If the spec contains default values why not make a constructor with all the missing fields or implement Default when all fields are covered?

For the first implementation I wanted to keep it simple, I don't exclude that in the future it will change.

Also lol:

Yep, I still need to figure out deep macro testing, for now I use the integration tests and cargo expand. This will absolutely change in the future :)

Thanks for the feedback!

It is also the bash approach, isn't it?!
