Worked on modernizing the tracing API in the dora-rs/dora repository by removing the deprecated with_jaeger_tracing method and encouraging adoption of the updated with_otlp_tracing approach. Focused on API design and backend development using Rust, the work involved a careful deprecation-driven refactor to streamline the tracing module and align it with OTLP standards. This change reduced the API surface, simplified future maintenance, and improved compatibility with observability best practices. The update enabled smoother integration paths for future tracing enhancements while maintaining backward compatibility, demonstrating a methodical approach to Rust crate maintenance and thoughtful consideration of long-term codebase health.
