Enum CodecProfile 

pub enum CodecProfile {
    Raw,
    Q8,
    Q4,
    Turbo,
    Fib,
    Polar,
    Qjl,
}

Codec profiles available for governance selection.

Variants

Raw

Uncompressed representation

Q8

8-bit quantization

Q4

4-bit quantization

Turbo

Turbo-quant accelerated codec (symmetric; reconstructs original vector)

Fib

Fibonacci-weighted precision codec (symmetric; reconstructs original vector)

Polar

Polar-only quantization (asymmetric; score_inner_product / score_l2 only)

Qjl

QJL random-projection sketch (asymmetric; fixed-size inner-product estimator)

Implementations

impl CodecProfile

pub fn default_degradation_threshold(&self) -> f64

Returns the default degradation threshold for this profile.

pub fn is_high_fidelity(&self) -> bool

Returns true if this is a high-fidelity profile.

pub fn is_asymmetric(&self) -> bool

Returns true if this codec is asymmetric (cannot reconstruct the original vector from compressed bytes alone). For asymmetric codecs the wire format is a sketch/code, and the caller must use score_inner_product / score_l2 against a known query.

pub fn estimated_compression_ratio(&self) -> f64

Returns estimated compression ratio for this profile.

Trait Implementations

impl Clone for CodecProfile

fn clone(&self) -> CodecProfile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodecProfile

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CodecProfile

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CodecProfile

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

Formats the value using the given formatter.

impl Hash for CodecProfile

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 CodecProfile

fn eq(&self, other: &CodecProfile) -> 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 CodecProfile

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
