Examples

use std::collections::HashMap;
use serde_json::value::Value;
use chewdata::updater::tera_helpers::function::object::extract;

let from = serde_json::from_str::<Value>(r#"[{"field1_1":{"field1_2":"value1_1"}},{"field2_1":{"field2_2":"value2_1"}}]"#).unwrap();
let mut args = HashMap::new();
args.insert("from".to_string(), from);
args.insert("attributes".to_string(), Value::Array(vec![Value::String("field1_1.field1_2".to_string())]));

let result = extract(&args);
assert!(result.is_ok());
assert_eq!(
    serde_json::from_str::<Value>(r#"[{"field1_1":{"field1_2":"value1_1"}}]"#).unwrap(),
    result.unwrap()
);
