Template Function ripple::make_tuple

Function Documentation

template<typename ...Ts>
constexpr auto ripple::make_tuple(Ts&&... values) noexcept -> Tuple<std::decay_t<Ts>...>

This makes a tuple, and is the interface through which tuples should be created in almost all cases.

Example usage is:

auto tuple = make_tuple(4, 3.5, "some value");

This imlementation decays the types, so it will not create refrence types, i.e:

int x = 4, y = 5;
auto tup = make_tuple(x, y);

will copy x and y and not create a tuple of references to the variables. This is done so that in the default case the tuple can be used on both the host and device, and passed to kernels.

int x = 0, y = 0.0f;
Tuple<int&, float&> tuple{x, y};

// Can modify x and y though tuple:
get<0>(tuple) = 4;
get<1>(tuple) = 3.5f;

// Can modify tuple values though x and y:
x = 0; y = 0.0f;

Note

If references are required, then explicit creation of the tuple should be used:

Return

A tuple containing the values.

Parameters

• values: The values to store in the tuple.

Template Parameters

• Ts: The types of the values for the tuple.
