Struct QuantizedVector 

pub struct QuantizedVector {
    pub dim: u32,
    pub scheme: QuantScheme,
    pub scale: f32,
    pub zero_point: i8,
    pub min_val: f32,
    pub data: Vec<u8>,
}

Quantized embedding vector with compression parameters

Fields

dim: u32

Vector dimension (number of elements)

scheme: QuantScheme

Quantization scheme used

scale: f32

Scaling factor for dequantization

zero_point: i8

Zero-point offset for optimal range utilization

min_val: f32

Minimum value in the original data (for reconstruction)

data: Vec<u8>

Packed quantized data (actual byte representation)

Implementations

impl QuantizedVector

pub fn new( dim: u32, scheme: QuantScheme, scale: f32, zero_point: i8, min_val: f32, data: Vec<u8>, ) -> Self

Creates a new quantized vector

pub fn data_size(&self) -> usize

Returns the size in bytes (excluding metadata)

pub fn compression_ratio(&self) -> f32

Returns the compression ratio compared to F32 representation

Trait Implementations

impl Clone for QuantizedVector

fn clone(&self) -> QuantizedVector

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QuantizedVector

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QuantizedVector

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for QuantizedVector

fn eq(&self, other: &QuantizedVector) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for QuantizedVector

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
