About

Family of header-only, fast, memory-friendly C++ hashmap and btree containers

parallel-hashmap

Include the library in a C++ project for high-performance hash maps

$ #include <parallel_hashmap/phmap.h>
phmap::flat_hash_map<std::string, int> map;

Use btree container for ordered key-value storage with better cache locality

$ #include <parallel_hashmap/btree.h>
phmap::btree_map<int, std::string> btree;

Compile a program using parallel-hashmap headers$ clang++ -I/usr/local/include -std=c++17 myprogram.cpp -o myprogram
