error[E0106]: missing lifetime specifier

5 |         fn borrowed() -> UniquePtr<Borrowed>;
  |                                    ^^^^^^^^ expected named lifetime parameter
  |
  = help: this function's return type contains a borrowed value, but there is no value for it to be borrowed from
help: consider using the `'static` lifetime

5 |         fn borrowed() -> UniquePtr<Borrowed<'static>>;
