+# SPARQL client
+
+The crate sparql-client is a SPARQL client
+based on Oxigraph components.
+
+It can be used to query SPARQL endpoints like Wikidata.
+
+## Usage example
+
+```
+use sparql_client::Client;
+
+#[tokio::main]
+async fn main() {
+ let client = Client::new("https://query.wikidata.org/sparql");
+ let railway_query = r#"
+#Cities connected by the Trans-Mongolian and Trans-Siberian Railway
+SELECT ?city ?cityLabel ?coordinates
+WHERE
+{
+ VALUES ?highway { wd:Q559037 wd:Q58767 }
+ ?highway wdt:P2789 ?city .
+ ?city wdt:P625 ?coordinates .
+ SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
+}
+ "#;
+
+ let solutions = client
+ .query(railway_query).await
+ .into_solutions()
+ .expect("No response has been found for the query.");
+
+ for city_solution in solutions {
+ println!("{:?}", city_solution);
+ }
+}
+```
