AscendIndexVStar

For params passed during index instance creation, set params.dim based on the actual situation.
The values of params.subSpaceDim and params.nlist must be the same as those during codebook training.

API definition	explicit AscendIndexVStar(const AscendIndexVstarInitParams& params);
Function	Constructor of AscendIndexVStar, which constructs the index of the corresponding dimension based on the value configured in params.
Input	const AscendIndexVstarInitParams& params: configuration parameters for construction. For details, see AscendIndexVstarInitParams.
Output	N/A
Return value	N/A
Restrictions	For details, see AscendIndexVstarInitParams.

API definition	AscendIndexVStar(const std::vector<int>& deviceList, bool verbose = false);
Function	Constructor of AscendIndexVStar, which constructs the index of an unknown input data dimension and hyperparameter based on deviceList.
Input	const std::vector<int>& deviceList: device ID. bool verbose: whether to enable verbose. If it is enabled, additional information will be displayed for some operations. The default value is false.
Output	N/A
Return value	N/A
Restrictions	The value of deviceList must be a valid device ID. Currently, only one device is supported. After creating an index instance using this constructor, you need to call LoadIndex to load the index instance that has been flushed to a drive before performing other operations.

API definition	AscendIndexVStar(const AscendIndexVStar&) = delete;
Function	Declares that the copy constructor of this Index class is void, that is, it cannot be copied.
Input	const AscendIndexVStar&: AscendIndexVStar object.
Output	N/A
Return value	N/A
Restrictions	N/A
