Add str borrowing and fix hash calculation bug

[XX]

@cecton Hashes of the IString::Static("foo") and IString::Rc(Rc::from("foo")) do not match. This is confusing when using an HashMap.

Good catch! Thanks a lot!

May I ask if you are working with Yew?

Looks like clippy might have spotted an interesting issue for once. It's possible that IString::Static("foo") != IString::Rc(Rc::from("foo")). Do you mind also fixing this and adding a test?

I don't know if it's okay for you but if possible I would really like to learn more about your use case for using IMap in a Yew web app (assuming that is what you are doing). Is it an OSS project I can read? Or could you drop a few lines or some code that explains how you use it?

@cecton I fixed it. )

I use Yew in my helper library yew-mdc-widgets of the Rust-and-Yew friendly builders for the Google MDC web components. For example:

let open_menu_button = Button::new()
    .label("Open Menu")
    .on_click(|_| Menu::open_existing("simple-menu"));

let menu = Menu::new().id("simple-menu").items(vec![
    ListItem::new().text("Menu Item 1"),
    ListItem::new().text("Menu Item 2"),
    ListItem::new().text("Menu Item 3"),
]);

html! {
    <div class = { Menu::ANCHOR_CLASS }>
        { open_menu_button }
        { menu }
    </div>
}

Live demo.
Direct link to using IndexMap in the code.

Additionaly, I will be using Yew and yew-mdc-widgets to develop applications for the Local-first web application platform Laplace.

It looks super interesting! Thanks! That might give me some inspiration for https://yewprint.rm.rs/
