Trait embedded_layout::view_group::ViewGroup

pub trait ViewGroup: View {
    // Required methods
    fn len(&self) -> usize;
    fn at(&self, idx: usize) -> &dyn View;
    fn at_mut(&mut self, idx: usize) -> &mut dyn View;
}

A set of operations required to implement View containers.

fn at(&self, idx: usize) -> &dyn View

Returns a shared reference the View object at position idx.

fn at_mut(&mut self, idx: usize) -> &mut dyn View

Returns an exclusive reference to the View object at position idx.
