subview member function ?

[kyungjoo-kim]

Now we have dynrankview and view and they have different subview syntax. If I receive a view with a template type, for instance

template<typeanme ViewType>
void function(ViewType a) {
  // either of two are needed
  auto sub = Kokkos::subview(a, 1, Kokkos::ALL());
  auto sub = Kokkos::subdynrankview(a, 1, Kokkos::ALL());

  // is this possible or other unified wayt to create a subview ? 
  auto sub = a::subview(a, 1, Kokkos::ALL());
  auto sub = decltype(a)::subview(a, 1, Kokkos::ALL());
}

If I understand correctly, the template type ViewType may be either DynRankView of View, so you are wanting a generic subview call that works for both.
Currently what you have (auto sub = a::subview(...) ) is not possible, the name change to subdynview was made due to some implicit conversions causing the compiler trouble deducing the proper subview. I can look back into that.

Yes.You got the point. If we have a generic subview, that would be the best. Alternatively my suggestion is to put static member function of subview under the view so that proper subview is derived from the view.

Need to resolve the 'subview' vs. 'subdynrankview' function resolution issue as opposed to adding a member function.

@kyungjoo-kim
With #359 can now use subview function with DynRankView
