Maybe read a bit on Deref: https://doc.rust-lang.org/std/ops/trait.Deref.html

Any time you have a &String reference, it triggers coercion to &str.

Unfortunately that is not always the case. This fails to compile, for example (and is fairly irritating):

    let my_str = "Hello".to_owned();
    match &my_str {
        "Hello" => (),
        _ => ()
    }

try &*my_str

Yes, that's the trivial "fix" to make it work, but that's not my point. In most other similar situations the compiler does that for me, but not here. It feels like something the compiler should be doing, not me.
