__GNU_PARALLEL::_PLUS(3)

🌸 NAME 🌸

__gnu_parallel::_Plus< _Tp1, _Tp2, _Result > — bestie, it's literally std::plus but it lets you smash two different types together 💖

It lives in the __gnu_parallel namespace and the manual it belongs to is the Library Functions Manual (section 3, iykyk ✨).

---

✨ SYNOPSIS ✨

#include <base.h>

And plot twist: it Inherits std::binary_function< _Arg1, _Arg2, _Result >. So it's got that family tree going on 👑

---

🎀 Public Types 🎀

• typedef _Arg1 first_argument_type — this is the type of the first argument, no cap 🫶
• typedef _Result result_type — this one is the return type, she's the main character of the output 💅
• typedef _Arg2 second_argument_type — and this is the type of the second argument, obviously the sequel 🦋

---

🔥 Public Member Functions 🔥

• _Result operator() (const _Tp1 &__x, const _Tp2 &__y) const — the actual doing-the-thing function, taking __x and __y and handing you back a _Result ⭐

---

🌈 Detailed Description 🌈

Okay so here's the whole vibe, template and all:

template<typename _Tp1, typename _Tp2, typename _Result =
    __typeof__(*static_cast<_Tp1*>(0)              +
    *static_cast<_Tp2*>(0))>
    struct __gnu_parallel::_Plus< _Tp1, _Tp2, _Result >

"Similar to std::plus, but allows two different types." Periodt. 💖

🧚 Little heads-up bestie: that _Result default is doing a whole __typeof__ gymnastics routine on *static_cast<_Tp1*>(0) + *static_cast<_Tp2*>(0) — that's literally how it figures out the result type when you don't tell it. Iconic behaviour, honestly.

💜 Member Typedef Documentation 💜

Three inherited typedefs, all of them coming to you courtesy of std::binary_function< _Arg1, _Arg2, _Result > (yes, [inherited] — she didn't invent these, she just wears them well 🎀).

• template<typename _Arg1, typename _Arg2, typename _Result> typedef _Arg1 std::binary_function< _Arg1, _Arg2, _Result >::first_argument_type [inherited] — first_argument_type is the type of the first argument 💫
• template<typename _Arg1, typename _Arg2, typename _Result> typedef _Result std::binary_function< _Arg1, _Arg2, _Result >::result_type [inherited] — result_type is the return type 👑
• template<typename _Arg1, typename _Arg2, typename _Result> typedef _Arg2 std::binary_function< _Arg1, _Arg2, _Result >::second_argument_type [inherited] — second_argument_type is the type of the second argument 🦋

That's the whole page bestie, we ate and left no crumbs 💅🍓

Signing off with all the love — this doc came out of libstdc++ (that's the source/version, keep it in your notes 📝), and yes, it was brought to you by the Library Functions Manual girlies. Mwah 💖🫶🌸
