Struct Preview 

pub struct Preview(pub fn(&Reader<'_>, &PickedElement) -> Option<Picked>);

What a click on an element would pick for a reference field, in the part a reader reads, lit and drawn as it would be held (see crate::selectable::previewed); none if it would pick nothing. It follows from what the field picks (see Reference::accepts), so two previews count as equal: a function’s address says nothing.

Tuple Fields

0: fn(&Reader<'_>, &PickedElement) -> Option<Picked>
