#include "tensorstore/chunk_layout.h"
struct tensorstore::ChunkLayout::ChunkAspectRatioBase
   
 : public MaybeHardConstraintSpan<double>;

Base type for specifying constraints on the aspect ratio of the write/read/codec chunk shape.

This type is defined as a subclass of MaybeHardConstraintSpan<double> rather than an alias for the benefit of stronger typing of the constructor parameter/accessor of GridView.

The actual constraints are specified using the usage-specific ChunkAspectRatioFor type.
