Struct ExistingEdge 

pub struct ExistingEdge {
    pub subject_key: String,
    pub relation: String,
    pub object_key: String,
    pub valid_from: DateTime<FixedOffset>,
    pub valid_to: Option<DateTime<FixedOffset>>,
}

An edge already in the graph, as the resolver sees it for conflict checks.

Self-describing: the tuple (subject_key, relation, object_key, valid_from) is the edge’s identity within a scope — the same tuple the commit path MERGEs on — so a resolver’s close decision carries everything needed to find the edge again, with no backend-internal id. valid_to is None while the edge is current and Some(t) once it was superseded at t. Only current edges take part in conflict resolution; closed edges are history.

Fields

subject_key: String

Resolved key of the subject node.

relation: String

The relation label.

object_key: String

Resolved key of the object node.

valid_from: DateTime<FixedOffset>

When the fact became true — part of the edge’s identity.

valid_to: Option<DateTime<FixedOffset>>

None while the edge is current; Some(t) once superseded at t.

Trait Implementations

impl Clone for ExistingEdge

fn clone(&self) -> ExistingEdge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExistingEdge

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

Formats the value using the given formatter.

impl PartialEq for ExistingEdge

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