Struct IndexedStackView 

pub struct IndexedStackView<State>
where
    State: 'static,
{ /* private fields */ }

A declarative indexed stack. See IndexedStack and the module docs.

Implementations

impl<State> IndexedStackView<State>

where State: 'static,

pub fn child<V>(self, view: V) -> IndexedStackView<State>

where V: View<State>,

Append a child after the existing ones. Accepts any View.

pub fn children<M>( self, children: impl ViewSeq<State, M>, ) -> IndexedStackView<State>

Append every element of children after the existing ones, in order.

Accepts any ViewSeq (Vec, array, tuple, Option, nested, or views(iter)); tuples are positional and a None element drops its slot.

pub fn when( self, cond: bool, f: impl FnOnce(IndexedStackView<State>) -> IndexedStackView<State>, ) -> IndexedStackView<State>

Apply f to the builder only when cond is true.

pub fn when_some<T>( self, opt: Option<T>, f: impl FnOnce(IndexedStackView<State>, T) -> IndexedStackView<State>, ) -> IndexedStackView<State>

Apply f with the contained value when opt is Some.

Trait Implementations

impl<State> View<State> for IndexedStackView<State>

where State: 'static,

type Element = IndexedStackWidget

The retained widget this view produces.

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

Materialise a fresh widget for this view.

fn rebuild( &self, prev: &IndexedStackView<State>, element: &mut IndexedStackWidget, 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 IndexedStackWidget, 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.
