error[E0597]: `counter` does not live long enough

|
| borrowed value does not live long enough
|
|
| a temporary with access to the borrow is created here ...

|

|
|
| `counter` dropped here while still borrowed
|
|
| ... and the borrow might be used here, when that temporary is dropped and runs the destructor for type `Result<MutexGuard<'_>, ()>`
|
|
|
|
|
help: consider adding semicolon after the expression so its temporaries are dropped sooner, before the local variables declared by the block are dropped
