error[E0382]: use of partially moved value: `question`
    --> src/main.rs:38:44

38  |         self.questions.insert(question.id, question);
    |                               -----------  ^^^^^^^^ value used here after partial move
    |                               |
    |                               value partially moved here
    |
    = note: partial move occurs because `question.id` has type `QuestionId`, which does not implement the `Copy` trait
