Rust is the future of systems programming, C is the new Assembly (Packt)

In my simple and exprimental project (https://github.com/lizhuohua/linux-kernel-module-rust), I implemented a simple driver for the Ethernet controller used on raspberry pi 3, based on Geofft's amazing project (https://github.com/fishinabarrel/linux-kernel-module-rust). And I found that the performance impact is actually negligible. However, I found the following problems:

1. Linux kernel doesn't guarantee API/ABI stability, so it's hard to design a universal Rust interface. At least it is almost impossible to make it work on all versions of Linux.
2. Many C language features have no corresponding Rust support. For example, it seems like impossible to construct a struct with bitfields.
But yes, I believe Rust is a promising language for kernel programming. Let's join forces to make this happen!
