| error[E0277]: `RefCell<isize>` cannot be shared between threads safely |
| --> $DIR/issue-7364.rs:4:15 |
| | |
| LL | static boxed: Box<RefCell<isize>> = Box::new(RefCell::new(0)); |
| | ^^^^^^^^^^^^^^^^^^^ `RefCell<isize>` cannot be shared between threads safely |
| | |
| = help: the trait `Sync` is not implemented for `RefCell<isize>`, which is required by `Box<RefCell<isize>>: Sync` |
| = note: if you want to do aliasing and mutation between multiple threads, use `std::sync::RwLock` instead |
| = note: required for `Unique<RefCell<isize>>` to implement `Sync` |
| note: required because it appears within the type `Box<RefCell<isize>>` |
| --> $SRC_DIR/alloc/src/boxed.rs:LL:COL |
| = note: shared static variables must have a type that implements `Sync` |

| error[E0015]: cannot call non-const fn `Box::<RefCell<isize>>::new` in statics |
| --> $DIR/issue-7364.rs:4:37 |
| | |
| LL | static boxed: Box<RefCell<isize>> = Box::new(RefCell::new(0)); |
| | ^^^^^^^^^^^^^^^^^^^^^^^^^ |
| | |
| = note: calls in statics are limited to constant functions, tuple structs and tuple variants |
| = note: consider wrapping this expression in `std::sync::LazyLock::new(|| ...)` |
