Struct NativeSwitchView 

pub struct NativeSwitchView { /* private fields */ }

A real android.widget.Switch rendered from pure Rust — a controlled component (docs/CODE_STANDARDS.md’s Interaction Semantics): the app owns checked, and a user toggle only ever arrives through Self::on_toggle as a requested value. Build one with native_switch.

Implementations

impl NativeSwitchView

pub fn enabled(self, enabled: bool) -> Self

View.setEnabled — default true.

pub fn content_description(self, label: impl Into<String>) -> Self

The TalkBack label.

pub fn size(self, width: f64, height: f64) -> Self

Explicit slot size — see [resolve_size]’s doc for the no-call fallback.

pub fn on_toggle(self, handler: impl Fn(bool) + Send + Sync + 'static) -> Self

Fires with the requested checked state on a user toggle — the app confirms (or rejects) it by feeding checked back through the next build, the controlled-component contract every interactive frust widget follows.

Trait Implementations

impl Clone for NativeSwitchView

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for NativeSwitchView

type State = u64

The retained local state this component owns across rebuilds.

fn init(&self) -> SlotId

Create the component’s initial local state. Runs exactly once, when the ComponentWidget is first built, under the component’s Owner (so on_cleanup/provide_context registered here bind to that owner).

fn build(&self, state: &mut SlotId) -> AnyView<SlotId>

Produce the component’s subtree from its current local state.

impl<Outer: 'static> View<Outer> for NativeSwitchView

type Element = ComponentWidget<NativeSwitchView>

The retained widget this view produces.

fn build(&self, ctx: &mut BuildCtx<'_>) -> Self::Element

Materialise a fresh widget for this view.

fn rebuild( &self, prev: &Self, element: &mut Self::Element, ctx: &mut BuildCtx<'_>, ) -> ChangeFlags

Reconcile prev (the previous view of the same type) against the live element, mutating it in place and reporting what changed.

fn teardown(&self, element: &mut Self::Element, ctx: &mut BuildCtx<'_>)

Tear down element when this view is being removed.

fn message(&self, _element: &mut Self::Element, _state: &mut State)

Deliver an event message to this view, mutating application state.
