std::flat_set<Key,Compare,KeyContainer>::max_size
From cppreference.com
size_type max_size()constnoexcept; | (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.

[edit]Parameters
(none)
[edit]Return value
Maximum number of elements.
[edit]Complexity
Constant.
[edit]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.
[edit]Example
Run this code
#include <iostream>#include <flat_set>#include <locale> int main(){std::flat_set<char> q;std::cout.imbue(std::locale("en_US.UTF-8"));std::cout<<"Maximum size of a std::flat_set is "<< q.max_size()<<'\n';}
Possible output:
Maximum size of a std::flat_set is 768,614,336,404,564,650
