__gnu_pbds::ran...ation_guarantee(3cxx)

💅 __gnu_pbds::range_invalidation_guarantee

ok so bestie, welcome to the libstdc++ manual, section 3cxx — this page is all about one very specific little trait struct, and honestly? it's giving "niche but iconic". 🎀

---

✨ NAME ✨

__gnu_pbds::range_invalidation_guarantee — the trait that says "your iterators stay put, even when the container gets a whole makeover" 💫

---

🦋 SYNOPSIS 🦋

#include <tag_and_trait.hpp>

Inherits __gnu_pbds::point_invalidation_guarantee.

---

🌸 Detailed Description 🌸

Okay so here's the tea ☕ — this thing signifies an invalidation guarantee that includes all the guarantees of its base class, and then some. Specifically, it promises that any range-type iterator (and yes, that includes whatever begin() and end() hand back to you, bestie) stays in the correct relative positions to other range-type iterators — as long as its corresponding entry hasn't been erased. And that holds regardless of modifications to the container object. no cap. 🔥

literally the main character of iterator stability — modified container? doesn't matter. erased entry? okay yeah, then it's over 💀
