Worked on extending the FAISS library in the facebookresearch/faiss repository by developing new C API bindings for the IndexBinaryIVF class. This involved implementing C++ sources and headers to expose core functionality, including getter and setter accessors as well as essential methods such as merge_from and search_preassigned, making these features accessible from C. The work focused on enabling cross-language integration, allowing C-based projects to leverage FAISS’s binary indexing capabilities more easily. Utilizing skills in C API development, C++, and software engineering, this contribution broadened the usability of FAISS and supported smoother adoption in diverse production environments.
