STD::TUPLE_ELEMENT(3)

💖 std::tuple_element< __i, _Tp > — Library Functions Manual 💖

okay bestie, so this one lives in the Library Functions Manual section 3, and it's a lil' libstdc++ page about peeking at tuple types. it's short, it's sweet, it's giving ✨template metaprogramming✨. let's go 🦋

---

🌸 NAME 🌸

std::tuple_element< __i, _Tp > — Gives the type of the ith element of a given tuple type.

like, literally that's the whole job. you hand it a tuple type and an index, it hands you back the type of the thing sittin' at that index. no cap 💅

---

✨ SYNOPSIS ✨

template<size_t __i, typename _Tp>
    struct std::tuple_element< __i, _Tp >

that's it. that's the whole vibe. a struct template with two parameters — __i (a size_t, the index) and _Tp (the tuple type you're snooping on) 🎀

---

🫶 Detailed Description 🫶

the main character struct

template<size_t __i, typename _Tp>
    struct std::tuple_element< __i, _Tp >

Gives the type of the ith element of a given tuple type.

that's the description, verbatim, and honestly? it ate. no notes. 💯

so like — the way that this works is you specialize it (or the library does it for you, iykyk) and it just... tells you the type. __i is your index, _Tp is your tuple type, and out pops the type of element number __i. that's the tea 🍓

yep, nobody hand-wrote this one — Doxygen just did its lil' thing and generated the whole page straight from the source. iconic behavior honestly 🙈

---

heads up bestie: this page is auto-generated, so there's no bug list, no options, no exit statuses, no SEE ALSO — it's just the struct declaration and the one-liner description. don't go looking for more, there isn't more 💀

and that's the whole page, periodt 💖 thanks for coming to my ted talk — this was pulled from libstdc++, section 3 of the Library Functions Manual, generated by Doxygen from the source code. mwah, go write some templates 🧚💜
