Per-query options.

Fields

union_default_graph: bool

Treat the default graph as the union of all graphs (Oxigraph’s union_default_graph).

sqlite_planner: bool

Let SQLite choose the join order instead of the oxilite planner (for benchmarking).

default_graph: Option<Vec<i64>>

Overrides the default graph with the merge of these graphs (term ids, 0 = default graph), like Oxigraph’s default_graph option.

named_graphs: Option<Vec<i64>>

Overrides the available named graphs (term ids).

reasoning: Reasoning

Entailment regime (default: none, like Oxigraph).

include_inferred: bool

Also match materialized inferences (quads_inf, see materialize()).

include_schema_graphs: bool

Match triples of the registered schema graphs (ontologies, shapes; see oxilite_core::registry). Default true: the dataset is the dataset. Set to false to query the data without the axioms and shapes that describe it.

var_types: BTreeMap<String, ValueType>

Value types known for variables (e.g. from a schema): comparisons on them compile to one typed comparison instead of a comparison per possible type. A value of another type then compares as unknown (false in a filter).

as_of: Option<String>

Read the store as it was at this version (HEAD~2, #42, @2026-09-01T00:00:00Z; see version::VersionRef). Needs a store with a change log; the store resolves it to Self::as_of_tick before compiling.

as_of_tick: Option<i64>

The resolved tick of Self::as_of.

versions: BTreeMap<String, i64>

Resolved ticks of the versions named by SERVICE <oxilite:version/REF> (by REF).

functions: Functions

Host functions callable by IRI (see crate::functions). A call to one is evaluated by the fallback evaluator; the rest of the query still compiles to SQL.
