constexpr std::hive_limits block_capacity_limits() const noexcept;		(since C++26)

Returns current block capacity limits, that is, the current-limits.

Return value

An object of type std::hive_limits.

Complexity

Constant.

Example

Run this code

#include <hive>
#include <iostream>

int main()
{
    std::hive<int> colony(100'500);
    const auto limits{colony.block_capacity_limits()};
    std::cout << limits.min << ' ' << limits.max << '\n';
}

Possible output:

76 255
