LazyContainer

Struct LazyContainer 

Source 
pub struct LazyContainer { /* private fields */ }
Expand description

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§

Source§

impl LazyContainer

Source

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.

Source

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

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