You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: main.rs
    path of file: ./repos/surrealdb/lib/examples/transaction
    
    the code of the file until where you have to start completion: use surrealdb::engine::remote::ws::Ws;
use surrealdb::opt::auth::Root;
use surrealdb::sql::statements::BeginStatement;
use surrealdb::sql::statements::CommitStatement;
use surrealdb::Surreal;

#[tokio::main]
async fn main() -> surrealdb::Result<()> {
	let db = Surreal::new::<Ws>("localhost:8000").await?;

	db.signin(Root {

    
async fn main() -> surrealdb::Result<()> {
	let db = Surreal::new::<Ws>("localhost:8000").await?;

	db.signin(Root {
		username: "root",
		password: "root",
	})
	.await?;

	db.use_ns("namespace").use_db("database").await?;

	#[rustfmt::skip]
    let response = db

        // Start transaction
        .query(BeginStatement)

        // Setup accounts
        .query("
            CREATE account:one SET balance = 135605.16;
            CREATE account:two SET balance = 91031.31;
        ")

        // Move money
        .query("
            UPDATE account:one SET balance += 300.00;
            UPDATE account:two SET balance -= 300.00;
        ")

        // Finalise
        .query(CommitStatement)
        .await?;

	// See if any errors were returned
	response.check()?;

	Ok(())
