The Google security blog has a detailed article on what a device driver written in Rust looks like. "That is, we use Rust's ownership discipline when interacting with C code by handing the C portion ownership of a Rust object, allowing it to call functions implemented in Rust, then eventually giving ownership back. So as long as the C code is correct, the lifetime of Rust file objects work seamlessly as well, with the compiler enforcing correct lifetime management on the Rust side, for example: open cannot return stack-allocated pointers or heap-allocated objects containing pointers to the stack, ioctl/read/write cannot free (or modify without synchronization) the contents of the object stored in filp->private_data, etc." ...
