Enum ShapeLabel 

pub enum ShapeLabel {
    LongTail,
    Uniform,
    Bimodal,
    InsufficientSamples,
}

Categorical label summarising the shape of the per-response score distribution. Promoted to a top-level agent hint on the retrieve response envelope (see ScoreDistribution::shape).

Variants

LongTail

Top score dominates the tail; max - median > 2 * iqr. Agents can trust top-1 as a confident match.

Uniform

Scores are roughly equi-spaced; no single item dominates. Dense ranking is inconclusive; consider a rerank or graph expansion.

Bimodal

Two distinct score clusters separated by a gap larger than iqr. Often a hybrid-lane artefact; look at per-lane scores.

InsufficientSamples

Fewer than K_MIN samples; shape cannot be distinguished from noise. score_quantile still emits (pure rank, well-defined for K >= 2), but distribution statistics are all zero.

Trait Implementations

impl Clone for ShapeLabel

fn clone(&self) -> ShapeLabel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeLabel

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ShapeLabel

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ShapeLabel

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
