Struct Relationship 

pub struct Relationship {
    pub from_entity: EntityId,
    pub to_entity: EntityId,
    pub relationship_type: RelationshipType,
    pub confidence: f32,
    pub valid_time: ValidTimeRange,
    pub transaction_time: TransactionTime,
    pub properties: HashMap<String, String>,
}

A relationship between two entities in the knowledge graph.

Fields

from_entity: EntityId

Source entity ID.

to_entity: EntityId

Target entity ID.

relationship_type: RelationshipType

Type of relationship.

confidence: f32

Confidence score (0.0 to 1.0).

valid_time: ValidTimeRange

Bitemporal: when this relationship was valid.

transaction_time: TransactionTime

Bitemporal: when this relationship was recorded.

properties: HashMap<String, String>

Optional properties as key-value pairs.

Implementations

impl Relationship

pub fn new( from_entity: EntityId, to_entity: EntityId, relationship_type: RelationshipType, ) -> Self

Creates a new relationship with default temporal values.

pub fn with_confidence(self, confidence: f32) -> Self

Sets the confidence score.

pub fn with_valid_time(self, valid_time: ValidTimeRange) -> Self

Sets the valid time range.

pub fn with_property( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Adds a property to the relationship.

pub fn is_valid_at(&self, timestamp: i64) -> bool

Returns true if this relationship is valid at the given time.

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 PartialEq for Relationship

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
