| error: captured variable cannot escape `FnMut` closure body |

| LL | let mut vec: Vec<i32> = Vec::new(); |
| | ------- variable defined here |
| LL | let closure = move || { |
| | - inferred to be a `FnMut` closure |
| LL | vec.clear(); |
| | --- variable captured here |
| LL | let mut iter = vec.iter(); |
| LL | move || { iter.next() } |
| | ^^^^^^^^^^^^^^^^^^^^^^^ returns a closure that contains a reference to a captured variable, which then escapes the closure body |
| | |
| = note: `FnMut` closures only have access to their captured variables while they are executing... |
| = note: ...therefore, they cannot allow references to captured variables to escape |
