error: usage of an `Arc` that is not `Send` and `Sync`

|
| ^^^^^^^^^^^^^^^^^^^^^^^^^^

|
|
|
|
= note: `Arc<RefCell<i32>>` is not `Send` and `Sync` as `RefCell<i32>` is not `Sync`
|

= help: if the `Arc` will not used be across threads replace it with an `Rc`
|
|
= help: otherwise make `RefCell<i32>` `Send` and `Sync` or consider a wrapper type such as `Mutex`

= note: `-D clippy::arc-with-non-send-sync` implied by `-D warnings`
|
