error[E0277]: the trait bound `(): std::future::Future` is not satisfied
--> $DIR/async-error-span.rs:7:20
|
LL | fn get_future() -> impl Future<Output = ()> {
| ^^^^^^^^^^^^^^^^^^^^^^^^ the trait `std::future::Future` is not implemented for `()`
LL |
LL | panic!()
| -------- this returned value is of type `!`
|
= note: the return type of a function must have a statically known size
error[E0698]: type inside `async fn` body must be known in this context
--> $DIR/async-error-span.rs:13:9
|
LL | let a;
| ^ cannot infer type
|
note: the type is part of the `async fn` body because of this `await`
--> $DIR/async-error-span.rs:14:5
|
LL | get_future().await;
| ^^^^^^^^^^^^^^^^^^
error: aborting due to 2 previous errors
