| error[E0507]: cannot move out of `self.b`, as `self` is a captured variable in an `Fn` closure |

| | |
| LL | async fn foo(&self) { |
| | ----- |
| | | |
| | captured outer variable |
| | move occurs because `self.b` has type `StructB`, which does not implement the `Copy` trait |
| LL | let bar = self.b.bar().await; |

| | ------- captured by this `Fn` closure |
| LL | |
| LL | self.b; |
| | ^^^^^^ `self.b` is moved here |
| | |
| help: `Fn` and `FnMut` closures require captured values to be able to be consumed multiple times, but `FnOnce` closures may consume them only once |

| LL | async fn spawn_blocking<T>(f: impl (Fn() -> T) + Send + Sync + 'static) -> T { |
| | ^^^^^^^^^^^ |
| note: if `StructB` implemented `Clone`, you could clone the value |

| LL | struct StructB {} |

| | `self` is a reference that is only valid in the method body |

| | | ^ |
| | | | |
| | |__________`self` escapes the method body here |
| | argument requires that `'1` must outlive `'static` |
