error[E0507]: cannot move out of `y`, a captured variable in an `Fn` closure
|
|
--> $DIR/unboxed-closures-move-upvar-from-non-once-ref-closure.rs:12:9
|
|
|
|
|
LL | let y = vec![format!("World")];
|
|
| - captured outer variable
|
|
LL | call(|| {
|
|
| -- captured by this `Fn` closure
|
|
LL | y.into_iter();
|
|
| ^ ----------- `y` moved due to this method call
|
|
| |
|
|
| move occurs because `y` has type `Vec<String>`, which does not implement the `Copy` trait
|
|
|
|
|
note: `into_iter` takes ownership of the receiver `self`, which moves `y`
|
|
--> $SRC_DIR/core/src/iter/traits/collect.rs:LL:COL
|
|
help: you can `clone` the value and consume it, but this might not be your desired behavior
|
|
|
|
|
LL | <Vec<String> as Clone>::clone(&y).into_iter();
|
|
| +++++++++++++++++++++++++++++++ +
|
|
help: consider cloning the value if the performance cost is acceptable
|
|
|
|
|
LL | y.clone().into_iter();
