col_major_nested

def col_major_nested(var shape: Coord) -> Layout[shape.element_types, *?]

Creates a column-major layout from a nested shape Coord.

For a nested shape ((a, b), (c, d)) the result has nested strides ((1, a), (a*b, a*b*c)) — col-major over the flattened shape, re-nested.

Currently restricted to all-static (compile-time) leaf dimensions and one level of nesting. For flat shapes use col_major.

Args:

  • ​shape (Coord): The nested shape as a Coord whose top-level elements are themselves Coords.

Returns:

Layout[shape.element_types, *?]: A Layout with the matching nested column-major strides.
