Enum VectorValue 

pub enum VectorValue {
    Dense(Vec<f32>),
    Sparse {
        indices: Vec<u32>,
        values: Vec<f32>,
    },
}

Vector value type for efficient storage of numerical vectors

Variants

Dense(Vec<f32>)

Dense vector - most common, stores all values

Sparse

Sparse vector - stores only non-zero values with indices

Fields

indices: Vec<u32>

values: Vec<f32>
