Struct LazyListScope 

pub struct LazyListScope<'a> { /* private fields */ }

Scope used to add lazily generated children to a lazy list.

Implementations

impl<'a> LazyListScope<'a>

pub fn items<F>(&mut self, count: usize, builder: F)

where F: Fn(usize) + Send + Sync + 'static,

Adds a batch of lazily generated items.

pub fn item<F>(&mut self, builder: F)

where F: Fn() + Send + Sync + 'static,

Add a single lazily generated item.

pub fn items_from_iter<I, T, F>(&mut self, iter: I, builder: F)

where I: IntoIterator<Item = T>, T: Send + Sync + 'static, F: Fn(usize, &T) + Send + Sync + 'static,

Adds lazily generated items from an iterator, providing both index and element reference.

The iterator is eagerly collected so it can be accessed on demand while virtualizing.

pub fn items_from_iter_values<I, T, F>(&mut self, iter: I, builder: F)

where I: IntoIterator<Item = T>, T: Send + Sync + 'static, F: Fn(&T) + Send + Sync + 'static,

Convenience helper for iterators when only the element is needed.
