Struct GraphPostingList 

pub struct GraphPostingList { /* private fields */ }

Posting list paired with a (doc_id -> GraphPayload) map. The invariants of the underlying PostingList (sorted, unique doc ids) hold here as well.

Implementations

impl GraphPostingList

pub fn new() -> Self

pub fn try_from_parts( inner: PostingList, graph_payloads: BTreeMap<DocId, GraphPayload>, ) -> GraphPostingListResult<Self>

Construct a graph posting list while enforcing that every side-table key belongs to the underlying posting support.

pub fn to_posting_list(&self) -> PostingList

Phi: encode the graph payload map onto the underlying posting list’s payload fields. A versioned envelope preserves the original score, graph name, exact override state, and any values that already occupied reserved fields. Vertex and edge fields are also emitted as legacy mirrors for existing posting-list consumers.

The result composes with the standard posting payload policies; invert it with Self::from_posting_list to recover the graph view.

pub fn from_posting_list(pl: &PostingList) -> Self

Phi^{-1}: decode the versioned envelope and rebuild the (doc_id -> GraphPayload) side-table without losing the original payload. The legacy two-field representation remains readable, though values it never stored (graph name, base score, and None versus Some) cannot be reconstructed from legacy input.

pub fn try_set_graph_payload( &mut self, doc_id: DocId, payload: GraphPayload, ) -> GraphPostingListResult<()>

Attach graph metadata to a document already present in the support.

pub fn get_graph_payload(&self, doc_id: DocId) -> Option<&GraphPayload>

pub fn inner(&self) -> &PostingList

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn merge_union(&self, other: &Self) -> GraphPostingListResult<Self>

Union document support and ordinary payloads, while taking the set union of overlapping subgraph vertices and edges.

pub fn merge_intersection(&self, other: &Self) -> GraphPostingListResult<Self>

Intersect document support and ordinary payloads, while taking the set intersection of overlapping subgraph vertices and edges.

pub fn merge_union_with( &self, other: &Self, policy: SubgraphMergePolicy, ) -> GraphPostingListResult<Self>

Union with an explicit graph-metadata collision policy.

pub fn merge_intersection_with( &self, other: &Self, policy: SubgraphMergePolicy, ) -> GraphPostingListResult<Self>

Intersection with an explicit graph-metadata collision policy.

pub fn exclude(&self, other: &Self) -> Self
