std::unorde...bucket_count(3) C++ Standard Libarystd::unorde...bucket_count(3) NAME std::unordered_multiset::max_bucket_count - std::unordered_multi- set::max_bucket_count Synopsis size_type max_bucket_count() const; (since C++11) Returns the maximum number of buckets the container is able to hold due to system or library implementation limitations. Parameters (none) Return value Maximum number of buckets. Complexity Constant. Example // Run this code #include <iostream> #include <unordered_set> int main() { struct Ha { std::size_t operator()(long x) const { return std::hash<long>{}(x); }; }; auto c1 = std::unordered_multiset<char>{}; auto c2 = std::unordered_multiset<long>{}; auto c3 = std::unordered_multiset<long, std::hash<int>>{}; auto c4 = std::unordered_multiset<long, Ha>{}; std::cout << "Max bucket count of\n" << std::hex << std::showbase << "c1: " << c1.max_bucket_count() << '\n' << "c2: " << c2.max_bucket_count() << '\n' << "c3: " << c3.max_bucket_count() << '\n' << "c4: " << c4.max_bucket_count() << '\n' ; } Possible output: Max bucket count of c1: 0xfffffffffffffff c2: 0xfffffffffffffff c3: 0xfffffffffffffff c4: 0xaaaaaaaaaaaaaaa See also bucket_count returns the number of buckets (C++11) (public member function) http://cppreference.com 2022.07.31 std::unorde...bucket_count(3)
