Struct CaretBlink 

pub struct CaretBlink {
    pub visible: bool,
    pub phase: Instant,
    pub period: Duration,
}

Caret blink phase, shared main-world resource (W2 text-editing core).

• Toggled by lumen_text_edit::caret_blink on a Self::period cadence while a TextInput holds focus; reset to visible on any edit or caret move.
• Read by extract_text: when visible is false the caret byte is withheld from the extracted run, so the renderer paints no bar.
• Absent resource => caret always visible (headless / embedder path).

Fields

visible: bool

Whether the caret is currently in the visible half of the phase.

phase: Instant

Start of the current blink phase; elapsed time against Self::period selects the half-cycle.

period: Duration

Half-cycle duration (visible for one period, hidden for the next). Qt’s default is ~530 ms; this default is the single Rust fallback for the CSS caret-blink property, which overwrites this field directly (there is no per-entity blink state to route a per-element override through).

Implementations

impl CaretBlink

pub fn reset(&mut self)

Restart the phase at “visible” (called on focus change and on every edit / caret move so the caret never blinks mid-keystroke).

Trait Implementations

impl Clone for CaretBlink

fn clone(&self) -> CaretBlink

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for CaretBlink

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::SparseSet

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 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.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

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]

impl Debug for CaretBlink

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

Formats the value using the given formatter.

impl Default for CaretBlink

fn default() -> Self

Returns the “default value” for a type.

impl Copy for CaretBlink

impl Resource for CaretBlink

where Self: Send + Sync + 'static,
