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>`
= 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 associated function `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(|| ...)`
error: aborting due to 2 previous errors
