如何将boost::asio::ip::address_v6 IP转换为2个uint64_t编号，然后再从2个uint64_t转换为v6地址？

#include <boost/asio/ip/address_v6.hpp>
#include <iostream>

void convertIPv6ToUint64(const boost::asio::ip::address_v6& ipv6, uint64_t& part1, uint64_t& part2) {
    const auto& addr = ipv6.to_bytes();
    part1 = (static_cast<uint64_t>(addr[0]) << 48) | (static_cast<uint64_t>(addr[1]) << 32) |
            (static_cast<uint64_t>(addr[2]) << 16) | static_cast<uint64_t>(addr[3]);
    part2 = (static_cast<uint64_t>(addr[4]) << 48) | (static_cast<uint64_t>(addr[5]) << 32) |
            (static_cast<uint64_t>(addr[6]) << 16) | static_cast<uint64_t>(addr[7]);
}

void convertUint64ToIPv6(uint64_t part1, uint64_t part2, boost::asio::ip::address_v6& ipv6) {
    boost::asio::ip::address_v6::bytes_type addr;
    addr[0] = static_cast<uint8_t>((part1 >> 48) & 0xFF);
    addr[1] = static_cast<uint8_t>((part1 >> 32) & 0xFF);
    addr[2] = static_cast<uint8_t>((part1 >> 16) & 0xFF);
    addr[3] = static_cast<uint8_t>(part1 & 0xFF);
    addr[4] = static_cast<uint8_t>((part2 >> 48) & 0xFF);
    addr[5] = static_cast<uint8_t>((part2 >> 32) & 0xFF);
    addr[6] = static_cast<uint8_t>((part2 >> 16) & 0xFF);
    addr[7] = static_cast<uint8_t>(part2 & 0xFF);
    ipv6 = boost::asio::ip::address_v6(addr);
}

int main() {
    boost::asio::ip::address_v6 ipv6 = boost::asio::ip::address_v6::from_string("2001:db8::1");
    uint64_t part1, part2;
    convertIPv6ToUint64(ipv6, part1, part2);
    std::cout << "Part 1: " << part1 << std::endl;
    std::cout << "Part 2: " << part2 << std::endl;

    boost::asio::ip::address_v6 convertedIPv6;
    convertUint64ToIPv6(part1, part2, convertedIPv6);
    std::cout << "Converted IPv6: " << convertedIPv6.to_string() << std::endl;

    return 0;
}
