int Add(int n, const float * x, int consecutive, int level);

Build a graph index.

Parameter	Description	Data Type	Value Range
n	Data volume.	int	≥ 1. It is recommended that the value be less than 1 billion.
x	Data.	const float*	The value cannot be null. The expected length is n × K_features (data volume × feature dimension).
consecutive	Block size.	int	[1, 31]
level	Quantization level.	int	[0, 5] 0: FP32 quantization. 1: SQ8U quantization. 2: SQ4U quantization. 3: FP16 quantization. 4: SQ8 quantization. 5: SQ4 quantization.

Data Type	Description
int	If the parameter value exceeds the value range, -1 is returned. Otherwise, 0 is returned.
