error: captured variable cannot escape `FnMut` closure body
|
|
--> $DIR/do-not-suggest-adding-move-when-closure-is-already-marked-as-move.rs:6:9
|
|
|
|
|
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
