Write my first dedeserializer

[laticoda]

Hi, having read the serde doc, i am still not able to get it work.
here is my code:

#[derive(Debug, PartialEq, Serialize, Deserialize)]
struct Record {
    score_value: u32,
    player_name: String, //  does not implement `Copy`
    timestamp_fake: u32,
}

let yesterdayscore = Record { score_value: 1500, player_name: "yesterdayscore".to_string(), timestamp_fake: 7000 };
let myscore = Record { score_value: 800, player_name: "myscore".to_string(), timestamp_fake: 8000 };
let friendscore = Record { score_value: 800, player_name: "friendscore".to_string(), timestamp_fake: 9000 };

let mut allscores :Vec<&Record> = Vec::new();
allscores.push(&yesterdayscore);
allscores.push(&myscore);
allscores.push(&friendscore);

let serialized = serde_json::to_string(&allscores).unwrap();
println!("serialized = {}", serialized);
let deserialized: std::vec::Vec<&Record> = serde_json::from_str(&serialized).unwrap();

my goal is to save allscores in a txt file with json , and recover it
in a OOP style after derserialization.

You haven't made it clear what error you are getting. The serialisation portion works fine as far as I can see. The deserialisation part has the problem that you are trying to deserialise to a reference and serde doesn't know how to do that. Since there isn't really anything to borrow from, you probably just want to deserialise to owned data:

let deserialized: std::vec::Vec<Record> = serde_json::from_str(&serialized).unwrap();

(Playground)

I'm not sure what you mean by "OOP style", but it looks like that is what you want.
