Implementations

impl Affinity

pub fn apply_deltas(&mut self, d: &AffinityDeltas, ema_inertia: f64)

Apply LLM-evaluated deltas with EMA smoothing. ema_inertia ∈ [0, 1] — 0 means full update; v1 default is 0.5 (gain 0.5).

pub fn apply_time_decay(&mut self)

pub fn infer_label(&self) -> Option<RelationshipLabel>

Trait Implementations

impl Clone for Affinity

fn clone(&self) -> Affinity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Affinity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Affinity

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Affinity

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
