error[E0277]: `RefCell<()>` cannot be shared between threads safely
  --> $DIR/suggest-ref-cell.rs:8:20

LL |     require_sync::<std::cell::RefCell<()>>();
   |                    ^^^^^^^^^^^^^^^^^^^^^^ `RefCell<()>` cannot be shared between threads safely
   |
   = help: the trait `Sync` is not implemented for `RefCell<()>`
   = note: if you want to do aliasing and mutation between multiple threads, use `std::sync::RwLock` instead
note: required by a bound in `require_sync`
