cuckoo: Haskell Implementation of Cuckoo Filters
Haskell implementation of Cuckoo filters as described in
Cuckoo filters are a data structure for probabilistic set membership. They support insertion, deletion, and membership queries for set elements.
Membership queries may return false positive results. But queries don't return false negative results.
Unlike Bloom filters, Cuckoo filters maintain an upper bound on the false positive rate that is independent of the load of the filter. However, insertion of new elements in the filter can fail. For typical configurations this probability is very small for load factors smaller than 90 percent.
