Enum FusionStrategy 

pub enum FusionStrategy {
    Rrf,
    MinMax,
}

Fusion strategy for hybrid recall (CE-14).

Controls how vector and BM25 scores are combined when routing = Hybrid. MinMax is the server default since v0.11.2 (CEO architecture decision, DAK-1948). RecallRequest sends None by default, so the server default applies automatically.

Variants

Rrf

Reciprocal Rank Fusion (Cormack et al., SIGIR 2009). Formula: score(d) = Σ 1 / (k + rank(d)), k = 60. This variant is the Rust Default for ergonomic use; pass None in RecallRequest to let the server apply its own default (MinMax since v0.11.2).

MinMax

Weighted min-max normalization — server default since v0.11.2.

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() -> FusionStrategy

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.
