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 = "neo4j"; 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 Some(row) = result.next().await {
        let node: Node = row.get("friend").unwrap();
        let name: String = node.get("name").unwrap();
            //process data
        }
    });
}

//Transactions
let txn = graph.start_txn().await.unwrap();
txn.run_queries(vec![
     query("CREATE (p:Person {id: 1})"),
     query("CREATE (p:Person {id: 2})"),
     query("CREATE (p:Person {id: 2})"),
]).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();

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");

```
