Great work! Can you use xxh3?

This one instead of metrohash.

Will wait for your update. It's great piece of software.

1. By the way, what's the recommended size of NewFilter(1000000) <- what do you suggest? and roughly how much memory is taken by increasing this value?

Sorry I'm a bit dense on this cuckoo filter thing. Can you suggest a value for NewFilter?

I would like to perform matching against 16mil ip addresses.

2. What is a better use case for panmari 16bit cuckoo filter u mentioned? wouldnt everyone want a lower false positive match?

LGTM.

Well, i create a new fork of it.

It uses XXH3 and 16 bits fingerprint(done by panmari)

Maybe someone could try about this?

More "reliable" and faster looking up / inserting.

But i am not sure about that will work well, even though it passed all tests.

However, it still requires testing.
