error[E0277]: `impl Future<Output = ()>` cannot be sent between threads safely
--> $DIR/send-on-foreign-async-fn-in-trait.rs:9:16

LL | needs_send(T::test());
| ---------- ^^^^^^^^^ `impl Future<Output = ()>` cannot be sent between threads safely

| required by a bound introduced by this call

= help: the trait `Send` is not implemented for `impl Future<Output = ()>`
note: `<T as Foo>::test` is an `async fn` in trait, which does not automatically imply that its future is `Send`
--> $DIR/auxiliary/foreign-async-fn.rs:4:5

LL | async fn test();

note: required by a bound in `needs_send`
