Enum QuantMode 

#[non_exhaustive]
#[repr(u16)]
pub enum QuantMode {
    Binary = 0,
    RaBitQ = 1,
    Bbq = 2,
    TernaryPacked = 3,
    TernarySimd = 4,

}

Quantization mode discriminator stored in the header.

Values are stable on disk — never reorder, only append.

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.

Binary = 0

RaBitQ = 1

Bbq = 2

TernaryPacked = 3

5 trits/byte cold layout, 1.6 bpw.

TernarySimd = 4

2 bpw expanded for SIMD hot path.

TurboQuant4b = 5

Sq8 = 6

Pq = 7

Itq3S = 8

Reserved discriminant for ITQ3_S (Interleaved Ternary Quantization).

PolarQuant = 9

Reserved discriminant for PolarQuant (Cartesian→polar 0.5 bpw).

Trait Implementations

impl Clone for QuantMode

fn clone(&self) -> QuantMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuantMode

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

Formats the value using the given formatter.

impl PartialEq for QuantMode

fn eq(&self, other: &QuantMode) -> 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.
