Work Description: martin-g commented on PR #1631:
URL: https://github.com/apache/avro/pull/1631#issuecomment-1095569243
> While reading about procedure macros I found
https://crates.io/crates/darling. I have the feeling it may simplify our derive
functionality.
I've just pushed
https://github.com/apache/avro/pull/1631/commits/ff751500db3475170c8f10a946ced67088a648cc
- it uses Darling to parse the derive attributes.
I didn't manage to pass the `avro_attrs.doc` to the `quote!()` that
generates the TokenStream for the Schema :-/ `doc: #doc` didn't work.
Feel free to revert this commit if you don't like it for any reason!

> The tracking Issue for the Avro Derive Feature of the rust SDK.
> Proposal (copied from email):
> Have another rust crate that is importable as a feature on the main crate (in
> the same manner as serde derive), that will provide a derive proc_macro that
> implements a simple trait that returns the schema for the implementing type.
> Right now, schemas must be parsed from strings ( or read from files first),
> and closely coordinated with the associated struct. This makes sense for
> workflows that need to associate the same type across languages. For programs
> that are all within Rust, there are usability advantages of the proc_macro.
