Enum Question 

#[non_exhaustive]
pub enum Question {
    Noul(Noul),
    Choice(Choice),
    Score(Score),
}

One typed question: a Noul, a Choice or a Score, told apart on the wire by its type field.

Each of the three converts with into(), which Questions::with and Questions::insert do for you. The enum is #[non_exhaustive]: System One may gain question types.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Noul(Noul)

A yes/no question, answered by a NoulAnswer.

Choice(Choice)

One option out of a set, answered by a ChoiceAnswer.

Score(Score)

A rating on an ordered scale, answered by a ScoreAnswer.
