+error[E0277]: `RefCell<isize>` cannot be shared between threads safely

+   |               ^^^^^^^^^^^^^^^^^^^ `RefCell<isize>` cannot be shared between threads safely
+   |
+   = help: the trait `Sync` is not implemented for `RefCell<isize>`
+   = note: required because of the requirements on the impl of `Sync` for `Unique<RefCell<isize>>`
+   = note: required because it appears within the type `Box<RefCell<isize>>`
+   = note: shared static variables must have a type that implements `Sync`

+error: aborting due to previous error
