With a class which needs to be shared:

struct A;

impl A {
    fn new() -> Self { A }
    fn a(&self) {}
    fn b(&mut self) {}
}

struct AShared(Rc<RefCell<A>>);

is there a way to generate functions which call their inside equivalents? That is, generate some/all of the following:

impl AShared {
    fn new() -> Self { Self(Rc::new(RefCell::new(A::new()))) }
    fn a(&self) { self.0.borrow().a() }
    fn b(&mut self) { self.0.borrow_mut().b() }
}
