  • unordered_dense

    A fast & densely stored hashmap and hashset based on robin-hood backward shift deletion

    • Project mention: unordered_dense: A Fast & Densely Stored Hashmap And Hashset Based On Robin-Hood Backward Shift Deletion | /r/programming | 2023-07-11

  • data-structures

    Go datastructures. (by timtadh)

  • ht.el

    The missing hash table library for Emacs

  • preshed

    💥 Cython hash tables that assume keys are pre-hashed

    • Project mention: Is anyone using PyPy for real work? | news.ycombinator.com | 2023-07-31

    If you have very large dicts, you might find this hash table I wrote for spaCy helpful: https://github.com/explosion/preshed . You need to key the data with 64-bit keys. We use this wrapper around murmurhash for it: https://github.com/explosion/murmurhash

    There's no docs so obviously this might not be for you. But the software does work, and is efficient. It's been executed many many millions of times now.

  • hashtable-bench

    A benchmark for hash tables and hash functions in C++, evaluate on different data as comprehensively as possible
