in rust, how to convert result query into object or json without declare struct ?

[randiekas]

iam using actix, in previous version (0.8) the result query as an array object, so i can direct response from query process
let res = dbs.process(parse(query.as_str()).unwrap(), &ses, None, false).await.unwrap(); Ok(HttpResponse::Ok().json(res))

how to get result as array object in version 0.9 ?

let res = DB.query("select * from account").await.unwrap();
so i can directly result of the query as an result json like this
let res = DB.query("select * from account").await.unwrap(); Ok(HttpResponse::Ok().json(res))

You need to cast result to Vec<serde_json::Value> or Option<serde_json::Value> for example.

let articles: Vec<serde_json::Value> = DB.query("SELECT * FROM article LIMIT 25 FETCH revision").await.unwrap().take(0).unwrap();
let title = articles.first().unwrap().get("revision").unwrap().get("title").unwrap();

let article_option: Option<serde_json::Value> = DB.query("SELECT * FROM ONLY article LIMIT 1 FETCH revision").await.unwrap().take(0).unwrap();
let article = article_option.unwrap();
let title = article.get("revision").unwrap().get("title").unwrap();
