EdgeHistoryEvent

Struct EdgeHistoryEvent 

Source
pub struct EdgeHistoryEvent {
    pub edge_type: String,
    pub commit: u64,
    pub event: EdgeEvent,
    pub rule: Option<String>,
}
Expand description

A single add-or-retract event for an edge between two nodes.

Fields§

§edge_type: String§commit: u64

0-based WAL frame index of the commit that produced this event.

§event: EdgeEvent§rule: Option<String>

Some(rule_name) for rule-derived edges, None for manually written edges. Derived edges are represented by DerivedEdgeAdded / DerivedEdgeRetracted WAL markers (discriminants 18/19) written by log_then_apply_with after each rule-firing mutation; see derived_edge_state_records_not_wal_logged_markers_are in rules.rs.
