Worked on the Near-One/mpc repository to refactor the indexing module by integrating IndexerStats directly into the IndexerState struct. This change centralized the management of indexing metrics, improving encapsulation and reducing the risk of fragmented or inconsistent statistics. The approach focused on enhancing maintainability and laying groundwork for future metric enhancements, all while minimizing impact on the external API. The work was implemented in Rust and emphasized system design and refactoring best practices. By consolidating metric initialization and usage, the developer delivered a cleaner, safer codebase that supports more robust metric tracking within the indexing system for future development.
