This struct provides a namespace for types and methods used to implement a space‐efficient value‐semantic array class representing a sequence of TYPE elements; TYPE must be convertible to either a bsl::int64_t. Specifically, it defines the types used to store the array's data, methods needed to externalize and unexternalize the array, and a method to determine the storage size to use for a given value.
