Google says replacing C/C++ in firmware with Rust is easy (www.theregister.com)

Google recently rewrote the firmware for protected virtual machines in its Android Virtualization Framework using the Rust programming language and wants you to do the same, assuming you deal with firmware.

In a write-up on Thursday, Android engineers Ivan Lozano and Dominik Maier dig into the technical details of replacing legacy C and C++ code with Rust.

"You'll see how easy it is to boost security with drop-in Rust replacements, and we'll even demonstrate how the Rust toolchain can handle specialized bare-metal targets," said Lozano and Maier.

Easy is not a term commonly heard with regard to a programming language known for its steep learning curve.

Nor is it easy to get C and C++ developers to see the world with Rust-tinted lenses. Just last week, one of the maintainers of the Rust for Linux project - created to work Rust code into the C-based Linux kernel - stepped down, citing resistance from Linux kernel developers.

"Here's the thing, you're not going to force all of us to learn Rust," said a Linux kernel contributor during a lively discussion earlier this year at a conference.

I would add to the downside that it's not the best programming language for game development, etc. There was some blog post about how troublesome is it to develop games using Rust due to some of the features that are good in other areas, like the whole concept of "immutable by default".

I can also recommend D, if you want to deal with different issues, like the D Language Foundation fearing of change due to not wanting to deal with division from a new and incompatible version yet again, the GC being both a blessing and curse, if you want to go without a (tracing) GC you'll need to go with a custom runtime that potentially missing many of its features, the attribute hell, etc.

The guy doesn't know what he is talking about.

When someone is stating something like "best programming language", you immediately know he's fuck all and he's trying to sell you something...
