A C++20 header-only library to convert Structs to Tuples, and Tuples to Structs! Nested structs and tuples are also fully supported!
The functions are fully constexpr so they can be used at both compile- and runtime. A C++20 compiler is required, but changes to make it C++17 friendly should be very simple.
Converting any Struct to a std::tuple is as simple as calling StT::StructToTuple(struct)
struct FooBar
{
int a;
int b;
int c;
};
auto [a, b, c] = StT::StructToTuple(FooBar{});
std::tuple<int, int, int> = StT::StructToTuple(FooBar{});Converting any tuple to a struct is as simple as calling StT::TupleToStruct<Struct>(tuple). Note that the Struct must be given as a template parameter
struct FooBar
{
int a;
int b;
int c;
};
FooBar foo = StT::TupleToStruct<FooBar>(std::tuple<int, int, int>());
