SipHasher::new_with_keys(0,0) is just a longer version of just _::new()
i.e. the latter is an alias for the former.

Just a bit of a nothing burger I noticed while debugging some other issue.

Hmmm, is that guaranteed to be stable for ::new()?

Thanks for the PR! And yeah I think the original reason I did this was to guarantee that the same keys were used each time, although if SipHasher::new is documented as using two zero keys then I think it's fine to run with that and assume it won't change.

Wanna un-flag as a work-in-progress and I can r+?

Yeap, thanks for the review. TIL about Sip Hasher!

Edit: To your point, I would argue using the same interface is better, because then any changes will be reflected in all of them.
