Struct LinuxProvider 

pub struct LinuxProvider { /* private fields */ }

Linux accessibility provider using AT-SPI2 over D-Bus.

Implementations

impl LinuxProvider

pub fn new() -> Result<Self>

Create a new Linux accessibility provider.

Connects to the AT-SPI2 bus. Falls back to the session bus if the dedicated AT-SPI bus is unavailable.

Trait Implementations

impl Provider for LinuxProvider

fn list_apps(&self) -> Result<Vec<ElementData>>

Enumerate top-level applications by listing direct children of the AT-SPI registry root — every running accessibility-enabled app registers a child accessible there. Apps with empty names are filtered out (toolkits sometimes register transient/system accessibles before the real app appears). PID resolution uses the AT-SPI Application interface, falling back to the D-Bus owner.

fn get_children( &self, element: Option<&ElementData>, ) -> Result<Vec<ElementData>>

Get direct children of an element.

fn find_elements_group( &self, root: &ElementData, group: &SelectorGroup, limit: Option<usize>, max_depth: Option<u32>, ) -> Result<Vec<ElementData>>

Search for elements matching any clause of a comma-separated selector group, scoped to root’s subtree.

fn get_parent(&self, element: &ElementData) -> Result<Option<ElementData>>

Get the parent of an element.

fn press(&self, element: &ElementData) -> Result<()>

Click / tap / invoke the element.

fn focus(&self, element: &ElementData) -> Result<()>

Set keyboard focus to the element.

fn blur(&self, element: &ElementData) -> Result<()>

Remove keyboard focus from the element.

fn toggle(&self, element: &ElementData) -> Result<()>

Toggle a checkbox or switch.

fn select(&self, element: &ElementData) -> Result<()>

Select an item in a list, tab group, or menu.

fn expand(&self, element: &ElementData) -> Result<()>

Expand a collapsible element (combo box, tree item, disclosure).

fn collapse(&self, element: &ElementData) -> Result<()>

Collapse an expanded element.

fn show_menu(&self, element: &ElementData) -> Result<()>

Show the element’s context menu or dropdown.

fn increment(&self, element: &ElementData) -> Result<()>

Increment a slider or spinner by one step.

fn decrement(&self, element: &ElementData) -> Result<()>

Decrement a slider or spinner by one step.

fn scroll_into_view(&self, element: &ElementData) -> Result<()>

Scroll the element into the visible area.

fn set_value(&self, element: &ElementData, value: &str) -> Result<()>

Set the text value of the element.

fn set_numeric_value(&self, element: &ElementData, value: f64) -> Result<()>

Set the numeric value of the element (slider, spinner).

fn type_text(&self, element: &ElementData, text: &str) -> Result<()>

Insert text at the current cursor position.

fn set_text_selection( &self, element: &ElementData, start: u32, end: u32, ) -> Result<()>

Select a text range (0-based character offsets).

fn perform_action(&self, element: &ElementData, action: &str) -> Result<()>

Perform an action by snake_case name.

fn subscribe(&self, element: &ElementData) -> Result<Subscription>

Subscribe to all accessibility events for an application.

fn find_elements( &self, root: &ElementData, selector: &Selector, limit: Option<usize>, max_depth: Option<u32>, ) -> Result<Vec<ElementData>, Error>

Search for elements matching a selector.

fn narrow_multi_segment( &self, candidates: Vec<ElementData>, segments: &[SelectorSegment], max_depth: u32, limit: Option<usize>, ) -> Result<Vec<ElementData>, Error>

Narrow candidates through remaining selector segments (Child/Descendant combinators), deduplicate, apply final :nth and limit.
