cuda::zip_function

template<class _Fn>
class zip_function

Adaptor that transforms a functor taking arguments of types Ts… into one accepting a tuple<Ts...>

Template Parameters:

_Fn – The functor to wrap

Public Functions

template<class _Fn2 = _Fn, ::cuda::std::enable_if_t<::cuda::std::default_initializable<_Fn2>, int> = 0>
inline constexpr zip_function(

) noexcept(::cuda::std::is_nothrow_default_constructible_v<_Fn2>)

default construct a zip_function

inline constexpr zip_function(

const _Fn &__fun

) noexcept(::cuda::std::is_nothrow_copy_constructible_v<_Fn>)

construct a zip_function from a functor

inline constexpr zip_function(

_Fn &&__fun

) noexcept(::cuda::std::is_nothrow_move_constructible_v<_Fn>)

construct a zip_function from a functor

template<class _Tuple, ::cuda::std::enable_if_t<(::cuda::std::__can_apply<const _Fn&, _Tuple>), int> = 0>
inline constexpr decltype(auto) operator()(

_Tuple &&__tuple

) const noexcept(__is_nothrow_invocable<const _Fn&, _Tuple>)

Applies a tuple to the stored functor.

Parameters:

__tuple – The tuple of arguments to be passed

template<class _Tuple, ::cuda::std::enable_if_t<(::cuda::std::__can_apply<_Fn&, _Tuple>), int> = 0>
inline constexpr decltype(auto) operator()(

_Tuple &&__tuple

) noexcept(__is_nothrow_invocable<_Fn&, _Tuple>)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
