| 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 ... |

| LL | } |
| | - |
| | | |
| | `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 |
