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 `Lazy::new(|| ...)` from the `once_cell` crate: https://crates.io/crates/once_cell
