Functions

template<typename F, typename Tuple> constexpr detail::invoke_fused_result<F, Tuple>::type invoke_fused(F &&f, Tuple &&t) noexcept(noexcept(detail::invoke_fused_impl(detail::fused_index_pack_t<Tuple>{}, HPX_FORWARD(F, f), HPX_FORWARD(Tuple, t))))#

Invokes the given callable object f with the content of the sequenced type t (tuples, pairs)

Note

This function is similar to std::apply (C++17)

Parameters

f – Must be a callable object. If f is a member function pointer, the first argument in the sequenced type will be treated as the callee (this object).
t – A type whose contents are accessible through a call to hpx::get.

Throws

std::exception – like objects thrown by call to object f with the arguments contained in the sequenceable type t.

Returns

The result of the callable object when it’s called with the content of the given sequenced type.

template<typename R, typename F, typename Tuple> constexpr R invoke_fused_r(F &&f, Tuple &&t) noexcept(noexcept(detail::invoke_fused_impl(detail::fused_index_pack_t<Tuple>{}, HPX_FORWARD(F, f), HPX_FORWARD(Tuple, t))))#

Template Parameters: R – The result type of the function when it’s called with the content of the given sequenced type.
