std::ranges::sized_range(3cxx)

✨ std::ranges::sized_range ✨

okay so bestie, welcome to the 3cxx manual page for std::ranges::sized_range 💖 this is the libstdc++ corner of the C++ docs, so you know it's giving ✨standard library realness✨.

---

🌸 NAME 🌸

std::ranges::sized_range — [range.sized] the sized_range concept, and yes she's a concept, not a class, not a vibe, a concept 💅

---

🎀 SYNOPSIS 🎀

First things first, you gotta bring her in:

#include <ranges>

Then, the concept definition itself, no cap:

template<typename _Tp>
concept std::ranges::sized_range =  range<_Tp>
      && requires(_Tp& __t) { ranges::size(__t); }

look at her 🦋 she's literally just a range<_Tp> that also has to survive a requires clause calling ranges::size(__t) on a _Tp& — if that expression checks out, she's in her main character era, if not, she's not a sized_range, periodt.

💜 Detailed Description 💜

[range.sized] the sized_range concept. 🌈 that's the whole thing bestie, that's the section. short, sweet, iconic, ate. 👑

lowkey the [range.sized] tag is the citation for where this lives in the standard, so if anyone asks, iykyk 🫶
