extents()

template<concepts::View ViewType>

KOKKOS_FUNCTION constexpr auto Kokkos::utils::view::extents ( const ViewType & view )

constexpr

Get all extents of view.

Definition at line 34 of file extents.hpp.

slice() [1/2]

template<size_t Rank, typename ViewType, typename... Indices>
requires concepts::ViewOfRank<std::remove_reference_t<ViewType>, Rank>

KOKKOS_FUNCTION constexpr auto Kokkos::utils::view::slice ( ViewType && view, Indices &&... indices )

constexpr

Get a subview, given the first indices. The rest is filled with Kokkos::ALL.

Note

Though similar to std::submdspan, we think it it OK not to provide the remaining slice specifiers if they are all Kokkos::ALL iif the user specifies what is the expected rank of the input view. This ensures that the user will not face unexpected behaviors. Therefore, we allow the following:

auto sliced = slice<4>(view_of_rank_4, 1, 2);

which is strictly equivalent to:

auto sliced = subview(view_of_rank_4, 1, 2, Kokkos::ALL, Kokkos::ALL);

slice() [2/2]

template<typename ViewType, typename... Indices>
requires concepts::ViewOfRank<std::remove_reference_t<ViewType>, sizeof...(Indices)>

KOKKOS_FUNCTION constexpr auto Kokkos::utils::view::slice ( ViewType && view, Indices &&... indices )

constexpr

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