hashset

A javascript standard data structure library which benchmark against C++ STL.

Fast, low-allocation ports of List, Dictionary, HashSet, Stack, and Queue using ArrayPool and Span.

The Capsule Hash Trie Collections Library

Excalibur Hash is a high-speed hash map and hash set, ideal for performance-critical uses like video games

The go-set package provides generic Set implementations for Go, including HashSet for types with a Hash() function and TreeSet for orderable data

Xor filters - efficient probabilistic hashsets. Faster and smaller than bloom and cuckoo filters.

Library providing fast hash based immutable map and set

A TwinCAT library for creating and manipulating dynamic collections of data in TwinCAT. It provides multiple data structures such as ArrayList (a dynamic array), List (a doubly linked list that is optimized for sequential access and mutation), Set, Map, Queue, Stack and more. Examples are in the project.
