10/// Transparent wrapper for [`Clone`]able types to support all traits (by cloning).

12/// ```rust
13/// # use ownable_core::{AsClone, IntoOwned};
14/// #[derive(Clone)]
15/// struct NotIntoOwned;
16///
17/// fn requires_into_owned<O: IntoOwned>(o: O) {
18///   // do stuff
19/// }
20///
21/// // `AsClone<NotIntoOwned>` implements `IntoOwned` through `Clone`
22/// requires_into_owned(AsClone(NotIntoOwned));
23/// ```
24///
25/// All trait impls work on the inner value as if there is no layer in between
26/// (e.g. `Display` does not add a `AsClone` to the output).
