AscendIndexBinaryFlat

API definition	AscendIndexBinaryFlat(int dims, AscendIndexBinaryFlatConfig config = AscendIndexBinaryFlatConfig(), bool usedFloat = false);
Function	Constructor of AscendIndexBinaryFlat, which is used to generate AscendIndexBinaryFlat whose dimension is dims and set resources on the device based on the value configured in config.
Input	int dims: dimensions of a group of feature vectors managed by AscendIndexBinaryFlat. AscendIndexBinaryFlatConfig config: resource configuration on the device. bool usedFloat: used to improve the performance of the search mode (search) for binary features and retrieval features of the float type. The default value is false. The value true means to improve performance.
Output	N/A
Return value	N/A
Restrictions	dims∈ {256, 512, 1024}

API definition	AscendIndexBinaryFlat(const faiss::IndexBinaryFlat *index, AscendIndexBinaryFlatConfig config = AscendIndexBinaryFlatConfig(), bool usedFloat = false);
Function	Constructor of AscendIndexBinaryFlat, which is used to create a retrieval index on the Ascend based on an existing index.
Input	*const faiss::IndexBinaryFlat index: index resources on the CPU. AscendIndexBinaryFlatConfig config: resource configuration on the device. bool usedFloat: used to improve the performance of the search mode (search) for binary features and retrieval features of the float type. The default value is false. The value true** means to improve performance.
Output	N/A
Return value	N/A
Restrictions	index must be a valid CPU index pointer. index->d ∈ {256, 512, 1024}. index->ntotal is the smaller value between the actual memory capacity of the chip and 1e9.

API definition	AscendIndexBinaryFlat(const faiss::IndexBinaryIDMap *index, AscendIndexBinaryFlatConfig config = AscendIndexBinaryFlatConfig(), bool usedFloat = false);
Function	Constructor of AscendIndexBinaryFlat, which is used to create a retrieval index on the Ascend based on an existing index.
Input	*const faiss::IndexBinaryIDMap index: index resources on the CPU. AscendIndexBinaryFlatConfig config: resource configuration on the device. bool usedFloat: used to improve the performance of the search mode (search) for binary features and retrieval features of the float type. The default value is false. The value true** means to improve performance.
Output	N/A
Return value	N/A
Restrictions	index must be a valid faiss::IndexBinaryIDMap pointer. index->index must be a valid IndexBinaryFlat pointer. index->index->d ∈ {256, 512, 1024}. index->index->ntotal is the smaller value between the actual memory capacity of the chip and 1e9.

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