std::hive_limits is a class that holds a layout information about std::hive's block capacity limits.

Data members

Object	Description
min	a value of type std::size_t that represents minimum block capacity limit (public member object)
max	a value of type std::size_t that represents maximum block capacity limit (public member object)

Member functions

std::hive_limits::hive_limits

constexpr hive_limits( std::size_t minimum, std::size_t maximum ) noexcept

(since C++26)

Constructs the hive limits and copy-initializes the data members min and max with provided arguments minimum and maximum accordingly.

Parameters

minimum	-	a value to assign to `this->min`
maximum	-	a value to assign to `this->max`

(class template)

Synopsis

namespace std
{
    struct hive_limits
    {
        size_t min;
        size_t max;

        constexpr hive_limits(size_t minimum, size_t maximum) noexcept
            : min(minimum)
            , max(maximum)
        {}
    };
}

Example

#include <hive>
#include <iostream>

int main()
{
    std::hive h{1, 2, 3};
    std::hive_limits l = h.block_capacity_default_limits();
    std::cout << l.min << ' ' << l.max << '\n';
}
