Defined in header <mdspan>
struct layout_left;		(since C++23)

layout_left is a LayoutMappingPolicy which provides a layout mapping where the leftmost extent has stride 1, and strides increase left-to-right as the product of extents.

layout_left is a TrivialType.	(until C++26)
layout_left is TriviallyCopyable, and std::is_trivially_default_constructible_v<layout_left> is true.	(since C++26)

Nested class templates

mapping
