| LL | assert_is_send(test::<T>()); |
| | ^^^^^^^^^^^ future returned by `test` is not `Send` |
| | |
| = help: within `impl Future<Output = ()>`, the trait `Send` is not implemented for `impl Future<Output = ()>` |
| note: future is not `Send` as it awaits another future which is not `Send` |

| LL | fn assert_is_send(_: impl Send) {} |
