error: future cannot be sent between threads safely
--> $DIR/missing-send-bound.rs:13:20
|
LL | assert_is_send(test::<T>());
| ^^^^^^^^^^^ future returned by `test` is not `Send`
|
= help: within `impl Future<Output = ()>`, the trait `Send` is not implemented for `impl Future<Output = ()>`
note: future is not `Send` as it awaits another future which is not `Send`
--> $DIR/missing-send-bound.rs:9:5
|
LL | T::bar().await;
| ^^^^^^^^ await occurs here on type `impl Future<Output = ()>`, which is not `Send`
note: required by a bound in `assert_is_send`
--> $DIR/missing-send-bound.rs:17:27
|
LL | fn assert_is_send(_: impl Send) {}
| ^^^^ required by this bound in `assert_is_send`
help: `Send` can be made part of the associated future's guarantees for all implementations of `Foo::bar`
|
LL - async fn bar();
LL + fn bar() -> impl std::future::Future<Output = ()> + Send;
|
error: aborting due to 1 previous error
