Struct QualityScore 

pub struct QualityScore {
    pub cosine: f32,
    pub judge_verdict: String,
    pub judge_model: String,
    pub embedder_id: String,
    pub sample_rate: f32,
}

Optional quality measurement attached to a Record when the proxy ran a shadow comparison between the compressed and the prose arm at sample rate.

Recorded ONCE at sample time – never re-derived from response text – so the audit ledger remains the single source of truth.

Fields

cosine: f32

Cosine similarity in [0.0, 1.0] of compressed-arm vs prose-arm response embeddings. Pin the embedder via embedder_id so values stay comparable across releases.

judge_verdict: String

Categorical judge verdict: "yes", "partial", "no", or "indeterminate". From the cheap comparator model.

judge_model: String

Identifier of the model used for judge_verdict; pinned for reproducibility (e.g. "claude-haiku-4.5").

embedder_id: String

Identifier of the embedder used for cosine; pinned (e.g. "sentence-transformers/all-MiniLM-L6-v2@v2.7.0").

sample_rate: f32

Sample rate in [0.0, 1.0] this record was drawn at; lets the aggregator weight per-record contributions when computing fleet-level quality.

Trait Implementations

impl Clone for QualityScore

fn clone(&self) -> QualityScore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QualityScore

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QualityScore

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for QualityScore

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
