| error[E0382]: use of moved value: `foo` |
| --> $DIR/as-ref-2.rs:10:14 |
| | |
| LL | let foo = Some(Struct); |
| | --- move occurs because `foo` has type `Option<Struct>`, which does not implement the `Copy` trait |
| LL | let _x: Option<Struct> = foo.map(|s| bar(&s)); |
| | --- ---------------- `foo` moved due to this method call |
| | | |
| | help: consider calling `.as_ref()` or `.as_mut()` to borrow the type's contents |
| LL | let _y = foo; |
| | ^^^ value used here after move |
| | |
| note: `Option::<T>::map` takes ownership of the receiver `self`, which moves `foo` |
| --> $SRC_DIR/core/src/option.rs:LL:COL |
| help: you could `clone` the value and consume it, if the `Struct: Clone` trait bound could be satisfied |
| | |
| LL | let _x: Option<Struct> = foo.clone().map(|s| bar(&s)); |
| | ++++++++ |
| help: consider annotating `Struct` with `#[derive(Clone)]` |
| | |
| LL + #[derive(Clone)] |
| LL | struct Struct; |
