Improving Interoperability Between Rust and C++

Back in 2021, we announced that Google was joining the Rust Foundation. At the time, Rust was already in wide use across Android and other Google products. Our announcement emphasized our commitment to improving the security reviews of Rust code and its interoperability with C++ code. Rust is one of the strongest tools we have to address memory safety security issues. Since that announcement, industry leaders and government agencies have echoed our sentiment.

We are delighted to announce that Google has provided a grant of $1 million to the Rust Foundation to support efforts that will improve the ability of Rust code to interoperate with existing legacy C++ codebases. We’re also furthering our existing commitment to the open-source Rust community by aggregating and publishing audits for Rust crates that we use in open-source Google projects. These contributions, along with our previous interoperability contributions, have us excited about the future of Rust.

“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.” – Dave Kleidermacher, Google Vice President of Engineering, Android Security & Privacy

While Google has seen the most significant growth in the use of Rust in Android, we’re continuing to grow its use across more applications, including clients and server hardware.

“While Rust may not be suitable for all product applications, prioritizing seamless interoperability with C++ will accelerate wider community adoption, thereby aligning with the industry goals of improving memory safety.” – Royal Hansen, Google Vice President of Safety & Security
