Struct dpiVectorInfo 

#[repr(C)]
pub struct dpiVectorInfo {
    pub format: u8,
    pub numDimensions: u32,

    pub numSparseValues: u32,
    pub sparseIndices: *mut u32,
}

This structure is used for providing or receiving information about a vector.

Fields

format: u8

Specifies the storage format for the vector. It should be one of the values from the enumeration dpiVectorFormat.

numDimensions: u32

Specifies the number of dimensions the vector contains.

dimensionSize: u8

Specifies the size (in bytes) of each dimension of the vector. This value does not need to be specified on input but is populated on output as a convenience.

dimensions: dpiVectorDimensionBuffer

Specifies the buffer for the dimensions. On input the buffer must remain valid for the duration of the call into ODPI-C. On output the buffer will remain valid as long as the vector object remains valid and the contents of the vector are not changed. See the dpiVectorDimensionBuffer union for more information.

For dense vectors, the length of this array is defined by the [dpiVectorInfo.numDimensions] member. For sparse vectors, the length of this array is defined by the [dpiVectorInfo.numSparseValues] member.

numSparseValues: u32

Specifies the number of values that a sparse vector contains that are non-zero. If this value is 0, the vector is considered a dense vector.

sparseIndices: *mut u32

Specifies an array of sparse vector indices. Each element in this array is the index of a non-zero value in the vector. The length of this array is defined by the [dpiVectorInfo.numSparseValues] member. If the vector is not a sparse vector, this value will be NULL.
