#include "tensorstore/chunk_layout.h"
struct tensorstore::ChunkLayout::ChunkElementsBase
   
 : public MaybeHardConstraintIndex;

Base type for specifying the target number of elements for a write/read/codec chunk.

This type is defined as a subclass of MaybeHardConstraintIndex 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 ChunkElementsFor type.
