Struct Questions 

pub struct Questions(/* private fields */);

The questions for one call, each under an id. Answers come back under the same ids.

Ids are never sent to the model as meaning, so each question has to carry its own. Questions in one call share one read of the state and are answered in parallel, without seeing each other’s answers.

use typesafe::{Choice, Noul, Questions};

let questions = Questions::new()
    .ask("billing", Noul::new("Is this ticket about billing?"))
    .ask("tone", Choice::new("What is the customer's tone?").options(["calm", "angry"]));
assert_eq!(questions.len(), 2);
