🦋 __gnu_parallel::_DRSSorterPU< _RAIter, _RandomNumberGenerator >(3) 🦋

okay bestie, so this is a page from the Library Functions Manual, and it's all about __gnu_parallel::_DRSSorterPU< _RAIter, _RandomNumberGenerator >. it's a libstdc++ thing, iykyk 💅

✨ NAME ✨

__gnu_parallel::_DRSSorterPU< _RAIter, _RandomNumberGenerator > — literally the local data for one single thread that's out here participating in __gnu_parallel::__parallel_random_shuffle(). that's it. that's the whole vibe. 🫶

🌸 SYNOPSIS 🌸

#include <random_shuffle.h>

🎀 Public Attributes 🎀

  • _BinIndex __bins_end — the end index for the bins this thread is taking care of. bestie has a range and it ends here. ✨
  • _BinIndex _M_bins_begin — the begin index for the bins this thread is taking care of. where the range starts, no cap. 🌸
  • int _M_num_threads — how many threads are participating in total. the whole squad. 👑
  • _DRandomShufflingGlobalData< _RAIter > * _M_sd — a pointer to the global data. yes, global. main character access. 💖
  • uint32_t _M_seed — the random _M_seed for this thread. every thread gets its own lil sparkle of randomness. 🎲

💜 Detailed Description 💜

template<typename _RAIter, typename _RandomNumberGenerator>
    struct __gnu_parallel::_DRSSorterPU< _RAIter, _RandomNumberGenerator >

it's giving "Local data for a thread participating in __gnu_parallel::__parallel_random_shuffle()." that's the description fr fr — each thread gets its own lil personal stash of data so the parallel shuffle can do its thing. 🧚

okay that's the whole page!! this one came from libstdc++, auto-generated by Doxygen straight from the source code, and it's the kind of thing that just exists in the (3) library functions section with no fancy date attached. stay shuffled, bestie 💖🎀🦋
