Good read: “Rust is the future of systems programming, C is the new Assembly”: Intel principal engineer, Josh Triplett I really couldn't see this before, but Rust is a replacement for C/C++, a clean replacement. Here is Redox OS : Redox is a Unix-like Operating System written in Rust, aiming to bring the innovations of Rust to a modern microkernel and full set of applications.

I'd like to see a Rust/Gecko/Quantum/SpiderMonkey implementation of Electron (replacing C++/Chromium).

Yaser Al-Najjar • Sep 3 '19

I really hope so 🙏

I'm preatty new to Rust, so the obvious question (for me) is: "why Rust over Golang in these cases"?

Nielvdw • Sep 4 '19 • Edited

Golang won't work for these cases. A garbage collector is like a layer on which the rest of the program runs. It's very unstable to bootstrap the GC in an OS kernel BEFORE the kernel runs. Aka you need a kernel first to run a GC, and with Golang you will need the GC first to run the kernel. Similar thing applies to many other systems, the extra GC layer is a continual pain point.

Yaser Al-Najjar • Sep 4 '19

Besides what @nielvandw and @buinauskas have already mentioned.

Before writing the post, I've done some research and found that Rust and Go are not competitors.

And I would also wanna add that Go is very very use-case-specific to Google-like products (scalable solutions made by tech gaints like Digital Ocean or Docker).
