std::flat_multiset<Key,Compare,KeyContainer>::max_size
From cppreference.com
< cpp | container | flat multiset
| 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, i.e. std::distance(begin(), end()) for the largest container.
Contents |
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_set> #include <locale> int main() { std::flat_multiset<char> q; std::cout.imbue(std::locale("en_US.UTF-8")); std::cout << "Maximum size of a std::flat_multiset is " << q.max_size() << '\n'; }
Possible output:
Maximum size of a std::flat_multiset is 768,614,336,404,564,650
