Fields§

§query_type: QueryType§select_variables: Vec<Variable>§where_clause: Algebra§order_by: Vec<OrderCondition>§group_by: Vec<GroupCondition>§having: Option<Expression>§limit: Option<usize>§offset: Option<usize>§distinct: bool§reduced: bool§construct_template: Vec<TriplePattern>§prefixes: HashMap<String, String>§base_iri: Option<String>§dataset: DatasetClause§projection_items: Vec<ProjectionItem>

Ordered SELECT projection items (parallel to select_variables, but also carrying (Expression AS ?v) / aggregate projections). Empty when the query is SELECT * or is not a SELECT query.

§describe_targets: Vec<DescribeTarget>

Explicit DESCRIBE targets (IRIs and variables). Empty for non-DESCRIBE queries and for DESCRIBE * (see describe_all).

§describe_all: bool

true for DESCRIBE *, which describes every in-scope variable binding rather than an explicit target list.
