How do I collect the values of a HashMap into a vector?

Question

I can not find a way to collect the values of a HashMap into a Vec in the documentation. I have score_table: HashMap

Answer 1

If you don't need score_table anymore, you can transfer the ownership of Score values to all_scores by:

let all_scores: Vec = score_table.into_iter()
                                        .map(|(_id, score)| score)
                                        .collect();

This approach will be faster and consume less memory than the clone approach by @apetranzilla. It also supports any struct, not only structs that implement Clone.
