Selective withTransientEmpty

[beneyal]

Hello,

Is there a way I can choose which case class fields I want to appear in the resulting JSON as empty containers and which ones I don't want to appear at all, preferably without changing my case class field definitions? Much of this library is still pretty magical to me, so I don't know if I'm missing something obvious 😅

Thank you for your time and for the amazing library!

@beneyal Thanks for your feedback!

Unfortunately, it is not possible to do on the field level. It would be a good feature to add corresponding compile-time annotations for remaining derivation configuration options that are not supported on that level yet.

For now you can try a couple of workaround based on types:

• define some separate type or a wrapper (as example that one which extends AnyVal) and create a custom codec with different configuration for it
• wrap optional fields into Option type and use a separated configuration withTransientNone for them.

Thanks for the light-speed response! I will definitely try those options!
