pub struct List { /* private fields */ }Expand description
A view for creating a list of items from an iterable signal.
Implementations§
Source§impl List
impl List
Sourcepub fn new<S, V, T>(
cx: &mut Context,
list: S,
item_content: impl 'static + Fn(&mut Context, usize, Signal<T>),
) -> Handle<'_, Self>
pub fn new<S, V, T>( cx: &mut Context, list: S, item_content: impl 'static + Fn(&mut Context, usize, Signal<T>), ) -> Handle<'_, Self>
Creates a new List view from a reactive or static list of values.
list accepts any Res<V> source where V derefs to [T] — for example a
Signal<Vec<T>> for a reactive list, or a plain Vec<T> for a static list.
The list creates and manages internal signals for each item automatically.
Value changes to existing items update their internal signals with zero entity rebuilds.
Structural changes (add/remove/reorder) are handled by diffing values and rebuilding from the first changed position.

fn into_any(self: Box<T>) -> Box<dyn Any>
Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
