Adds additional constraints.

Parameters:
rank: int | None = None

Specifies the number of dimensions.

inner_order: Sequence[int] | None = None

Permutation specifying the element storage order within the innermost chunks. Corresponds to the JSON ChunkLayout.inner_order member. This must be a permutation of [0, 1, ..., rank-1]. Lexicographic order (i.e. C order/row-major order) is specified as [0, 1, ..., rank-1], while colexicographic order (i.e. Fortran order/column-major order) is specified as [rank-1, ..., 1, 0].

inner_order_soft_constraint: Sequence[int] | None = None

Specifies a preferred value for inner_order rather than a hard constraint. Corresponds to the JSON ChunkLayout.inner_order_soft_constraint member. If inner_order is also specified, it takes precedence.

Common constraints on write, read, and codec chunks. Corresponds to the JSON ChunkLayout.chunk member. The shape and elements constraints apply only to write and read chunks, while the aspect_ratio constraints apply to write, read, and codec chunks.

write_chunk: ChunkLayout.Grid | None = None

Constraints on write chunks. Corresponds to the JSON ChunkLayout.write_chunk member.
