Struct ProvenancedTriple 

pub struct ProvenancedTriple {
    pub subject: String,
    pub predicate: String,
    pub object: String,
    pub source_id: String,
    pub confidence: f64,
    pub timestamp: u64,
}

A knowledge triple with provenance and confidence metadata.

Fields

subject: String

Subject.

predicate: String

Predicate.

object: String

Object.

source_id: String

Source identifier that contributed this triple.

confidence: f64

Confidence in [0, 1] from the originating source.

timestamp: u64

Timestamp of the triple (epoch seconds, 0 if unknown).

Implementations

impl ProvenancedTriple

pub fn new( subject: impl Into<String>, predicate: impl Into<String>, object: impl Into<String>, source_id: impl Into<String>, confidence: f64, ) -> Self

Create a new provenanced triple.

pub fn with_timestamp(self, ts: u64) -> Self

Set the timestamp.

pub fn triple_key(&self) -> (String, String, String)

Canonical key for deduplication: (subject, predicate, object).

Trait Implementations

impl Clone for ProvenancedTriple

fn clone(&self) -> ProvenancedTriple

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProvenancedTriple

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

Formats the value using the given formatter.

impl PartialEq for ProvenancedTriple

fn eq(&self, other: &ProvenancedTriple) -> 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.
