| LL | is_send(foo()); |
| | ^^^^^ future returned by `foo` is not `Send` |
| | |
| = help: within `impl Future<Output = ()>`, the trait `Send` is not implemented for `MutexGuard<'_, u32>`, which is required by `impl Future<Output = ()>: Send` |
| note: future is not `Send` as this value is used across an await |

| LL | let g = x.lock().unwrap(); |
| | - has type `MutexGuard<'_, u32>` which is not `Send` |
| LL | baz().await; |
| | ^^^^^ await occurs here, with `g` maybe used later |
| note: required by a bound in `is_send` |
