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`Ref`.

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

A Clone`Cloneimplementation would interfere with the widespread use ofr.borrow().clone()to clone the contents of aRefCell`.
