💖 NAME 💖

__gnu_parallel::__generic_for_each_selector< _It > — bestie, it's the Generic __selector for embarrassingly parallel functions. That's the whole vibe. ✨

🦋 SYNOPSIS 🦋

Okay so first thing, you gotta bring in the header or nothing works:

#include <for_each_selectors.h>

🎀 Public Attributes 🎀

  • _It _M_finish_iterator — the _Iterator on last element processed; needed for some algorithms (e. g. std::transform()). Yeah she's lowkey the receipts keeper for where you stopped. 🫶

🌸 Inherited by 🌸

Not me showing you the whole friend group — this selector is the blueprint and literally all these icons inherit from her:

  • __gnu_parallel::__accumulate_selector< _It >
  • __gnu_parallel::__adjacent_difference_selector< _It >
  • __gnu_parallel::__count_if_selector< _It, _Diff >
  • __gnu_parallel::__count_selector< _It, _Diff >
  • __gnu_parallel::__fill_selector< _It >
  • __gnu_parallel::__for_each_selector< _It >
  • __gnu_parallel::__generate_selector< _It >
  • __gnu_parallel::__identity_selector< _It >
  • __gnu_parallel::__inner_product_selector< _It, _It2, _Tp >
  • __gnu_parallel::__replace_if_selector< _It, _Op, _Tp >
  • __gnu_parallel::__replace_selector< _It, _Tp >
  • __gnu_parallel::__transform1_selector< _It >
  • __gnu_parallel::__transform2_selector< _It >

✨ Detailed Description ✨

Here's the glow-up moment, the actual declaration:

template<typename _It>
    struct __gnu_parallel::__generic_for_each_selector< _It >

And what is she? She's the "Generic __selector for embarrassingly parallel functions". Main character energy for all the stuff that just splits up and goes brrrr in parallel with zero drama. 👑

🍓 _M_finish_iterator

template<typename _It>
    _It __gnu_parallel::__generic_for_each_selector< _It >::_M_finish_iterator

Repeating her for the people in the back: this is the _Iterator on last element processed; needed for some algorithms (e. g. std::transform()). So like, some algorithms genuinely cannot function without knowing where you finished up. She's not extra, she's essential. 💅

Okay that's the whole page, no notes! 🦋 This one came straight out of libstdc++ — the Library Functions Manual energy, __gnu_para...tor< _It >(3), shipped with the libstdc++ docs. Byeee, go be embarrassingly parallel bestie 💖✨🎀
