Expand from nodes to their neighbors.

Fields

from_variable: String

Source node variable.

to_variable: String

Target node variable to bind.

edge_variable: Option<String>

Edge variable to bind (optional).

direction: ExpandDirection

Direction of expansion.

edge_types: Vec<String>

Edge type filter (empty = match all types, multiple = match any).

min_hops: u32

Minimum hops (for variable-length patterns).

max_hops: Option<u32>

Maximum hops (for variable-length patterns).

input: Box<LogicalOperator>

Input operator.

path_alias: Option<String>

Path alias for variable-length patterns (e.g., p in p = (a)-[*1..3]->(b)). When set, a path length column will be output under this name.

path_mode: PathMode

Path traversal mode (WALK, TRAIL, SIMPLE, ACYCLIC).
