template <typename L>
struct as_pair;Transforms a sequence of two elements into a std::pair.
Use this adapter when you want to adapt your sequence to an std::pair, for example because you are using a function that requires an std::pair as an argument.
#include <brigand/adapted/as_pair.hpp>- L - A sequence of exactly two elements
#include <utility>
#include <brigand/adapted/as_pair.hpp>
#include <brigand/sequences/list.hpp>
using the_list = brigand::list<int, char>;
// any sequence of two elements is accepted by as_pair
using the_pair = brigand::as_pair<the_list>;
// equivalent of writing std::pair<int, char>
the_pair p;
