Module rusted_cypher::cypher

Provides structs used to interact with the cypher transaction endpoint

The types declared in this module, save for Statement, don't need to be instantiated directly, since they can be obtained from the GraphClient.

Examples

Execute a single query

let graph = GraphClient::connect(URL).unwrap();

graph.cypher().exec("CREATE (n:CYPHER_QUERY {value: 1})").unwrap();
let result = graph.cypher().exec("MATCH (n:CYPHER_QUERY) RETURN n.value AS value").unwrap();

// Iterate over the results
for row in result.rows() {
    let value = row.get::<i32>("value").unwrap(); // or: let value: i32 = row.get("value");
    assert_eq!(value, 1);
}

Execute multiple queries

let mut query = graph.cypher().query()
    .with_statement("MATCH (n:SOME_CYPHER_QUERY) RETURN n.value as value")
    .with_statement("MATCH (n:OTHER_CYPHER_QUERY) RETURN n");

let results = query.send().unwrap();

for row in results[0].rows() {
    let value: i32 = row.get("value").unwrap();
    assert_eq!(value, 1);
}

Start a transaction

let (transaction, results) = graph.cypher().transaction()
    .with_statement("MATCH (n:TRANSACTION_CYPHER_QUERY) RETURN n")
    .begin().unwrap();
