a sequence of patch operations to the tree.

Operations are applied sequentially. If one operation fails, it is skipped with a warning and subsequent operations are still applied. This means a partial failure can leave the tree in an intermediate state. The host should treat patch sequences as best-effort and use Snapshot for full-state recovery when needed.

Trait Implementations

impl Debug for Tree

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

Formats the value using the given formatter.

impl Default for Tree

fn default() -> Tree

Returns the “default value” for a type.
