To Help Rust/C++ Interoperability, Google Gives Rust Foundation $1M

An anonymous Slashdot reader shared this report from SiliconANGLE:The Rust Foundation, which supports the development of the popular open-source Rust programming language... shared that Google LLC had made a $1 million contribution specifically earmarked for a C++/Rust interoperability effort known as the "Interop Initiative." The initiative aims to foster seamless integration between Rust and the widely used C++ programming language, addressing one of the significant barriers to Rust's adoption in legacy systems entrenched in C++ code. Rust has the ability to prevent common memory errors that plague C++ programs and offers a path toward more secure and reliable software systems. However, transitioning from C++ to Rust presents notable challenges, particularly for organizations with extensive C++ codebases. The Interop Initiative seeks to mitigate these challenges by facilitating smoother transitions and enabling organizations to leverage Rust's advantages without completely overhauling their existing systems. As part of the initiative, the Rust Foundation will collaborate closely with the Rust Project Leadership Council, stakeholders and member organizations to develop a comprehensive scope of work. The collaborative effort will focus on enhancing build system integration, exploring artificial intelligence-assisted code conversion techniques and expanding upon existing interoperability frameworks. By addressing these strategic areas, the initiative aims to accelerate the adoption of Rust across the software industry and hence contribute to advancing memory safety and reducing the prevalence of software vulnerabilities. A post on Google's security blog says they're excited to collaborate "to ensure that any additions made are suitable and address the challenges of Rust adoption that projects using C++ face. Improving memory safety across the software industry is one of the key technology challenges of our time, and we invite others across the community and industry to join us in working together to secure the open source ecosystem for everyone." The blog post also includes this quote from Google's VP of engineering, Android security and privacy. "Based on historical vulnerability density statistics, Rust has proactively prevented hundreds of vulnerabilities from impacting the Android ecosystem. This investment aims to expand the adoption of Rust across various components of the platform." The Register adds:Lars Bergstrom, director of Android platform tools and libraries and chair of the Rust Foundation Board, announced the grant and said that the funding will "improve the ability of Rust code to interoperate with existing legacy C++ codebases.... Integrating Rust today is possible where there is a fallback C API, but for high-performance and high-fidelity interoperability, improving the ability to work directly with C++ code is the single biggest initiative that will further the ability to adopt Rust...." According to Bergstrom, Google's most significant increase in the use of Rust has occurred in Android, where interoperability started receiving attention in 2021, although Rust is also being deployed elsewhere.... Bergstrom said that as of mid-2023, Google had more than 1,000 developers who had committed Rust code, adding that the ad giant recently released the training material it uses. "We also have a team working on building out interoperability," he added. "We hope that this team's work on addressing challenges specific to Google's codebases will complement the industry-wide investments from this new grant we've provided to the Rust Foundation." Google's grant matches a $1 million grant last November from Microsoft, which also committed $10 million in internal investment to make Rust a "first-class language in our engineering systems." The Google-bucks are expected to fund further interoperability efforts, along the lines of KDAB's bidirectional Rust and C++ bindings with Qt.
