Developed foundational Rust bindings for the ECMWF GribJump C++ library, enabling efficient data extraction from GRIB files within the ecmwf/gribjump repository. Focused on establishing a robust Rust-C++ binding layer using FFI techniques, the work provided initial support for parsing and integrating GRIB data into Rust-based analytics pipelines. This effort laid the groundwork for future enhancements by creating an extensible and traceable interface between Rust and C++. The implementation emphasized performance and maintainability, ensuring that downstream data processing tasks could leverage the new Rust-based data path. Core technologies included C++, Rust, and data extraction through foreign function interfaces.
