Android now supports Rust programming language for developing the Linux kernel. We discuss some technical aspects of this work using a few simple examples. We believe Rust is ready to join C as a practical language for implementing the kernel. It can help us reduce the number of potential bugs and security vulnerabilities in privileged code while playing nicely with the core kernel and preserving its performance characteristics. The Linux kernel has over 30 million lines of code, so naturally our goal is not to convert it all to Rust but rather to allow new code to be written in Rust.”]
