Description
So rustc is full of these impl_stable_hash_for. What are these for? I originally thought that would be for FxHashMap, but that seems to be wrong (I still need to derive(Hash) to use FxHashMap). So now I am just confused. It would be great if the guide could explain that.
@eddyb said "incremental" but that on its own does not explain much of anything -- why is Hash not good enough? Why do I need a tcx to compute a "stable hash"?
