error[E0277]: the trait bound `(): ReturnsSend` is not satisfied
--> $DIR/ice-issue-146191.rs:6:52
|
LL | fn create_complex_future() -> impl Future<Output = impl ReturnsSend> {
| ^^^^^^^^^^^^^^^^ the trait `ReturnsSend` is not implemented for `()`
|
help: this trait has no implementations, consider adding one
--> $DIR/ice-issue-146191.rs:13:1
|
LL | trait ReturnsSend {}
| ^^^^^^^^^^^^^^^^^
note: required by a bound in an opaque type
--> $DIR/ice-issue-146191.rs:6:57
|
LL | fn create_complex_future() -> impl Future<Output = impl ReturnsSend> {
| ^^^^^^^^^^^
error[E0733]: recursion in an async block requires boxing
--> $DIR/ice-issue-146191.rs:8:5
|
LL | async { create_complex_future().await }
| ^^^^^ ----------------------------- recursive call here
|
= note: a recursive `async fn` call must introduce indirection such as `Box::pin` to avoid an infinitely sized future
error: aborting due to 2 previous errors
