| error[E0525]: expected a closure that implements the `Fn` trait, but this closure only implements `FnOnce` |
| --> $DIR/closure-origin-tuple-diagnostics.rs:11:13 |
| | |
| LL | let c = || { |
| | ^^ this closure implements `FnOnce`, not `Fn` |
| LL | let s = s.1; |
| | --- closure is `FnOnce` because it moves the variable `s.1` out of its environment |
| LL | }; |
| LL | expect_fn(c); |
| | --------- the requirement to implement `Fn` derives from here |
