Trait Implementations

impl Default for TextInputPrimitiveHandler

fn default() -> Self

Returns the “default value” for a type.

impl PrimitiveHandler for TextInputPrimitiveHandler

fn uses_primary_focus(&self) -> bool

Whether this primitive owns one primary native focus target.

fn accessibility_actions( &self, _instance: &PrimitiveInstanceId, ) -> Vec<AccessibleAction>

Actions that the native primitive can perform for assistive technology.

fn perform_accessibility_action( &mut self, instance: &PrimitiveInstanceId, action: AccessibleAction, data: Option<&ActionData>, window: &mut Window, cx: &mut App, ) -> Result<(), String>

Perform one previously advertised accessibility action.

fn render( &mut self, instance: &PrimitiveInstance, events: &PrimitiveContext, theme: &PrimitiveTheme, window: &mut Window, cx: &mut App, ) -> Result<AnyElement, String>

Render the primitive into a native GPUI element.

fn unmount(&mut self, instance: &PrimitiveInstanceId)

Called when a previously mounted keyed primitive is no longer reachable.

fn effect_cost(&self, _instance: &PrimitiveInstance) -> usize

Return deterministic work units for this validated effect instance. Non-effect primitives ignore this value.

fn accessibility( &self, _instance: &PrimitiveInstanceId, _cx: &App, ) -> Option<PrimitiveAccessibilityProjection>

Contribute a bounded semantic summary for the retained primitive node. Native internals remain private; accessibility and automation receive only durable, already-presented values.

fn perform_key( &mut self, _instance: &PrimitiveInstanceId, _key: &str, ) -> Result<Option<PrimitiveSemanticProposal>, String>

Perform a native key semantic for automation using the same policy as the real focused control.

fn mount(&mut self, _instance: &PrimitiveInstance) -> Result<(), String>

Called once before the first render of a keyed lifecycle primitive.

fn update( &mut self, _previous: &PrimitiveInstance, _next: &PrimitiveInstance, ) -> Result<(), String>

Apply a validated prop/style/event snapshot to an existing keyed instance.

fn suspend(&mut self, _instance: &PrimitiveInstanceId, _cx: &mut App)

Prepare one retained native instance to cross into suspended state. Implementations must be idempotent because a failed peer is compensated and the whole operation may be retried.

fn resume(&mut self, _instance: &PrimitiveInstanceId, _cx: &mut App)

Prepare one suspended native instance to become active. The public view is not marked active until every primitive and the script transaction succeed.

fn commit_resume(&mut self, _instance: &PrimitiveInstanceId, _cx: &mut App)

Commit a successfully prepared resume after the script transaction has also succeeded. Activity time and event delivery may begin here.
