Enum Action 

#[non_exhaustive]
pub enum Action {
    Activate,
    Focus,
    ToggleCheck,
    Increment,
    Decrement,
    Expand,
    Collapse,
    SetValue(String),
    SetSelection {
        anchor: usize,
        focus: usize,
    },
    ScrollIntoView,
    ShowContextMenu,
}

Requested by an assistive technology or the built-in screen reader. Consumed by the future Widget::perform_action hook, routed through the same CRDT-mutating path as handle_event.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Activate

A button press, a link follow, a menu-item invoke (ARIA/AT-SPI “click”).

Focus

ToggleCheck

Increment

Decrement

Expand

Tree item, combo box, disclosure.

Collapse

SetValue(String)

Text field, spin button.

SetSelection

Extended-grapheme indices into the accessible TextRun, matching AccessKit’s selectable-character model rather than Unicode scalars.

Fields

anchor: usize

Where the selection started.

focus: usize

Where it ends.

ScrollIntoView

ShowContextMenu

Trait Implementations

impl Clone for Action

fn clone(&self) -> Action

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Action

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

Formats the value using the given formatter.

impl PartialEq for Action

fn eq(&self, other: &Action) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
