__GNU_DEBUG::_SAFE_VECTOR(3)

💖 NAME 💖

okay bestie, say hi to __gnu_debug::_Safe_vector< _SafeSequence, _BaseSequence > — she's the base class for Debug Mode vector ✨. Like, the momager of debug-mode vectors. She's in the Library Functions Manual, she's iconic, she's lowkey doing the most behind the scenes 💅

---

🎀 SYNOPSIS 🎀

first things first, you gotta pull her in:

#include <vector>

and she's inherited by... wait no, std::__debug::vector< _Tp, _Allocator >. That's the nepo baby. Adorable. We support her 🫶

✨ Protected Member Functions ✨

these are the family-only functions, no randos allowed:

• constexpr _Safe_vector (_Safe_vector &&__x) noexcept — move-constructs her, and she will not throw at you, periodt
• constexpr _Safe_vector (const _Safe_vector &) noexcept — copy-constructs her, also noexcept, she's unbothered fr fr
• constexpr _Safe_vector (size_type __n) noexcept — builds her with a size of __n, again noexcept, she simply does not have the range for exceptions
• bool _M_requires_reallocation (size_type __elements) const noexcept — asks the question: do we need to reallocate for __elements? returns a bool, const, noexcept, a whole vibe check 🦋
• constexpr void _M_update_guaranteed_capacity () noexcept — refreshes the guaranteed capacity info, returns void because she gives, not takes 💜
• constexpr _Safe_vector & operator= (_Safe_vector &&__x) noexcept — move-assign, hands back a reference to herself, noexcept
• constexpr _Safe_vector & operator= (const _Safe_vector &) noexcept — copy-assign, also hands back _Safe_vector &, also noexcept

🌸 Protected Attributes 🌸

• size_type _M_guaranteed_capacity — her little diary entry 📓 tracking the guaranteed capacity. main character data, honestly

👑 Detailed Description 👑

template<typename _SafeSequence, typename _BaseSequence>
class __gnu_debug::_Safe_vector< _SafeSequence, _BaseSequence >

so what does she even do, bestie? she's the base class for Debug Mode vector 💀 no cap.

and then — the plot twist — she adds information about the guaranteed capacity. Which is genuinely so useful, because it's how you catch code that's out here relying on non-portable implementation details of the libstdc++ reallocation policy 😭 like girl, that's not portable, that's not it, put it down 🙈

🧚 Author 🧚

she was generated automatically by Doxygen for libstdc++ from the source code. not a human author, just a robot doing her lil thing 🤖✨

okay that's the whole page, mwah 💋 shoutout to libstdc++ for this one, generated straight from the source code — love that for us 🫶🌈⭐
