Rustプロジェクト作成

cargo new arango-rust-test

各ファイル

Cargo.toml

[package]
name = "arango-rust-test"
version = "0.1.0"
edition = "2021"

tokio = { version = "1", features = ["full"] }
use anyhow::Error;

use arangors_lite::{AqlQuery, Connection};

    // (Recommended) Handy functions
    let conn = Connection::establish_jwt("http://localhost:8529", "ユーザーID", "パスワード")
    .await
    .unwrap();

    let database = conn.db("test").await.unwrap();
    let aql = AqlQuery::new("FOR u IN User LIMIT 3 RETURN u");
    println!("{:?}", aql);
    println!("{:?}", serde_json::to_string(&aql).unwrap());

    let resp: Vec<Value> = database.aql_query(aql).await.unwrap();
    println!("{:?}", resp);
    Ok(())
}

#[tokio::main]
async fn main() {

ビルド

cargo build

実行

.\target\debug\arango-rust-test.exe
