Struct FusionConfig 

pub struct FusionConfig {
    pub strategy: FusionStrategy,
    pub rrf_k: usize,
    pub weights: Option<AHashMap<String, f32>>,
    pub normalize_scores: bool,
}

Configuration for score fusion.

Fields

strategy: FusionStrategy

Fusion strategy

rrf_k: usize

RRF constant k (default 60, higher = more weight to lower ranks)

weights: Option<AHashMap<String, f32>>

Per-index weights for weighted fusion (None = equal weights)

normalize_scores: bool

Whether to normalize scores before fusion (for Comb methods)
