Struct Edge 

pub struct Edge {
    pub id: String,
    pub source_id: String,
    pub target_id: String,
    pub relation: String,
    pub fact: Option<String>,
    pub valid_from: Option<DateTime<Utc>>,
    pub valid_until: Option<DateTime<Utc>>,
    pub recorded_at: DateTime<Utc>,
    pub confidence: f64,
    pub episode_id: Option<String>,
    pub metadata: Option<Value>,
}

An edge is a relationship between two entities. Edges are bi-temporal: valid_from/valid_until (real-world) + recorded_at (system).

Fields

id: String

source_id: String

target_id: String

relation: String

fact: Option<String>

valid_from: Option<DateTime<Utc>>

valid_until: Option<DateTime<Utc>>

recorded_at: DateTime<Utc>

confidence: f64

episode_id: Option<String>

metadata: Option<Value>

Implementations

impl Edge

pub fn new(source_id: &str, target_id: &str, relation: &str) -> Self

pub fn is_current(&self) -> bool

Check if this edge is currently valid (not invalidated).

pub fn is_valid_at(&self, at: DateTime<Utc>) -> bool

Check if this edge was valid at a specific point in time.
