}

A normalized enum of interactions that can be performed on accessibility elements.

Variants

Press = 0

Click / tap / invoke

Focus = 1

Set keyboard focus

SetValue = 2

Set text content or numeric value.

Accepts ActionData::Value(String) for text or ActionData::NumericValue(f64) for numeric values.

Platform note: On Linux AT-SPI, the Value interface only supports numeric values (f64). Setting text requires the Text interface.

Toggle = 3

Toggle a checkbox or switch

Expand = 4

Expand a collapsible element

Collapse = 5

Collapse an expanded element

Select = 6

Select an item in a list or table

ShowMenu = 7

Show context menu or dropdown

ScrollIntoView = 8

Scroll element into visible area.

Platform note: No-op on macOS (no direct AX equivalent).

Scroll = 9

Scroll by a given amount and direction.

Accepts ActionData::ScrollAmount { direction, amount }. Amount is in logical scroll units (≈ one mouse wheel notch).

Platform mapping:

• macOS: CGEventCreateScrollWheelEvent with pixel delta (1 unit ≈ 10px)
• Windows: IUIAutomationScrollPattern.Scroll() with SmallIncrement repeated
• Linux: AT-SPI Component.ScrollTo with edge alignment

Increment = 10

Increment a slider or spinner

Decrement = 11

Decrement a slider or spinner

Blur = 12

Remove keyboard focus from element

SetTextSelection = 13

Select a text range within an editable element.

Accepts ActionData::TextSelection { start, end }.

TypeText = 14

Insert text at the current cursor position via the accessibility API.

Uses platform text-editing interfaces (AXSelectedText on macOS, EditableText.InsertText on Linux, ValuePattern on Windows) — never synthetic keyboard events.

Accepts ActionData::Value(String).

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<'de> Deserialize<'de> for Action

fn deserialize<__D>( __deserializer: __D, ) -> Result<Action, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Action

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

Formats the value using the given formatter.

impl Hash for Action

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.

impl Serialize for Action

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Action

impl Eq for Action

impl StructuralPartialEq for Action
