Struct HorizontalAggregateOp 

pub struct HorizontalAggregateOp {
    pub list_column: String,
    pub entity_kind: EntityKind,
    pub function: AggregateFunction,
    pub property: String,
    pub alias: String,
    pub input: Box<LogicalOperator>,
}

Per-row aggregation over a list-valued column (horizontal aggregation, GE09).

For each input row, reads a list of entity IDs from list_column, accesses property on each entity, computes the aggregate, and emits the scalar result.

Fields

list_column: String

The list column name (e.g., _path_edges_p).

entity_kind: EntityKind

Whether the list contains edge IDs or node IDs.

function: AggregateFunction

The aggregate function to apply.

property: String

The property to access on each entity.

alias: String

Output alias for the result column.

input: Box<LogicalOperator>

Input operator.
