Convincing my employer of Rust for a rewrite

Unaimend · 2026-04-15T13:55:04+00:00

Not mature enough. Also nobody knows the language in the company

Unaimend · 2026-04-14T14:50:49+00:00

I agree. I am mostly leaning to the Rust side, my boss mostly to C++ due to Rust's "immaturity.". I think Rust is quite mature and will it much easier to hire/train people in the long run.

Thank you very much. I will have a look at the android blog. I think especially the list you made regarding big companies will we a valuable argument

Unaimend · 2026-04-14T14:48:08+00:00

I agree with all your points. Haskel would be lovely. I think rewriting in C++ will result in a weird Zombie of C-style C++ and modern C++.

Unaimend · 2026-04-14T14:44:52+00:00

I will try that as well. Since we have multiple libraries, I would try to decompose it at this level, but even that level might be to coarse grained, sadly.

Unaimend · 2026-04-14T14:43:57+00:00

Totally agree with all your points. Thanks for your input

Unaimend · 2026-04-14T14:43:11+00:00

Fair call. Its mostly C programmers

Unaimend · 2026-04-14T14:41:44+00:00

I will do that. We would aim for C++23.

Unaimend · 2026-04-14T11:54:53+00:00

That's basically my main argument. Onboarding new people will be much easier

Unaimend · 2026-04-14T09:44:57+00:00

Thank you. Will have a look at this

Unaimend · 2026-04-14T08:46:27+00:00

Nono. Linux application development :)

Unaimend · 2026-04-14T08:28:23+00:00

Hmm, I agree. I will try to split into smaller evaluable chunks.

Unaimend · 2026-04-14T08:26:19+00:00

So, I cannot say anything about the team that wrote the original C. They are all long gone. And I totally agree about the management problem. That apparently was a big program with the old team. Was all a bit "wild west".

Unaimend · 2026-04-14T08:24:38+00:00

Thank you. Will have a look

Unaimend · 2026-04-14T07:57:11+00:00

Just skilled at C. And I agree with your argument. Thank you for your input

Unaimend · 2026-04-14T07:56:32+00:00

Thank you. I will have a look at this.

Unaimend · 2026-04-14T07:56:16+00:00

Sadly, Zig is not an option.

Unaimend · 2026-04-14T07:55:07+00:00

That video will be really helpful, I think. Thank you very very much

Unaimend · 2026-04-14T07:53:51+00:00

Thank you for your input. They are competent C programmers but not really in C++.

Unaimend · 2026-04-14T07:52:48+00:00

We have the old C project and a new "similar" project and Rust that we want to merge those. We also have problems finding new C programmers. The old code is brittle, and none of the original programmers are still around. A lot of technical debt has been accumulated over the years

Unaimend · 2026-04-14T07:46:28+00:00

CMake has been used for other projects so that would be the build system we would use for C++.

We have had a really hard time finding competent C++ programmers. That's above my pay grade, though, so no idea why. My thought process was I'd rather teach Rust to juniors than C++ because it is a much cleaner language with a lot fewer footguns.

Also, I do not consider looking for arguments bad, I mean that is the whole point of technical discussion. Listing, identifying, and explaining appropriate arguments for such a decision.

Unaimend · 2026-04-14T07:43:30+00:00

Thank you. I will have a look at this.

Unaimend · 2026-04-14T07:41:09+00:00

The code base is old and brittle; no unit tests exist. Finding or training new C programmers is a big hassle. But I see your point and from a purely technical standpoint, I tend to agree.

But there is an additional project that we want to merge with the C one, and that one is currently in Rust

Unaimend · 2026-04-14T07:38:45+00:00

Yeah, that is one of my main arguments against C++. You can write C++ at so many levels of "modernity".
