std::flat_m...p::max_size(3) C++ Standard Libary std::flat_m...p::max_size(3) NAME std::flat_multimap::max_size - std::flat_multimap::max_size Synopsis size_type max_size() const noexcept; (since C++23) Returns the maximum number of elements the container is able to hold due to system or library implementation limitations. Equivalent to std::min<size_type>(c.keys.max_size(), c.values.max_size()). Parameters (none) Return value Maximum number of elements. Complexity Constant. Notes This value typically reflects the theoretical limit on the size of the container, at most std::numeric_limits<difference_type>::max(). At runtime, the size of the container may be limited to a value smaller than max_size() by the amount of RAM available. Example // Run this code #include <iostream> #include <flat_map> #include <locale> int main() { std::flat_multimap<char, char> q; std::cout.imbue(std::locale("en_US.UTF-8")); std::cout << "Maximum size of a std::flat_multimap is " << q.max_size() << '\n'; } Possible output: Maximum size of a std::flat_multimap is 768,614,336,404,564,650 See also size returns the number of elements (public member function) http://cppreference.com 2024.06.10 std::flat_m...p::max_size(3)
