Enum QuantizedData 

pub enum QuantizedData {
    Full(Vec<f32>),
    Int8(QuantizedVector),
    Int4(Int4Vector),
    Binary(BinaryVector),
}

Unstable: unified quantized data container; variants may change with tier redesign.

Wraps the tier-specific vector types into a single enum for uniform storage and distance dispatch.

Variants

Full(Vec<f32>)

Full-precision f32 vector.

Int8(QuantizedVector)

INT8 quantized vector.

Int4(Int4Vector)

INT4 packed quantized vector.

Binary(BinaryVector)

Binary sign-bit vector.

Implementations

impl QuantizedData

pub fn tier(&self) -> QuantizationTier

Unstable: returns QuantizationTier which is itself Unstable.

pub fn dims(&self) -> usize

Unstable: dimension accessor; may be removed if QuantizedData gains a dims field.

pub fn storage_bytes(&self) -> usize

Unstable: storage byte count; may change with tier redesign.

pub fn from_f32(vector: &[f32], tier: QuantizationTier) -> Self

Unstable: quantization factory; tier dispatch logic may change.

pub fn to_f32(&self) -> Vec<f32>

Unstable: dequantization; output precision is tier-dependent.

pub fn promote(&self, target: QuantizationTier) -> Self

Unstable: tier promotion; re-quantizes via f32; may be rethought.

Dequantizes to f32 then re-quantizes at the target tier. Note: this does NOT recover lost information – it merely changes the storage format. INT4 -> INT8 promotion fills in new bits based on the dequantized approximation.

pub fn demote(&self, target: QuantizationTier) -> Self

Unstable: tier demotion; delegates to promote; may be removed.
