Trait Implementations

impl ElementSplice for VecSplice<'_, '_, WidgetPod<Box<dyn Widget>>>

fn push(&mut self, element: WidgetPod<Box<dyn Widget>>)

Insert a new element at the current index in the resulting collection (and increment the index by 1)

fn mutate(&mut self) -> WidgetMut<'_, Box<dyn Widget>>

Mutate the next existing element, and add it to the resulting collection (and increment the index by 1)

fn delete(&mut self, n: usize)

Delete the next n existing elements (this doesn’t change the index)

fn len(&self) -> usize

Current length of the elements collection
