Turn label into structured suggestion for `.as_ref()` and `.as_mut()` ``` 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 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: consider calling `.as_ref()` to borrow the value's contents | LL | let _x: Option<Struct> = foo.as_ref().map(|s| bar(&s)); | +++++++++ help: consider calling `.as_mut()` to mutably borrow the value's contents | LL | let _x: Option<Struct> = foo.as_mut().map(|s| bar(&s)); | +++++++++ ```
