template<typename T , require_t< std::is_rvalue_reference< T && > > * = nullptr, std::enable_if_t< static_cast< bool >(Eigen::internal::traits< std::decay_t< T > >::Flags &Eigen::NestByRefBit)> * = nullptr>

auto stan::math::internal::holder_handle_element ( T &&  a, T *&  res  )

inline

Handles single element (moving rvalue non-expressions to heap) for construction of holder or holder_cl from a functor.

Rvalue non-expression is moved to heap and the pointer to heap memory is assigned to res and returned in a tuple.

Template Parameters

T	type of the element

Parameters

a	element to handle
res	resulting pointer to element

Returns

tuple of pointers allocated on heap (containing single pointer).
