Enum FusionStrategy 

pub enum FusionStrategy {
    Rrf {
        k: usize,
    },
    Weighted {
        weights: Vec<f64>,
    },
    Union,
    VectorOnly,
}

Strategy for fusing ranked result lists from multiple retrieval sources.

Variants

Rrf

Reciprocal Rank Fusion. Uses only ranks; robust to different score scales.

Fields

k: usize

Weighted

Weighted linear combination. Min-max normalizes each source to [0,1] first. Weights are normalized to sum to 1.0; negatives clamped to 0; all-zero falls back to equal.

Fields

weights: Vec<f64>

Union

Take all hits; keep the max score per entity_id.

VectorOnly

Drop text hits; return vector hits only.

Trait Implementations

impl Clone for FusionStrategy

fn clone(&self) -> FusionStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FusionStrategy

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

Formats the value using the given formatter.

impl Default for FusionStrategy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FusionStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FusionStrategy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
