Rich property bag attached to every crate::tree::A11yNode.

All fields are optional / defaulted so that callers only set what they need. The tree builder reads these fields and forwards them to the corresponding AccessKit setters.

Fields

description: Option<String>

Longer description of the widget (ARIA aria-describedby-equivalent text).

placeholder: Option<String>

Placeholder text for empty text inputs.

key_shortcut: Option<String>

Keyboard shortcut that activates this widget (e.g. "Ctrl+S").

disabled: bool

true if the widget is non-interactive.

expanded: Option<bool>

Expanded state: Some(true) = expanded, Some(false) = collapsed, None = not expandable.

selected: Option<bool>

Selected state: Some(true/false) = selectable, None = not selectable.

checked: Option<CheckedState>

Checked / toggle state; None = not checkable.

value_now: Option<f64>

Current numeric value (sliders, progress bars, spinners).

value_min: Option<f64>

Minimum allowed numeric value.

value_max: Option<f64>

Maximum allowed numeric value.

value_step: Option<f64>

Step increment for the numeric value.

text_value: Option<String>

Text content / string value of the node.

text_selection: Option<TextSelection>

Text selection (anchor + focus byte offsets).

labelled_by: Vec<NodeId>

Nodes that label this node (ARIA aria-labelledby).

described_by: Vec<NodeId>

Nodes that describe this node (ARIA aria-describedby).

controlled_by: Vec<NodeId>

Nodes that this node controls (ARIA aria-controls).

owns: Vec<NodeId>

Nodes that this node logically owns but that are not DOM descendants.

text_run_children: Vec<TextRunChild>

Synthesized text-run child segments for caret/selection exposure.

Populated by crate::tree::synthesize_text_run_children for text nodes that carry a TextSelection. Empty by default.

tab_index: Option<u32>

Explicit tab index controlling keyboard-focus order.

None / Some(0) = natural document order; Some(n) where n > 0 = explicit position (lower values receive focus first). Interpreted by crate::nav::TabOrder::compute.

Trait Implementations

impl Clone for A11yNodeProps

fn clone(&self) -> A11yNodeProps

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for A11yNodeProps

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

Formats the value using the given formatter.

impl Default for A11yNodeProps

fn default() -> A11yNodeProps

Returns the “default value” for a type.
