error[E0599]: the method `clone` exists for struct `Box<dyn Foo>`, but its trait bounds were not satisfied
--> $DIR/unique-object-noncopyable.rs:24:16

LL | trait Foo {
| --------- doesn't satisfy `dyn Foo: Clone` or `dyn Foo: Sized`
...
LL | let _z = y.clone();
| ^^^^^ method cannot be called on `Box<dyn Foo>` due to unsatisfied trait bounds

= note: the following trait bounds were not satisfied:
`dyn Foo: Sized`
which is required by `Box<dyn Foo>: Clone`
`dyn Foo: Clone`
which is required by `Box<dyn Foo>: Clone`
= help: items from traits can only be used if the trait is implemented and in scope
= note: the following trait defines an item `clone`, perhaps you need to implement it:
candidate #1: `Clone`
