}

Explicit accessibility role override. Maps to [accesskit::Role] through the From<A11yRole> for accesskit::Role impl in lumen-a11y-accesskit.

• Absent component: role derived from primitives (TextInput -> text input, Toggleable -> switch/checkbox, SliderValue -> slider, etc.).
• Present component: this value wins. Markup author can pin a role with role="dialog".

Variants

Button

Push button.

Link

Hyperlink.

TextInput

Single-line text input. Distinct from Self::TextArea so screen readers can announce single- vs multi-line behaviour.

TextArea

Multi-line text area.

Checkbox

Two-state checkbox.

Switch

Two-state on/off switch (checkbox semantics, switch presentation). Distinct from Self::Checkbox so assistive tech announces it as a switch (Role::Switch) - the role <switch> pins explicitly.

Radio

Single radio button. Pair with Self::RadioGroup.

RadioGroup

Container for a set of Self::Radio options.

Slider

Continuous bounded scalar control.

ProgressBar

Read-only progress indicator.

ComboBox

Drop-down combobox.

ListBox

Selectable list.

ListItem

One row in a Self::ListBox or Self::Tree.

MenuBar

Top-level menu bar (typically a window’s main menu).

Menu

Sub-menu container.

MenuItem

Action menu entry.

MenuItemCheckbox

Toggleable menu entry (checkbox-style).

MenuItemRadio

Menu entry inside a radio group.

Tab

Tab strip entry.

TabList

Container for Self::Tab entries.

TabPanel

Panel revealed by an active Self::Tab.

Tree

Tree container.

TreeItem

Single row inside a Self::Tree; use A11yLevel for depth.

Toolbar

Toolbar (typically a horizontal strip of Self::Buttons).

Dialog

Modal or modeless dialog.

AlertDialog

Alert dialog (modal, error-style).

Tooltip

Tooltip surface.

Status

Polite status region (live-region default).

Alert

Assertive alert region (live-region default).

Label

Visible label (typically associated via A11yRelations.labelled_by).

Heading

Heading; pair with A11yLevel for <h1>..<h6> depth.

Group

Generic grouping container (<fieldset>, <section>).

Region

Named landmark region (<aside>, <section role=region>).

Landmark

Page landmark (<header>, <footer>, <nav>, <main>).

Generic

Default generic container with no semantic role.

Trait Implementations

impl Clone for A11yRole

fn clone(&self) -> A11yRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for A11yRole

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn map_entities<M: EntityMapper>(this: &mut Self, mapper: &mut M)

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns [ComponentRelationshipAccessor] required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add [ComponentHook] for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert [ComponentHook] for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard [ComponentHook] for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove [ComponentHook] for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn [ComponentHook] for this Component if one is defined.

impl Debug for A11yRole

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

Formats the value using the given formatter.

impl From<&SliderValue> for A11yRole

fn from(_: &SliderValue) -> Self

Converts to this type from the input type.

impl From<&TextInput> for A11yRole

fn from(t: &TextInput) -> Self

Converts to this type from the input type.

impl From<&Toggleable> for A11yRole

fn from(_: &Toggleable) -> Self

Converts to this type from the input type.

impl PartialEq for A11yRole

fn eq(&self, other: &A11yRole) -> 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 Copy for A11yRole
