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.
It is literally being pushed for its technical merits and traits.
Memory safe code with comparable performance in the kernel seems like an absolute no brainer.
Also if you watch the video all he’s asking for is consistent interfaces for the file systems. He’s not even trying to get them to use rust. And the guy starts screeching about how he’ll code however he wants.
Is it wrong to expect a consistent and well documented interface?
Pretty sure C is actually being pushed against its technical merits here.
It’s wrong to force it. Most choices in history don’t end up with the best one being used. Beta was better than VHS for example. Rust people are very bad at convincing others to try it, and objectively many people just don’t want to or don’t like it for various reasons.
Personally I highly dislike the syntax. People like familiar things, and to me it’s just too different from C++.
If anything I think Swift will be an easier sell when the speed and cross-platform issues are solved.
Beta was not better than VHS. Anybody could build a competing VHS machine, and it supported feature length films.
I would go so far as to say that yes most choices do end up with the best one being used, because people like nice things. Programmers just aren’t persuasive people in general, give it time.
