Struct LazyContainer 

pub struct LazyContainer { /* private fields */ }

A view wrapper that executes an arbitrary Layout implementation with reconstructable views, which can support lazy layouting.

Unlike FixedContainer, this container stores views as an AnyViews collection, allowing backends to reconstruct views on-demand for efficient rendering of large lists.

Implementations

impl LazyContainer

pub fn new<V: View>( layout: impl Layout + 'static, contents: impl Views<View = V> + 'static, ) -> Self

Wraps the supplied layout object and views into a lazy container view.

pub fn into_inner(self) -> (Box<dyn Layout>, AnyViews<AnyView>)

Returns the boxed layout object together with the collected child views.

pub fn as_parts(&self) -> (&dyn Layout, &AnyViews<AnyView>)

Returns borrowed access to the boxed layout and lazy child collection.

pub fn direction(&self) -> Computed<LayoutDirection>

Returns the resolved logical layout direction for lazy placement.
