Enum EccMethod 

pub enum EccMethod {
    ScalarQuantization,
    ProductQuantization,
    DeltaCoding,
    RunLengthEncoding,
    HybridPQ,
}

Compression algorithm used by a codec.

Variants

ScalarQuantization

Uniform min-max scalar quantization to N bits.

ProductQuantization

Split vector into sub-blocks, scalar-quantize each independently.

DeltaCoding

Delta-encode values sorted by magnitude, then scalar-quantize.

RunLengthEncoding

Run-length encoding applied on quantized symbols.

HybridPQ

Product quantization followed by RLE on residual symbols.

Trait Implementations

impl Clone for EccMethod

fn clone(&self) -> EccMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EccMethod

impl Debug for EccMethod

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EccMethod

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EccMethod

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

Formats the value using the given formatter.

impl Eq for EccMethod

impl Hash for EccMethod

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 EccMethod

fn eq(&self, other: &EccMethod) -> 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 Serialize for EccMethod

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
