Code:
fn main() {
println!("Hello, world!");
}

Funny syntax with the ! appended to the function.

Maybe it's for emphasis?

I do prefer that! It indicates it is a macro. I'm sure you'll have lots of fun going into that world.

Should the developer care about it being a macro or function? Seems like something just needless for me to remember.

Question: has anyone written an in-depth, "scientific" comparison of Rust and C++ at a level higher than "factional cheerleading" (no offence intended 
?
I found blogs like this.

In particular, precise details (without the handwaving) on why, how and when to use or not use Rust, C++.

Developers use Rust for general programming, web development, data science and video gaming, as well as for augmented reality (AR), virtual reality (VR) and blockchain projects.
OK, any other applications?

This is hard to come by it seems and is why I initially came to QN with the question. As far Iāve seen, itās mostly Rust advocates advocating for something new without really saying when/why itās better. And in that case, Iād just stick to C++.Question: has anyone written an in-depth, "scientific" comparison of Rust and C++ at a level higher than "factional cheerleading" (no offence intended

I spent the last 3 days doing Rust programming for a bit of relaxation (am almost an expert by now
, but being my age means I'm a fast learner). I plan to spend a few more days to suss out more features. It is just a C++20 lookalike; if you know C++20 (and you do) then it is a piece of cake.From Wiki
Rust is a multi-paradigm, general-purpose programming language that emphasizes performance, type safety, and concurrency. It enforces memory safetyāmeaning that all references point to valid memoryāwithout a garbage collector. To simultaneously enforce memory safety and prevent data races, its "borrow checker" tracks the object lifetime of all references in a program during compilation.
Rust was influenced by ideas from functional programming, including immutability, higher-order functions, and algebraic data types. It is popular for systems programming.[13][14][15]
This is true, more or less. But talk is cheap.

Not in my book. Inside Rust is a (not very useful) protean Actor model trying to get out. It is not OOP, GP, FP, really. More later.
Who would like me to write a small precise report on Rust?
Caveat: my opinion of 2024-5-6.

Good idea. This week I'm just kicking the tyres (like uchi komi) and then I can go to a small app, e.g. Black Scholes (call C++/C maths function from Rust). yes??
Rust does not have much OOP support ..
Our goal is eventually interop.

Would be downright excellent!
Also some of the more popular/common software design patterns used.

That seems fairly limiting, donāt you think? OOP is really useful in a lot of cases. Makes it seem like itād be difficult to build a trading system or pricing libraries, etc.
My day to day is probably 80% OOP and 20% functional.

Coming up, Sir!
A serious point I would like to addess is:
"If Rust is the answer, then what is the question?"
aka the right tools for the right job!

Random question: why is there a plethora of Actor "frameworks" in Rust?

Perhaps itās a language more suited for data processing relative to OOP?

It is probably a junior version of Erlang?
