A C++ implementation of open addressing hash table algorithms for efficient key-value storage.
hashmap is a C++ library that implements various open addressing hash table algorithms for efficient key-value storage. It provides different collision resolution strategies like linear probing and double hashing, solving the need for high-performance, memory-efficient associative containers in C++ applications.
C++ developers and computer science students who need efficient hash table implementations or want to study open addressing algorithms in practice.
Developers choose hashmap for its clean, focused implementations of fundamental algorithms, making it both a practical library for performance-critical applications and an educational resource for understanding hash table internals.
Various open addressing hashmap algorithms in C++
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements multiple open addressing techniques like linear probing, quadratic probing, and double hashing, providing flexibility in collision resolution strategies for different use cases.
The code is clean and documented, serving as a practical reference for understanding hash table internals, as emphasized in the project description.
Written in modern C++ with a focus on cache efficiency and memory layout, making it suitable for performance-critical applications where speed matters.
Actively maintained with ongoing improvements, ensuring the library evolves with bug fixes and potential algorithm additions.
The README explicitly states that most code is under development, meaning it lacks stability, comprehensive testing, and may have breaking changes.
Focused on core algorithms, so it misses advanced features like custom allocators, robust error handling, or seamless integration with C++ standard library containers.
Relies heavily on the main() function in main.cc for usage examples, with no detailed API documentation or tutorials, making it harder for new users.
