Function std::cell::clone_ref

pub fn clone_ref<T>(orig: &Ref<'b, T>) -> Ref<'b, T> where T: Clone

Deprecated since 1.2.0

: moved to a Ref::clone associated function

Copies a Ref.

The RefCell is already immutably borrowed, so this cannot fail.

A Clone implementation would interfere with the widespread use of r.borrow().clone() to clone the contents of a RefCell.
