error[E0597]: `counter` does not live long enough
--> $DIR/issue-54556-niconii.rs:22:20
|
LL | let counter = Mutex;
| ------- binding `counter` declared here
LL |
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 `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
|
LL | if let Ok(_) = counter.lock() { };
