* Package name : parallel-hashmap Version : 1.37 Upstream Author : Copyright: * URL : https://github.com/greg7mdp/parallel-hashmap * License : Apache-2.0 Programming Lang: C Description : <insert up to 60 chars description> 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. Remark: This package is maintained by Debian Science Maintainers at https://salsa.debian.org/science-team/parallel-hashmap
