Enum VectorData 

pub enum VectorData {
    F32(Vec<f32>),
    F16(Vec<f16>),
    BF16(Vec<bf16>),
}

Vector data supporting multiple precision formats.

Stores vectors in their native precision format to minimize memory usage. Provides conversion methods for distance calculations.

Variants

F32(Vec<f32>)

Full precision f32 vector

F16(Vec<f16>)

Half precision f16 vector (50% memory reduction)

BF16(Vec<bf16>)

Brain float bf16 vector (50% memory reduction, ML-optimized)

Implementations

impl VectorData

pub fn from_f32_slice(data: &[f32], precision: VectorPrecision) -> Self

Creates a new VectorData from an f32 slice with the specified precision.

Arguments

• data - Source f32 data
• precision - Target precision format

Example

use velesdb_core::half_precision::{VectorData, VectorPrecision};

let v = VectorData::from_f32_slice(&[0.1, 0.2, 0.3], VectorPrecision::F16);
assert_eq!(v.len(), 3);

pub fn from_f32_vec(data: Vec<f32>, precision: VectorPrecision) -> Self

Creates a new VectorData from an f32 vec, taking ownership.

pub const fn precision(&self) -> VectorPrecision

Returns the precision of this vector.

pub fn len(&self) -> usize

Returns the dimension (length) of the vector.

pub fn is_empty(&self) -> bool

Returns true if the vector is empty.

pub fn memory_size(&self) -> usize

Returns the memory size in bytes.

pub fn to_f32_vec(&self) -> Vec<f32>

Converts the vector to f32 for calculations.

For F32 vectors, this clones the data. For F16/BF16 vectors, this converts each element.

pub fn as_f32_slice(&self) -> Option<&[f32]>

Returns a reference to the underlying f32 data if precision is F32.

Returns None for F16/BF16 vectors.

pub fn convert(&self, target: VectorPrecision) -> Self

Converts to another precision format.
