= 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

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`
