Developed advanced AvroSchema renaming functionality for the ankane/avro-rs repository, focusing on improving API ergonomics and maintaining backward compatibility. Leveraged Rust macros and schema definition techniques to introduce per-variant enum renaming through a VariantOptions struct, as well as a global rename_all attribute powered by a dedicated case-matching module. Comprehensive tests were written to ensure the reliability of the new renaming features and to safeguard against regressions. The work emphasized consistent naming conventions across fields and variants, enhancing both developer experience and documentation alignment while expanding the flexibility of code generation workflows within the Avro ecosystem.
