Function core::cell::clone_ref
[−]
[src]
pub fn clone_ref<'b, T: Clone>(orig: &Ref<'b, T>) -> Ref<'b, T>
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 of
r.borrow().clone()to clone the contents of a
RefCell`.
