# std::layout_right_padded

From cppreference.com
< cpp‎ | container‎ | mdspan

Defined in header `<mdspan>` |  |
template< std::size_t PaddingValue = std::dynamic_extent > struct layout_right_padded; |  | (since C++26)

Every specialization of `layout_right_padded` is a LayoutMappingPolicy which provides a layout mapping that is similar to `layout_right::mapping` except that it has a padding stride.

Every specialization of `layout_right_padded` is TriviallyCopyable, and std::is_trivially_default_constructible_v <T> is true for any such specialization `T`.

Let m be the instance of the mapping type `layout_right_padded::mapping`. The padding stride of the mapping is the second to last stride m.stride(rank() - 2) which is guaranteed to be at least the last extent value m.extent(rank() - 1), called extent to pad.
