Neo4rs CircleCI

Neo4rs is a native rust driver implemented using bolt 4.1 specification

Getting Started

```rust
//Run a query let uri = "127.0.0.1:7687".toowned(); let user = "neo4j"; let pass = "neo"; let graph = Graph::new(&uri, user, pass).await.unwrap(); assert!(graph.run(query("RETURN 1")).await.isok());

//Concurrent queries
let uri = "127.0.0.1:7687";
let user = "neo4j";
let pass = "neo";
let graph = Arc::new(Graph::new(&uri, user, pass).await.unwrap());
for _ in 1..=42 {
    let graph = graph.clone();
    tokio::spawn(async move {
        let mut result = graph.execute(
       query("MATCH (p:Person {name: $name}) RETURN p").param("name", "Mark")
    ).await.unwrap();
        while let Ok(Some(row)) = result.next().await {
        let node: Node = row.get("p").unwrap();
        let name: String = node.get("name").unwrap();
            println!("{}", name);
        }
    });
}

//Transactions
let mut txn = graph.start_txn().await.unwrap();
txn.run_queries(vec![
    query("CREATE (p:Person {name: 'mark'})"),
    query("CREATE (p:Person {name: 'jake'})"),
    query("CREATE (p:Person {name: 'luke'})"),
])
.await
.unwrap();
txn.commit().await.unwrap(); //or txn.rollback().await.unwrap();


//Create and parse relationship
let mut result = graph
    .execute(query("CREATE (p:Person { name: 'Mark' })-[r:WORKS_AT {as: 'Engineer'}]->(neo) RETURN r"))
    .await
    .unwrap();

let row = result.next().await.unwrap().unwrap();

let relation: Relation = row.get("r").unwrap();
assert!(relation.id() > 0);
assert!(relation.start_node_id() > 0);
assert!(relation.end_node_id() > 0);
assert_eq!(relation.typ(), "WORKS_AT");
assert_eq!(relation.get::<String>("as").unwrap(), "Engineer");

//Handle points
let mut result = graph
    .execute(query(
        "RETURN point({ longitude: 56.7, latitude: 12.78, height: 8 }) AS point",
    ))
    .await
    .unwrap();
let row = result.next().await.unwrap().unwrap();
let point: Point3D = row.get("point").unwrap();
assert_eq!(point.sr_id(), 4979);
assert_eq!(point.x(), 56.7);
assert_eq!(point.y(), 12.78);
assert_eq!(point.z(), 8.0);

```
