Structured bindings were introduced in c++17 as an easier way of getting data out of std::pair, std::tuple and the map containers. They are also quite handy to extract data from simple data aggregates, here is an example using the ubiquitous x,y Point struct

#include <iostream>
#include <type_traits>

struct Point
{
    int x = 1;
    int y = 1;
};

int main()
{
    Point point;
    auto [x, y] = point;
    std::cout << std::boolalpha << std::is_same_v<int, decltype(x)>;
}
