error: future cannot be sent between threads safely
--> $DIR/issue-67252-unnamed-future.rs:21:11
|
LL | spawn(async {
| ___________^
LL | | let a = std::ptr::null_mut::<()>(); // `*mut ()` is not `Send`
LL | | AFuture.await;
LL | | drop(a);
LL | | });
| |_____^ future created by async block is not `Send`
|
= help: within `[async block@$DIR/issue-67252-unnamed-future.rs:21:11: 25:6]`, the trait `Send` is not implemented for `*mut ()`
note: future is not `Send` as this value is used across an await
--> $DIR/issue-67252-unnamed-future.rs:23:16
|
LL | let a = std::ptr::null_mut::<()>(); // `*mut ()` is not `Send`
| - has type `*mut ()` which is not `Send`
LL | AFuture.await;
| ^^^^^^ await occurs here, with `a` maybe used later
LL | drop(a);
LL | });
| - `a` is later dropped here
note: required by a bound in `spawn`
--> $DIR/issue-67252-unnamed-future.rs:9:13
|
LL | fn spawn<T: Send>(_: T) {}
| ^^^^ required by this bound in `spawn`
error: aborting due to previous error
