__GNU_PARALLEL::__IDENTITY_SELECTOR(3cxx)

💖 NAME 💖

__gnu_parallel::__identity_selector< _It > is the main character of this 3cxx manual page, bestie. Its whole personality is: Selector that just returns the passed iterator. No cap, that's the tea. 🫶

✨ SYNOPSIS ✨

Okay so first you gotta bring in the header:

#include <for_each_selectors.h>

It inherits from __gnu_parallel::__generic_for_each_selector< _It > — family tree, slay. 🌳

🌸 Public Member Functions 🌸

• template<typename _Op > _It operator() (_Op __o, _It __i) — Functor execution. That's the one job, and it ate. 💅

🎀 Public Attributes 🎀

• _It _M_finish_iterator — _Iterator on last element processed; needed for some algorithms (e. g. std::transform()). Lowkey important for those transform girlies. ✨

🦋 Detailed Description 🦋

Here's the struct line exactly, weird little quote mark and all — not me touching it, I promise:

template<typename _It>
    struct __gnu_parallel::__identity_selector< _It >"Selector that just
    returns the passed iterator.

The vibe check: it returns the iterator you passed in. That's it. That's the selector. Iconic minimalism. 🎀

💅 Member Function Documentation 💅

🔥 operator() 🔥

template<typename _It > template<typename _Op > _It
    __gnu_parallel::__identity_selector< _It >::operator() (_Op __o, _It
    __i) [inline]

Functor execution. Periodt. It's inline, it's cute, it's doing the functor thing. 💅

🌸 Parameters 🌸

• __o — Operator (unused). Not me ignoring him, he's literally marked unused. 🙈
• __i — iterator referencing object. This is the one that matters, bestie. 🎯

✨ Returns ✨

Passed iterator. It gives you back exactly what you handed it. No plot twist. 🦋

🌈 _M_finish_iterator 🌈

template<typename _It > _It __gnu_parallel::__generic_for_each_selector< _It
    >::_M_finish_iterator [inherited]

_Iterator on last element processed; needed for some algorithms (e. g. std::transform()). Yes bestie, it's inherited — it comes from the generic selector side of the family. 👑

Okay cute sign-off: the footer source/version string is libst__gnu_parallel:...selector< _It >(3cxx). There's no date shown in the page I was handed, so I'm not inventing one — fr fr, no cap. Bye bestie, go return that iterator. 💖🦋✨
