Rust For Linux
The purpose of Rust is to write performant software while shifting cost from runtime (in the case of garbage collected programming language like Go) and future headaches (in the form of memory mismanagement and undefined behavior from C and C++) to when the code is written. Writing safe programs is particularly important for Kernel code, as bugs and vulnerabilities affect the whole system. Rust – through its abstractions, and borrow checker – helps developers achieve this over using C. I love C. I love being close to the hardware: I would not be writing about this I didn't. But the ability for Rust to encode semantic information about the type system has led me to embrace it.
Rust for Linux is not only an interesting programming language problem – it is also a management problem. The Linux kernel is gigantic, and many developers may have different opinions on Rust, how it should be integrated, or how programming interfaces should be encoded in its type system. This may be unpleasant for many people, but the contention is a great way to learn about the Linux kernel.
