error[E0525]: expected a closure that implements the `Fn` trait, but this closure only implements `FnMut`
--> $DIR/issue-34349.rs:26:17
|
LL | let diary = || { //~ ERROR E0525
| ^^ this closure implements `FnMut`, not `Fn`
LL | farewell.push_str("!!!");
| -------- closure is `FnMut` because it mutates the variable `farewell` here
...
LL | apply(diary);
| ----- the requirement to implement `Fn` derives from here
error: aborting due to previous error
