Struct ExecutionContext 

pub struct ExecutionContext {
    pub document_store: Option<Arc<dyn DocumentStore>>,
    pub inverted_index: Option<Arc<dyn InvertedIndex>>,
    pub vector_indexes: BTreeMap<FieldName, Arc<dyn VectorIndex>>,
    pub stats: Option<IndexStats>,
    pub graph: Option<Arc<dyn GraphNeighborLookup>>,
}

Storage handles passed to every operator’s execute call.

Holding Arc<dyn ...> rather than borrows keeps the operator tree independent of how the engine owns its stores. The trade-off is one Arc::clone per operator at engine boundary; per-operator dispatch remains a single virtual call.

Fields

document_store: Option<Arc<dyn DocumentStore>>

inverted_index: Option<Arc<dyn InvertedIndex>>

vector_indexes: BTreeMap<FieldName, Arc<dyn VectorIndex>>

stats: Option<IndexStats>

graph: Option<Arc<dyn GraphNeighborLookup>>

Optional named graph (label-only neighbor lookup) for the graph-aware deep-fusion layers (Propagate, Conv, Pool). Held as a generic neighbor-lookup callback so this crate stays independent of uqa-graph.
