| error[E0597]: `counter` does not live long enough |
| --> $DIR/issue-54556-niconii.rs:22:20 |

| LL | if let Ok(_) = counter.lock() { } |
| | ^^^^^^^------- |
| | | |
| | 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 `std::result::Result<MutexGuard<'_>, ()>` |
| | |
| = note: The temporary is part of an expression at the end of a block. Consider adding semicolon after the expression so its temporaries are dropped sooner, before the local variables declared by the block are dropped. |
