Instead of adding a `to_string` method on each definition struct, this commit implements `Display`. This shouldn't result in any breaking changes since the trait also exposes a method with the same name. I also tried to format the generated text here and there to make it more readable in the generate code base as well as in the generate text. Authored-by: Aviac <aviac@mailbox.org>  |
