__GNU_PBDS::CC_HASH_MAX_COLLISION_CHECK_RESIZE_TRIGGER(3)
π NAME π
__gnu_pbds::cc_hash_max_collision_check_resize_trigger< External_Load_Access, Size_Type > β bestie, this is a resize trigger policy based on collision checks, and the way it works is it keeps the simulated load factor lower than some given load factor. That's it, that's the girl. β¨

β¨ Detailed Description β¨
template<bool External_Load_Access = false, typename Size_Type = std::size_t>
class __gnu_pbds::cc_hash_max_collision_check_resize_trigger< External_Load_Access, Size_Type >
"A resize trigger policy based on collision checks. It keeps the simulated load factor lower than some given load factor."
Periodt. π That's the whole personality: watch the collisions, keep the simulated load factor under the load factor you told it about. Lowkey elegant, honestly.
π Member Enumeration Documentation π
template<bool External_Load_Access = false, typename Size_Type = std::size_t>
anonymous enum
Enumerator:
external_load_accessβ specifies whether the load factor can be accessed externally. The two options have different trade-offs in terms of flexibility, genericity, and encapsulation. iykyk π§

ok so that's the whole page, no gatekeeping π every lastnotify_*is in there, every[inline], every[protected], theReferences notify_resized()and theReferenced by notify_cleared()cross-links, the template defaults, all of it. Nothing dropped, nothing invented.
And that's a wrap, bestie β this whole thing was auto-generated by Doxygen for libstdc++ from the source code, and it's the __gnu_pbds...Size_Type >(3) page from the Library Functions Manual. Take care of her, she's doing her best with all those collisions. πππ¦
