Provide traits for the given behavior

[DrSloth]

Hi,
it would be very useful if the derive macros where based on traits rather than implementing functions directly.
Is this out of scope? If yes i would probably start maintaining a fork which does that.

Thanks in advance

Not really, I originally just was not thinking that there could/should be a trait. This was rather an omission by me as I was just content with the duck typing working and moving on to other things.

I was thinking that a trait could be introduced without breaking anyone's codebase by:

1. add the trait
   • question is what to call the the "sub-crate" with the trait
   • overhauling derive-into-owned to be about the trait and not the proc macro would be quite the breaking change, if even possible
2. for one release generate trait and inherent methods
   • this should be possible even as a patch/minor release
3. for the next release drop inherent method generation
