Struct MatchCreateEdgeOperator 

pub struct MatchCreateEdgeOperator { /* private fields */ }

Operator for MATCH…CREATE queries Example: MATCH (a:Trial {id: 'NCT001'}), (b:Condition {mesh_id: 'D001'}) CREATE (a)-[:STUDIES]->(b) This operator takes matched nodes and creates edges between them

Trait Implementations

impl PhysicalOperator for MatchCreateEdgeOperator

fn next(&mut self, _store: &GraphStore) -> ExecutionResult<Option<Record>>

Get the next record from this operator (read-only operations)

fn next_mut( &mut self, store: &mut GraphStore, tenant_id: &str, ) -> ExecutionResult<Option<Record>>

fn reset(&mut self)

Reset the operator to start from the beginning

fn is_mutating(&self) -> bool

Returns true if this operator mutates the graph store
