A quantized vector representation

Variants

Full(Vec<f32>)

Full precision f32 vector

Int8

Scalar quantized to int8

Fields

data: Vec<i8>

params: ScalarQuantParams

Int3

3-bit quantized (8 levels, packed 21 values per u64)

Fields

data: Vec<u64>

params: ScalarQuantParams

dimensions: usize

Binary

Binary quantized (packed bits)

Fields

data: Vec<u64>

dimensions: usize

Polar

Polar angle quantized (3-bit angles for pairs of dimensions) Each pair of dimensions → 1 angle quantized to 8 levels

Fields

data: Vec<u64>

Packed 3-bit angle indices (MSB-first, same packing as Int3)

dimensions: usize

Number of original dimensions (must be even)

seed: u32

Seed used for deterministic rotation
