Enum QuantType 

#[repr(u8)]
pub enum QuantType {
    Scalar = 0,
    Product = 1,
    BinaryThreshold = 2,
    ResidualPq = 3,
}

Identifies the quantization method stored in a QUANT_SEG.

Variants

Scalar = 0

Scalar quantization (min-max per dimension).

Product = 1

Product quantization (codebook per subspace).

BinaryThreshold = 2

Binary threshold quantization (sign bit per dimension).

ResidualPq = 3

Residual product quantization.

Trait Implementations

impl Clone for QuantType

fn clone(&self) -> QuantType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuantType

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

Formats the value using the given formatter.

impl Hash for QuantType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for QuantType

fn eq(&self, other: &QuantType) -> 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 TryFrom<u8> for QuantType

type Error = u8

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
