GetFeatures

API Definition	APP_ERROR GetFeatures(int n, float16_t features, const idx_t indices) override
Function	Queries n feature vectors with specified subscript indexes.
Input	int n: number of vectors to be obtained in the base library. *const idx_t indices**: index values corresponding to n vectors to be obtained in the base library.
Output	*float16_t features*: The length of the feature vectors corresponding to the subscript indexes is n x vector dimension dim*.
Return Value	APP_ERROR: return status. For details, see Return Code Reference.
Restrictions	indices: The index range of each feature is [0, ntotal). ntotal can be obtained through the GetNTotal API. n: The value range is [0, capacity].
