Suggest `.as_ref()` on borrow error involving `Option`/`Result` When encountering a E0382 borrow error involving an `Option` or `Result` provide a suggestion to use `.as_ref()` on the prior move location to avoid the move. Fix #84165. 2021-04-18 16:37:47 +00:00			`struct Struct;`

			`fn bar(_: &Struct) -> Struct {`
			`Struct`

			`fn main() {`
			`let foo = Some(Struct);`
			`let _x: Option<Struct> = foo.map(\|s\| bar(&s));`
			let _y = foo; //~ERROR use of moved value: `foo`
