How do you rewrite C/C++ projects to Rust?

Honestly there should be a filter for these types of articles. I’m not going to bother reading something another person did not even bother writing.

You don't. This days run your C/C++ code through AI and fix the issues it found. That gives you more in shorter time.

I rewrote my Haskell project in Rust.

memory usage dropped to half, execution speed is now 2x. Cross deployment is easy from silicon man to x64.

There are many low level optimizations available which i can exploit, compile is super fast for my project so development experience is better.

LOC dropped to half of the original.

Rust made life so much easier :)

Remembering times when JetBrains was about carefully crafted Java intellisense. And I don't think demand for such tools is gone.

1. Hop around a few rust communities and fill yourself up with full love of rust and hatred against c/c++.

2. Ignore any technical tradeoffs and considerations but solely lean on your guts and hypes on the Internet.

3. Ask Claude to rewrite the entire codebase to rust. Boom! Now you’re allowed to show off yourself on LinkedIn and HW as a super great rust engineer.

For Qt apps written in C++ I don't see how that could work yet.

Its kinda hard to understand the point somebody's making, when its articulated/made up by AI. Slop.

I've seen someone rewrite a wireguard proxy in rust for performance without realizing that it's just a daemon that interacts with the kernel to setup routing... But hey, at least the key generation is faster!

They didn't need the disclaimer for this to be obvious AI slop

Step 1. Start with a library that is a fat wrapper around a massive C++ library that does all the hard work

Step 2. Rewrite only the wrapper using already written tests.

Step 3. Get internet points because an LLM Rewrote it in Rust!
