How to construct a router that only matches on scheme and host?

[tfe]

In thinking about my problem outlined in #102, I had the idea to break it into two routers, where the first only matches on scheme and host and ignores the rest. But I ran into trouble, because when using that to match a whole URL it fails to match due to the presence of the path, query, and any other components of the URL.

It seemed like Rest() might be a good fit, however this seems designed to work with something iterable, which URLRequestData is not ("Generic struct 'Rest' requires that 'URLRequestData' conform to 'Collection'"). I also looked at Skip and a few other ideas but could not find anything that worked.

Example router:

OneOf {
    Route(.case(RootRoute.universalLink)) {
        OneOf {
            Scheme("http")
            Scheme("https")
        }
        Host("www.example.com")
        // What goes here to ignore everything else?
    }

    /// Legacy deep links
    Route(.case(RootRoute.legacyDeepLink)) {
        Scheme("myapp")
        Host("preview")
        // What goes here to ignore everything else?
    }
}
