pub fn routed_triple_pattern(
query: &str,
) -> Result<Option<RoutedTriplePattern>, SparqlError>Expand description
Classify queries whose graph access is exactly one default-graph triple pattern. Solution modifiers (projection, LIMIT, aggregate wrappers) do not change the underlying range access, but named graphs, FROM, joins, filters, paths, and other algebra need the full SPARQL evaluator.
