rustboot

http://doc.rust-lang.org/book/unsafe.html#avoiding-the-stand... is the closest we have, currently. https://github.com/rust-lang/rust/wiki/Operating-system-deve... has a bunch of stuff, and https://github.com/charliesome/rustboot and its forks are examples that I know of.

> If so, will it be possible to call rust from, e.g., C code? I'd like to have an alternative to c/c++ for writing native extensions for interpreted languages. Yes. Technically it's already possible[0][1] but AFAIK it requires throwing out all (?) of the stdlib. rust-core[2] is an exploration of a runtime-less subset of the stdlib, which would ultimately be usable under a no_rt flag or something like that (at this point you have to disable the stdlib entirely and use rust-core instead) [0] https://github.com/mozilla/rust/issues/3608 [1] https://github.com/charliesome/rustboot [2] https://github.com/thestinger/rust-core

> Go. Go is a systems programming language Not those kinds of "systems". It is funny, it seems initially it was meant to be those kind of "systems", and then it pivoted as we like to say, to become a "distributed-server-network-backend systems" not "hardware-kernel-OS" kind of systems. And then creators kinds of winged it and remarked how "well, that's what we meant when we said systems". As for Rust, yeah, there are already a few projects trying to build a kernel or drivers in Rust. Here is one for example: https://github.com/charliesome/rustboot

Right now it's a fork of rustboot [1], a proof-of-concept repo for implementing a kernel in Rust. I'm working on extending rustboot [2] to support handling keyboard interrupts and to have a real print function. It's not remotely in a working state yet, but I'll definitely update my blog when I get keyboard interrupts working.

Rust[1] is aimed squarely at this use case. The GC and runtime are optional. A toy kernel[2] and Linux kernel module[3] have already been written in it. The language is young and still unstable, but it's being designed by veteran C++ programmers with the goal of using it for a safer, faster, more maintainable successor[4] to the browser engine in Firefox. Worth checking out! [1] http://www.rust-lang.org/ [2] https://github.com/charliesome/rustboot [3] http://thechangelog.com/rust-ko-a-minimal-linux-kernel-modul... [4] https://github.com/mozilla/servo

You can't write a kernel in Go because it has a mandatory runtime system and garbage collection. However, Mozilla's Rust language is similar in some ways, can work runtime-less, and a small demo kernel has been written in it: https://github.com/charliesome/rustboot
