std::type_index(3)

💖 std::type_index — the manual page, but make it make sense 💖

okay bestie, welcome to std::type_index(3) from the Library Functions Manual, and yes we're doing this together because you deserve to actually get it 🫶

---

✨ NAME ✨

std::type_index — it's a class. that's the whole name. iconic behaviour honestly 👑

---

🌸 SYNOPSIS 🌸

first things first, you gotta invite it to the party:

#include <typeindex>

🎀 Public Member Functions 🎀

here's the whole roster, no one's getting left out:

type_index (const type_info &__rhs) noexcept
size_t hash_code () const noexcept
const char * name () const noexcept
bool operator!= (const type_index &__rhs) const noexcept
bool operator< (const type_index &__rhs) const noexcept
bool operator<= (const type_index &__rhs) const noexcept
bool operator== (const type_index &__rhs) const noexcept
bool operator> (const type_index &__rhs) const noexcept
bool operator>= (const type_index &__rhs) const noexcept

notice how every single one of them is noexcept? the way that this class simply refuses to throw is giving emotional stability 💅 she does not do drama, she does not do exceptions, she just vibes ✨

🦋 Detailed Description 🦋

so, Class type_index.

here's the tea: type_index is a cute little wrapper around type_info. that's it, that's the job. she's a glow-up for type_info so you can actually use her as an index type — specifically in associative containers (23.6) and in unordered associative containers (23.7) 🌈

like, type_info alone couldn't sit in those containers, and type_index said "not on my watch" and stepped in. main character energy fr fr 🔥
