    Composite(Vec<RerankerConfig>),
}

Post-retrieval reranking configuration.

Variants

None

Disable reranking.

Diversity

Promote diversity using maximal marginal relevance.

Fields

lambda: f32

Relevance-vs-diversity balance in the range [0.0, 1.0].

weight: f32

Stage weight used by the composite reranker.

Recency

Boost recently created records.

Fields

boost: f32

Strength of the recency boost.

half_life_days: f32

Exponential half-life in days.

weight: f32

Stage weight used by the composite reranker.

Composite(Vec<RerankerConfig>)

Apply multiple rerankers in sequence.

Trait Implementations

impl Clone for RerankerConfig

fn clone(&self) -> RerankerConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RerankerConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RerankerConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RerankerConfig

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
