error: `MutexGuard` held across a suspend point, but should not be
--> $DIR/mutex.rs:8:9
|
LL | let _guard = m.lock().unwrap();
| ^^^^^^
LL | other().await;
| ----- the value is held across this suspend point
|
note: holding a MutexGuard across suspend points can cause deadlocks, delays, and cause Futures to not implement `Send`
--> $DIR/mutex.rs:8:9
|
LL | let _guard = m.lock().unwrap();
| ^^^^^^
help: consider using a block (`{ ... }`) to shrink the value's scope, ending before the suspend point
--> $DIR/mutex.rs:8:9
|
LL | let _guard = m.lock().unwrap();
| ^^^^^^
note: the lint level is defined here
--> $DIR/mutex.rs:3:9

LL | #![deny(must_not_suspend)]
| ^^^^^^^^^^^^^^^^
error: aborting due to previous error
