Levy, Amit, Campbell, Bradford, Ghena, Branden, Pannuto, Pat, Dutta, Prabal, Levis, Philip.  2017.  The Case for Writing a Kernel in Rust. Proceedings of the 8th Asia-Pacific Workshop on Systems. :1:1–1:7.

An operating system kernel written in the Rust language would have extremely fine-grained isolation boundaries, have no memory leaks, and be safe from a wide range of security threats and memory bugs. Previous efforts towards this end concluded that writing a kernel requires changing Rust. This paper reaches a different conclusion, that no changes to Rust are needed and a kernel can be implemented with a very small amount of unsafe code. It describes how three sample kernel mechanisms–-DMA, USB, and buffer caches–-can be built using these abstractions.
