--> $DIR/async-error-span.rs:10:20

LL | fn get_future() -> impl Future<Output = ()> {
|
|
| ^^^^^^^^^^^^^^^^^^^^^^^^ `()` is not a future
|
|
|
|
|
= help: the trait `Future` is not implemented for `()`
|
|
= note: () must be a future or must implement `IntoFuture` to be awaited
|

|

error[E0698]: type inside `async fn` body must be known in this context

|
| ^ cannot infer type
|
|

|
|
note: the type is part of the `async fn` body because of this `await`

--> $DIR/async-error-span.rs:19:18
|
|
|
|
|
LL | get_future().await;
