A simple one header hashmap implementation for C/C++. Usage Just #include "hashmap.h" in your code! The current supported compilers are gcc, clang and msvc. The current supported platforms are Linux, macOS and Windows. Fundamental Design The hashmap is made to work with any arbitrary data...
Still, due to having various variations of the hash table as HashMap from different libraries, it was decided to use a separate name to call the new implementation to avoid confusion. Therefore, in C++,std::unordered_mapis the alternate name for the HashMap, but another map uses the key-...

LuaHashMap is a hash table library/implementation for use in C. Since C lacks a hash table in the standard library, this library provides a way to fill that hole. But instead of reinventing the wheel again to implement a hash table for C, LuaHashMap cleverly wraps Lua to leverage a pr...
For more information see the examples in test/unit/transparent.cpp.3.2.5. Automatic Fallback to std::hashWhen an implementation for std::hash of a custom type is available, this is automatically used and assumed to be of bad quality (thus std::hash is used, but an additional mixing step...
hashing, where values are stored directly into a memory array, avoiding memory indirections. By using parallel SSE2 instructions, these hashmaps are able to look up items by checking 16 slots in parallel, allowing the implementation to remain fast even when the table is filled up to 87.5% ...
