error: future cannot be sent between threads safely

|
--> $DIR/unsend-future.rs:19:21
|
|
|
|
|
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:15:13
|
|
|
|
|
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
|
|
LL | }
|
|
| - `a` is later dropped here
|
|
note: required by a bound in `require_handler`
