Struct lens_rs::_box

pub struct _box<Optic>(pub Optic);

build-in optics to create Box, Rc or Arc pointers, implemented Review

assert_eq!(Review::review(optics!(_box), 0), Box::new(0));
assert_eq!(Review::review(optics!(_box), 0), Rc::new(0));
assert_eq!(Review::review(optics!(_box), 0), Arc::new(0));

or to visit the data in Box, implemented Lens

assert_eq!(Box::new(0).view(optic!(_box)), 0);
