error[E0382]: use of moved value: `foo`
2022-08-16 03:02:04 +00:00
--> $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));
2022-08-16 03:02:04 +00:00
| --- ---------------- `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`
