Contributed targeted improvements to the Parameters module in the eclipse-zenoh/zenoh repository, focusing on enhancing documentation clarity and expanding test coverage. Worked primarily with Rust, emphasizing precise handling of configuration separators and multi-value parameter keys. Updated module documentation to clarify separator usage and removed outdated references, reducing ambiguity for downstream users. Developed additional unit tests to cover edge cases, such as empty iterator scenarios, thereby strengthening reliability and reducing regression risk. Addressed minor code issues, including typo and escaping corrections, to improve maintainability. This work supported better onboarding and provided clearer guidance for developers integrating with the Parameters module.
