Struct NativeSpinnerView 

pub struct NativeSpinnerView { /* private fields */ }

A real indeterminate activity indicator rendered from pure Rust — display-only (no listener, no .interactive()). Build one with native_spinner.

Implementations

impl NativeSpinnerView

pub fn size_class(self, size_class: NativeSpinnerSize) -> Self

The spinner’s size — see NativeSpinnerSize.

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

View.setEnabled — Android only; the other two arms have no enabled property on this control at all (crate::controls::spinner’s module doc’s enabled section). Default true.

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

The TalkBack/VoiceOver label.

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

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

Trait Implementations

impl Clone for NativeSpinnerView

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 NativeSpinnerView

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 NativeSpinnerView

type Element = ComponentWidget<NativeSpinnerView>

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.
