error: future cannot be sent between threads safely
--> $DIR/unsend-future.rs:20:21
|
LL | require_handler(handler)
| ^^^^^^^ future returned by `handler` is not `Send`
|
= help: within `impl Future<Output = ()>`, the trait `Send` is not implemented for `*const i32`
note: future is not `Send` as this value is used across an await
--> $DIR/unsend-future.rs:15:14
|
LL | let a = &1 as *const i32;
| - has type `*const i32` which is not `Send`
LL | async {}.await;
| ^^^^^ await occurs here, with `a` maybe used later
note: required by a bound in `require_handler`
--> $DIR/unsend-future.rs:11:23
|
LL | fn require_handler<H: Handler>(h: H) {}
| ^^^^^^^ required by this bound in `require_handler`
error: aborting due to 1 previous error
