Struct neo4rs::Graph

pub struct Graph { /* private fields */ }

A neo4j database abstraction. This type can be cloned and shared across threads, internal resources are reference-counted.

Implementations

impl Graph

pub async fn connect(config: Config) -> Result<Self>

Connects to the database with configurations provided.

You can build a config using ConfigBuilder::default().

pub async fn new( uri: impl Into<String>, user: impl Into<String>, password: impl Into<String> ) -> Result<Self>

Connects to the database with default configurations

pub async fn start_txn(&self) -> Result<Txn>

Starts a new transaction on the configured database. All queries that needs to be run/executed within the transaction should be executed using either Txn::run or Txn::execute

pub async fn start_txn_on(&self, db: impl Into<Database>) -> Result<Txn>

Starts a new transaction on the provided database. All queries that needs to be run/executed within the transaction should be executed using either Txn::run or Txn::execute

pub async fn run(&self, q: Query) -> Result<()>

Runs a query on the configured database using a connection from the connection pool, It doesn’t return any [RowStream] as the run abstraction discards any stream.

Use Graph::run for cases where you just want a write operation

use Graph::execute when you are interested in the result stream

pub async fn run_on(&self, db: &str, q: Query) -> Result<()>

Runs a query on the provided database using a connection from the connection pool. It doesn’t return any [RowStream] as the run abstraction discards any stream.

Use Graph::run for cases where you just want a write operation

use Graph::execute when you are interested in the result stream

pub async fn execute(&self, q: Query) -> Result<DetachedRowStream>

Executes a query on the configured database and returns a [DetachedRowStream]

pub async fn execute_on(&self, db: &str, q: Query) -> Result<DetachedRowStream>

Executes a query on the provided database and returns a [DetaRowStream]

Trait Implementations

impl Clone for Graph

fn clone(&self) -> Graph

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
