Struct Relationship 

pub struct Relationship {

    pub id: Value,
    pub from_id: Value,
    pub to_id: Value,
    pub rel_type: String,
    pub description: Option<String>,

}

A stored relationship.

Fields

id: Value

from_id: Value

to_id: Value

rel_type: String

description: Option<String>

valid_from: Value

valid_until: Option<Value>

confidence: f64

Posterior mean of the edge’s Beta distribution — alpha / (alpha + beta). Kept in sync with the counts on every write; this is what read paths score on.

alpha: Option<f64>

Accumulated corroborating evidence (Beta α). None only on an edge the schema migration has not reached yet.

beta: Option<f64>

Accumulated contradicting evidence (Beta β).

self_reinforcements: Option<i64>

How many corroborations came from the agent itself — counted, never laundered into confidence. Populated from Phase 1 increment 2 onward.

last_reinforced: Option<Value>

When this relationship was last reinforced (Bayesian corroboration). Used by temporal decay: effective_confidence = confidence × 0.5^(days_since / half_life).

source: Option<String>

Implementations

impl Relationship

pub fn id_string(&self) -> String

Get the record ID as a string.

pub fn evidence(&self) -> Evidence

The edge’s accumulated evidence, falling back to the prior implied by its mean when the counts have not been backfilled yet.

pub fn edge_evidence(&self) -> EdgeEvidence

The edge’s full evidence state — Beta counts plus coherence tally. This is what a confidence-moving observation is applied to.

Trait Implementations

impl Clone for Relationship

fn clone(&self) -> Relationship

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Relationship

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Relationship

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Relationship

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
