@Robbepop PTAL

[Robbepop]

@xtqqczze thank you for the ping.

Sorry that I forgot about this. IIRC I didn't merge this right away because I got confused why this needed a rustc-hash dependency change from fxhash. By now it is a little too late to ask and from what I see rustc-hash might even be a better match for the show-case.
