pub struct ARef<'a, T: ?Sized + 'a> { /* fields omitted */ }
Expand description
A Ref
that might not actually be borrowed.
Either a Ptr
(a normal & style reference), or a Ref
(like from
RefCell
), but exposes all the methods available on Ref
.
Create a new ARef
from a pointer.
Create a new ARef
from a reference.
See Ref.clone
. Not a self method since that interferes with the Deref
.
