     = note: `Arc<WGPUAdapterImpl>` is not `Send` and `Sync` as:
     = note: - the trait `Sync` is not implemented for `WGPUAdapterImpl`
     = help: consider using an `Rc` instead. `Arc` does not provide benefits for non `Send` and `Sync` types
     = note: if you intend to use `Arc` with `Send` and `Sync` traits
     = note: wrap the inner type with a `Mutex` or implement `Send` and `Sync` for `WGPUAdapterImpl`
