问题描述

在JavaScript ES6中,有一种称为看起来很相似:

For the specific case of std::tuple (or std::pair) objects, C++ offers the std::tie function which looks similar:

std::tuple<int, bool, double> my_obj {1, false, 2.0};
// later on...
int x;
bool y;
double z;
std::tie(x, y, z) = my_obj;
// or, if we don't want all the contents:
std::tie(std::ignore, y, std::ignore) = my_obj;

我不知道一种符合你的方法。

I am not aware of an approach to the notation exactly as you present it.
