[ Quellcode: parallel-hashmap  ]

header-only hash map implementation

This repository aims to provide a set of excellent hash map implementations, as well as a btree alternative to std::map and std::set, with the following characteristics:

 * Header only: nothing to build, just copy the parallel_hashmap directory
   to your project and you are good to go.
 * drop-in replacement for std::unordered_map, std::unordered_set,
   std::map and std::set
 * Compiler with C++11 support required, C++14 and C++17 APIs are provided
   (such as try_emplace)
 * Very efficient, significantly faster than your compiler's unordered
   map/set or Boost's, or than sparsepp
 * Memory friendly: low memory usage, although a little higher than
   sparsepp
 * Supports heterogeneous lookup
 * Easy to forward declare: just include phmap_fwd_decl.h in your header
   files to forward declare Parallel Hashmap containers [note: this does
   not work currently for hash maps with pointer keys]
 * Dump/load feature: when a flat hash map stores data that is
   std::trivially_copyable, the table can be dumped to disk and restored
   as a single array, very efficiently, and without requiring any hash
   computation. This is typically about 10 times faster than doing
   element-wise serialization to disk, but it will use 10% to 60% extra
   disk space. See examples/serialize.cc. (flat hash map/set only)
 * Tested on Windows (vs2015 & vs2017, vs2019, Intel compiler 18 and 19),
   linux (g++ 4.8.4, 5, 6, 7, 8, clang++ 3.9, 4.0, 5.0) and MacOS (g++
   and clang++) - click on travis and appveyor icons above for detailed
   test status.
 * Automatic support for boost's hash_value() method for providing the
   hash function (see examples/hash_value.h). Also default hash support
   for std::pair and std::tuple.
