std::unordered_set::max_bucket_count

size_type max_bucket_count() const noexcept;
Return maximum number of buckets
Returns the maximum number of buckets that the unordered_set container can have.

This is the maximum potential number of buckets the container can have due to system constraints or limitations on its library implementation.

Parameters

none

Return Value

The maximum number of buckets.

Member type size_type is an unsigned integral type.

// unordered_set limits
#include <iostream>
#include <unordered_set>

int main ()
{
  std::unordered_set<int> myset;

  std::cout << "max_size = " << myset.max_size() << std::endl;
  std::cout << "max_bucket_count = " << myset.max_bucket_count() << std::endl;
  std::cout << "max_load_factor = " << myset.max_load_factor() << std::endl;

  return 0;
}


Possible output:
max_size = 536870911
max_bucket_count = 536870911
max_load_factor = 1

Complexity

Constant.
