Struct SourceContribution 

pub struct SourceContribution {
    pub retriever_id: String,
    pub original_rank: Option<usize>,
    pub original_score: Option<f32>,
    pub normalized_score: Option<f32>,
    pub contribution: f32,
}

Contribution from a single retriever to a document’s final score.

Fields

retriever_id: String

Identifier for this retriever (e.g., “bm25”, “dense_vector”).

original_rank: Option<usize>

Original rank in this retriever’s list (0-indexed, None if not present).

original_score: Option<f32>

Original score from this retriever (None for rank-based methods or if not present).

normalized_score: Option<f32>

Normalized score (for score-based methods, None for rank-based).

contribution: f32

How much this source contributed to the final fused score.

For RRF: 1/(k + rank) or weight / (k + rank) for weighted. For CombSUM: normalized score. For CombMNZ: normalized score × overlap count.

Trait Implementations

impl Clone for SourceContribution

fn clone(&self) -> SourceContribution

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceContribution

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SourceContribution

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SourceContribution

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
