💖 __gnu_pbds::detail::maybe_null_type< Key, Mapped, _Alloc, Store_Hash > 💖

okay bestie, welcome to the manual page for __gnu_pbds::detail::maybe_null_type< Key, Mapped, _Alloc, Store_Hash > from the __gnu_pbds...ore_Hash >(3) corner of the library, and I promise it's less scary than it looks 🫶

✨ NAME ✨

__gnu_pbds::detail::maybe_null_type< Key, Mapped, _Alloc, Store_Hash > — it's the base class for conditionally defining a static data member. that's it, that's the whole vibe 💅

🌸 SYNOPSIS 🌸

#include <types_traits.hpp>

Inherited by __gnu_pbds::detail::types_traits< Key, Mapped, _Alloc, false >, __gnu_pbds::detail::types_traits< Key, Data, _Alloc, false >, __gnu_pbds::detail::value_type< Key, Mapped, _Alloc, false >, and __gnu_pbds::detail::types_traits< Key, Mapped, _Alloc, Store_Hash >. no cap, those four are literally in the family tree 👑

🦋 Detailed Description 🦋

template<typename Key, typename Mapped, typename _Alloc, bool Store_Hash>
struct __gnu_pbds::detail::maybe_null_type< Key, Mapped, _Alloc, Store_Hash >

and what does it do? say it with me: "Base class for conditionally defining a static data member." iconic. periodt. 💜

🎀 Author 🎀

Generated automatically by Doxygen for libstdc++ from the source code. not a human, just a little robot doing its best 🙈

lowkey the whole point is: this is an internal detail helper, so pls don't go building your whole personality around it, but now you know it and that's what matters 💖

that's the page, bestie — this was libstdc++, from the __gnu_pbds...ore_Hash >(3) manual, and it was generated automatically by Doxygen for libstdc++ from the source code ✨ mwah, go slay some templates 🫶
