We developed a Rust language binding for LibreOffice's Universal Network Objects (UNO) API. This work allows Rust developers to write LibreOffice extensions, automation scripts, and document processing applications while maintaining Rust's memory safety principles.

The LibreOffice Rust UNO Bindings project delivers a production-ready, type-safe Rust language binding for LibreOffice's Universal Network Objects (UNO) API, featuring automatic code generation for all UNO types through an innovative three-layer FFI architecture. We successfully bridged Rust's memory safety guarantees with LibreOffice's complex C++ UNO system, enabling direct runtime integration and safe office automation capabilities. This technical report explores our architectural decisions, implementation challenges, and lessons learned that can benefit developers working on similar cross-language integration projects.
We built this project to enable Rust developers to write scripts, extensions, and business logic for LibreOffice using Rust's safety and performance advantages.
This binding system allows developers to create LibreOffice scripts i
This report details my contributions to enabling master page copying in LibreOffice Impress, addressing a 13-year-old bug (Bug 45617) that prevented users from duplicating master page templates. My work, delivered through two Gerrit patches (Change 179832 and Change 182206), was integrated into LibreOffice 25.8.0, released in 2025. The changes involved refactoring a complex codebase and implementing robust master page copying functionality, significantly improving Impress’s usability for creating presentation templates.
