Enum QuantizedVector 

#[non_exhaustive]
pub enum QuantizedVector {
    Hot(Vec<f32>),
    Warm(Vec<u16>),
    Cold(PqVector),
}

A vector stored with temperature-based quantization.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Hot(Vec<f32>)

Full-precision f32 vector (hot tier).

Warm(Vec<u16>)

fp16-compressed vector (warm tier).

Cold(PqVector)

Product-quantized vector (cold tier).

Implementations

impl QuantizedVector

pub fn decompress(&self, codebook: Option<&PqCodebook>) -> Vec<f32>

pub fn temperature(&self) -> Temperature

Return the temperature tier.

pub fn compress( vector: &[f32], tier: Temperature, codebook: Option<&PqCodebook>, ) -> Self

Compress a full-precision vector to the specified tier.
