Struct ShortestPathOperator 

pub struct ShortestPathOperator { /* private fields */ }

Operator that finds shortest paths between source and target nodes.

For each input row containing source and target nodes, this operator computes the shortest path and outputs the path as a value.

Implementations

impl ShortestPathOperator

pub fn new( store: Arc<LpgStore>, input: Box<dyn Operator>, source_column: usize, target_column: usize, edge_type: Option<String>, direction: Direction, ) -> Self

Creates a new shortest path operator.

pub fn with_all_paths(self, all_paths: bool) -> Self

Sets whether to find all shortest paths.
