constexpr | mapping (const mapping< OtherExtents > &m) noexcept |
Construct the mapping from another mapping with a different extents type. | |
template<class OtherExtents , class E = extents_type, std::enable_if_t<(E::rank()<=1), int > = 0, std::enable_if_t< std::is_constructible_v< extents_type, OtherExtents >, int > = 0> | |
constexpr | mapping (const layout_right::mapping< OtherExtents > &m) noexcept |
Construct the mapping from a layout_right. | |

constexpr index_type | operator() (Indices... ii) const noexcept |
Compute the offset i0 + E(0)*(i1 + E(1)*(i2 + E(2)*i3)) | |
