rust-mini-games VS autocxx

I personally like to make small video games, and I use the game as an excuse to learn some other technology by incorporating it. I've been doing this to learn Rust [0].

If you want to do something similar, I have a huge list of video game ideas you can pull from [1].

Related: If anyone is interested, I've been working on an ECS based mini-game framework in Rust [0] that runs with this idea. It has a 1200 hz simulation clock, 60 hz rendering clock, and 150 hz physics integrator (Euler). I've also posted some example mini-games that use it [1].

Tangentially related - if anyone is new to Rust and wants to see some simple mini text game examples, I've been working on a bunch [0]. It also includes some more complicated text games:

Asylum - Choose your own adventure style interactive narrative

Knights and Barbarians - Simple turned based strategy game

Legend of the Rusty Dragon - Simple adventure game inspired by Legend of the Red Dragon

Meanwhile, one of the best C++ sources which community mostly think of - Chromium - starting to experience with Rust. If i'm not mistaken using https://github.com/google/autocxx

There's bindgen, cxx and autocxx. Obviously not as convenient as C++ calling C++; the more you need to interoperate with C++ code the more it makes sense to just stay with C++.

If you want to reach the author for a correction, perhaps leave a comment on the Medium post or perhaps mention it on the autocxx PR I found this article from.

Rust and C++ are not directly interoperable, but you can try to use some fancy libraries if your C++ codebase is simple. Google is taking on this gargantuan task with autocxx. I believe it is related to their exploration efforts to bring Rust to Chrome.

I used autocxx in a recent project and was amazed at how easy it was to call into C++ -- Rust Analyzer was even able to provide completion hints.

Sure, they can improve C++ interop - and they have been - but that doesn't help them maintain the dozens of millions of lines of C++ they (Google, and others) currently have. Carbon is a pragmatic solution to the state of affairs in C++ that doesn't require them to rewrite all of their existing code to improve its maintainability.

The areas you mentioned (CLI, web services, low level systems programming) are not mutually exclusive. Doing a good job on one doesn't mean something else is affected.

The folks who worked on the most popular command line argument parser (https://docs.rs/clap/latest/clap/#example) made a positive contribution that didn't detract from any other use case.

Similarly, the folks working on improving Rust for web services will also make it better for systems programming. In a blog post published today (https://blog.rust-lang.org/inside-rust/2022/07/27/keyword-ge...), they discuss keyword generics, a feature that will be equally helpful for `async` code and `const` functions evaluated at compile time.

There is already some interoperability with C++ (http://cxx.rs) and ongoing research into automating this interoperability (https://github.com/google/autocxx, https://github.com/google/crubit). Feels like there's enough effort

That's not at all in Rust's bill, it needs an interaction layer to talk to C++. Efforts like cxx (and google's own autocxx) try to make this layer more automated and less painful, but the layer is still there, it still has a cost, and it doesn't erase the impedance mismatches between the languages.

Notably Google is also investing in autocxx to make C++/Rust bidirectional interoperation easier

Again, not really...? A lot of the proposed ABI changes (for C++ - I don't know what they're planning for Carbon) are trivial to automatically fix if you have source access. If you don't have source access, you "only" need to maintain the ABI at the boundaries between foreign code and your code, which is quite possible (especially after the success of autocxx and related projects in the Rust <-> C++ world)
