Struct Tree 

pub struct Tree {
    pub app_name: String,
    pub pid: Option<u32>,
    pub screen_size: (u32, u32),
    /* private fields */
}

A snapshot of an application’s accessibility tree.

The tree is a flattened snapshot — nodes are stored in DFS order and reference each other by internal indices. Navigation is done through Tree methods that accept &Node references.

Fields

app_name: String

Application name

pid: Option<u32>

Process ID. None for multi-app queries.

screen_size: (u32, u32)

Screen dimensions at capture time (width, height)

Implementations

impl Tree

pub fn new( app_name: String, pid: Option<u32>, screen_size: (u32, u32), nodes: Vec<Node>, ) -> Tree

Create a new Tree from a list of nodes.

pub fn get(&self, index: u32) -> Option<&Node>

Get a node by its internal index. Primarily for FFI consumers.

pub fn root(&self) -> &Node

Get the root node.

pub fn parent(&self, node: &Node) -> Option<&Node>

Get the parent of a node.

pub fn children(&self, node: &Node) -> Vec<&Node>

Get direct children of a node.

pub fn subtree(&self, node: &Node) -> Vec<&Node>

Get the subtree rooted at a node (including the node itself).

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

Iterate all nodes.

pub fn query(&self, selector_str: &str) -> Result<Vec<&Node>, Error>

Query nodes matching a CSS-like selector string.

pub fn dump(&self) -> String

Render the tree as an indented text representation for debugging.

pub fn len(&self) -> usize

Get the number of nodes in the tree.

pub fn is_empty(&self) -> bool

Check if the tree is empty.

Trait Implementations

impl Debug for Tree

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

Formats the value using the given formatter.
