}Expand description
A multi-valued link included in the output shape.
Emitted as a correlated subquery using array_agg(ROW(...)::record).
Fields§
§alias: String§join: IrMultiLinkJoinJoin table or FK column identifying the source side.
subquery: IrSelectNested SELECT producing the linked objects.
link_properties: Vec<IrLinkProp>Extra scalar columns from a junction table (@prop syntax).
marker_offset: Option<usize>See IrScalarPointer::marker_offset.
single: boolRead as one object: (select .data … limit 1) is at most one row,
where a shape element on the link itself keeps the link’s many.
