Struct QueryOpts 

pub struct QueryOpts {
    pub reason: bool,
    pub union_default_graph: bool,
}

Evaluation options for eval_query_with. Every flag defaults to off, and off reproduces eval_query byte-for-byte — the W3C conformance suite runs with this default.

Fields

reason: bool

OWL 2 QL entailment by query rewriting — see eval_query_reasoned.

union_default_graph: bool

Union default graph (non-standard, opt-in): a pattern outside GRAPH matches the RDF merge of the default graph and every named graph, the mode Virtuoso / GraphDB / Jena TDB offer. A query with its own FROM keeps its FROM dataset; GRAPH ?g still enumerates the named graphs exactly as before. See Select::union_default.
