- Support enums without explicit values
- Support string representation for enums

As a future improvement: what about using external crate for ident case conversion? |

Thanks for this contribution! Some nits to fix. Talking of which, could you kindly add emoji prefixes as per our contribution guidelines?
I'm not sure what you mean but I'd like to avoid adding a dep unless there is a compelling rationale presented. :) |

@katyo Hi there. Do you think you'll have time to finish this soon? No hurry, just a polite ping. :) |

@zeenix I'm a little bit busy lately, but I try fix this pr asap. |

Nice! I think you want to also update the docs.

Would be nice to document these additions in the macro docs.

SerializeDict and DeserializeDict already support these renaming attributes so I'm sure there is existing code you can use.

Of course, but currently dict_name_for_field expect syn::Field as an argument, not something like Literal or String. I would like to avoid modifying existing code which is not related to this PR.

It is related to this PR since there is no good reason to duplicate the code. AFAIK, it's a pretty trivial change so why not just do it? It will need to be renamed and moved to utils mod btw.

Just a gentle reminder, in hope that you're not super busy and can finish this PR. 🙏 |
