}

Configuration for the recall scoring pipeline. All fields have sensible defaults matching current behavior.

Fields

relevance_weight: f64

Weight of RRF/fusion score. Default 0.70.

importance_weight: f64

Weight of decay-adjusted salience. Default 0.20.

temporal_weight: f64

Weight of pure recency. Default 0.10.

temporal_half_life_days: f64

Days for temporal score to halve. Default 30.0.

decay_model: DecayModel

Decay model to apply to salience. Default Exponential.

candidate_multiplier: u32

Candidates per retrieval path before fusion = limit × this. Default 20.

candidate_limit: Option<u32>

Explicit max candidates per retrieval path before fusion. When None, candidate_multiplier keeps the legacy behavior.

fuse_strategy: FusionStrategy

Strategy used to fuse retrieval-source candidate lists. Default RRF k=60.

min_score: f64

Minimum composite score to include in results. Default 0.0.

min_salience: f64

Minimum raw salience to include in results. Default 0.0.

include_breakdown: bool

Include per-component score breakdowns in recall responses. Default false.

Implementations

impl RecallConfig

pub fn validate(&self) -> Result<(), RuntimeError>

Validate that the config is internally consistent.

Rejects:

• Negative weights
• All three weights summing to zero (no scoring signal)
• Non-positive temporal half-life

Trait Implementations

impl Clone for RecallConfig

fn clone(&self) -> RecallConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecallConfig

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

Formats the value using the given formatter.

impl Default for RecallConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RecallConfig

where RecallConfig: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for RecallConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
