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.

This type is internal to provider implementations. End users should use Node (returned by xa11y::app(), etc.) which wraps a Tree with navigation methods.

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<NodeData>, ) -> Self

Create a new Tree from a list of nodes.

pub fn get_data(&self, index: u32) -> Option<&NodeData>

Get a node’s data by its internal index.

pub fn root_data(&self) -> &NodeData

Get the root node data.

pub fn parent_data(&self, node: &NodeData) -> Option<&NodeData>

Get the parent of a node.

pub fn children_data(&self, node: &NodeData) -> Vec<&NodeData>

Get direct children of a node.

pub fn subtree_indices(&self, index: u32) -> Vec<u32>

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

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

Iterate all node data.

pub fn query_indices(&self, selector_str: &str) -> Result<Vec<u32>>

Query node indices matching a CSS-like selector string.

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

Query nodes matching a CSS-like selector string (returns NodeData refs).

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.
