如何在 C++11 中将元组转换为字节数组
我需要编写一个函数来将元组转换为字节数组.元组的类型可能包括int、long、double、std::string、char*
等.元组的大小和类型是任意的,比如
I need to write a function to convert tuple to byte array.
The type of tuple may include int, long, double, std::string, char*
,etc.
The size and type of tuple are arbitrary, such as
std:tuple<string, int, double> t1("abc", 1, 1.3);
或
std:tuple<char*, int, int, float, double, string> t2("abc", 1, 2, 1.3, 1.4, "hello");
我想使用这些元组作为输入,字节数组作为返回值.我该怎么办 ?
I want use these tuple as input, and the byte array as return value. What should I do ?
推荐答案
还有精彩的C++ API 用于 消息包,它原生支持元组
There is also the brilliant C++ API for message pack which supports tuples natively
#include <string>
#include <sstream>
#include <tuple>
#include <msgpack.hpp>
int main() {
auto t = std::make_tuple("1", 1, 1.0);
auto buffer = std::stringstream{};
// easy peezy
msgpack::pack(buffer, t);
auto tuple_as_string = buffer.str();
}
