std::layout_left_padded
Defined in header <mdspan> | ||
|---|---|---|
template< std::size_t PaddingValue = std::dynamic_extent > struct layout_left_padded; | (since C++26) |
Every specialization of layout_left_padded is a LayoutMappingPolicy which provides a layout mapping that is similar to layout_left::mapping except that it has a padding stride.
Every specialization of layout_left_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_left_padded::mapping. The padding stride of the mapping is the second stride m.stride(1) which is guaranteed to be at least the first extent value m.extent(0), called extent to pad.
