error: future cannot be shared between threads safely
--> $DIR/issue-64130-1-sync.rs:21:13
|
LL | is_sync(bar());
| ^^^^^ future returned by `bar` is not `Sync`
|
= help: within `impl Future<Output = ()>`, the trait `Sync` is not implemented for `Foo`
note: future is not `Sync` as this value is used across an await
--> $DIR/issue-64130-1-sync.rs:15:10
|
LL | let x = Foo;
| - has type `Foo` which is not `Sync`
LL | baz().await;
| ^^^^^^ await occurs here, with `x` maybe used later
LL | }
| - `x` is later dropped here
note: required by a bound in `is_sync`
--> $DIR/issue-64130-1-sync.rs:11:15

LL | fn is_sync<T: Sync>(t: T) { }
| ^^^^ required by this bound in `is_sync`
error: aborting due to previous error
