Struct QueryOptions 

pub struct QueryOptions {
    pub union_default_graph: bool,
    pub sqlite_planner: bool,
    pub default_graph: Option<Vec<i64>>,
    pub named_graphs: Option<Vec<i64>>,

}

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).

Trait Implementations

impl Clone for QueryOptions

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for QueryOptions

fn default() -> Self

Returns the “default value” for a type.

impl Eq for QueryOptions

impl PartialEq for QueryOptions

fn eq(&self, other: &Self) -> bool

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
