Hashmap rustlings help

[slim mango]

what are you specifically struggling with

[tender creek]

the whole question

i don't know what to write

is it safe to use an LLM or better to ask here?

[slim mango]

i mean if i wanted to learn i wouldnt use LLMs

[tender creek]

well thing is though, am not sure if the question makes sense or i do not know how to implement it at this point tbh

[slim mango]

i mean, not sure what's confusing about the question to me

[tender creek]

there is nothing wrong with the question. the problem is how can i write the code that this problem requires me to

more like i have no idea what to write

am thinking to make a for loop but nothing comes up after that

[slim mango]

isn't it just summing how many times a team goaled and didnt goal

[tender creek]

yeah, but like i got no idea how to write the code required

[slim mango]

have you at least read the docs for HashMap

[tender creek]

i did, but if i had to be specific, the one part am puzzled with is that am trying to make a for i in v loop to loop thru hashmap, then read scored goals and goals conceded then save both numbers in the team then return that

am i thinking straight??

[slim mango]

how would you loop the thru the hashmap that doesnt have any elements yet

i'd imagine that by "populate" the exercise is asking you to HashMap::insert to the map (or some other variation)

#[cfg(test)]
mod tests {
    use super::*;

    const RESULTS: &str = "England,France,4,2
France,Italy,3,1
Poland,Spain,2,0
Germany,England,2,1
England,Spain,1,0";

    #[test]
    fn build_scores() {
        let scores = build_scores_table(RESULTS);

        assert!(["England", "France", "Germany", "Italy", "Poland", "Spain"]
            .into_iter()
            .all(|team_name| scores.contains_key(team_name)));
    }

    #[test]
    fn validate_team_score_1() {
        let scores = build_scores_table(RESULTS);
        let team = scores.get("England").unwrap();
        assert_eq!(team.goals_scored, 6);
        assert_eq!(team.goals_conceded, 4);
    }

    #[test]
    fn validate_team_score_2() {
        let scores = build_scores_table(RESULTS);
        let team = scores.get("Spain").unwrap();
        assert_eq!(team.goals_scored, 0);
        assert_eq!(team.goals_conceded, 3);
    }
}

mb forgot to send the test function, this is the test function

[slim mango]

yea i'm reading it from the repo
