Enum OperatorOutput 

pub enum OperatorOutput {
    Posting(PostingList),
    Graph(GraphPostingList),
    Generalized(GeneralizedPostingList),
}

Materialised value produced by a physical OperatorTree node.

Most operators preserve one document id per row and therefore emit a PostingList. Graph operators retain their subgraph side table in a GraphPostingList, while join operators preserve an ordered tuple of document ids in a GeneralizedPostingList. Keeping the carriers distinct prevents set operations from silently applying ordinary payload precedence to graph metadata or comparing synthetic join enumeration positions.

Variants

Posting(PostingList)

Graph(GraphPostingList)

Generalized(GeneralizedPostingList)
