Matching and derefing non-copy tuples

1

Hello, is there a way to avoid using ref while having that same functionality?

fn works(&(num, ref string): &(i32, String)) {
    todo!()
}

Here num would be i32, but string would be &String.

You can make the bindings outside the parameters:

fn works(tuple: &(i32, String)) {
    let num = tuple.0;
    let string = &tuple.1;
}

But ref is needed if you want it to be in one line.
