[@khai96x]

Honestly, I don't think Rust could have grown as big as it is now if it have stayed true to its original vision that is a garbage collected high-level programming language. The main value proposition of Rust that attracts all kinds of developer is its ability to provide high-level programming features, memory safety, and low-level performance at the same time. You don't ever see people rewrite their C++ program in Go, but the option is tempting in Rust.

[@sharanchakradhar]

Yet, Many companies ask for 5+ years of exp.. First of all, the jobs are very less and companies adoption is minimal for some reason. Been trying to find a job in rust with 0 years exp is very hard especially in Australia.

If you start to leaning into generative AI, us as the audience cannot know to what extent it is being used (such as possibly for your script) which is going to make me think, you don't have anything good or original to say that hasn't already been said. Because as we all know, generative AI does not actually create new things, it just rehashes and regurgitates training data. Maybe I'm in the minority here, but feedback is feedback and I only give it when I actually care about a channel.

[@not_herobrine3752]

It has its place in making writing mission critical software easier, but the hype train does have a tendency to push the language into suboptimal environments and then claim it's the best tool for said job, when clearly less painful tools exist for the job As an example, writing gameplay in Rust is tedious compared to C/C#/C++ because video games involve modifying and iterating over lots of mutable state, and modelling this in Rust is much less ergonomic than other languages that will let you mutate state like clay

@@not_herobrine3752 It took me three months to get the language down and a few more to make anything productive. It took so little time because of the rust book that is freely available . Now it is the same for c and c++ but there library system and the way of using files is the issue for me. I am always looking for easy of use and less configuration over head/complexity. Rust reminds me of c++, c# or java but with a simple configuration system. It does not require you to configure a pointer like in c , setup your files, compile them to classes then use them in another file like java, or download an external system to add libraries and compile your code nor does it require you to learn a whole other programming language like with cmake (does not include meson , ninja, make). Most of the stuff listed comes with the package with rust.

[@abacaabaca8131]

I always love rust when it says it can stop memory leak from the very beginning. I learn most of of programming learning from KZbin and having heard that from an experience programmer saying "This program may have a memory leak". So, I become afraid of C++ and start learning rust. Although it is not perfect, I begin to start loving rust. Lately, I re-visited my rust project again, and to my surprise, when compiling as release mode rather than debug the binary size is shrinked down by up to 99%. In my case the debug binary size is 800,000 kb which I don't like. For release binary, only 8,000kb.

[@FlorianZier]

Put this in your Cargo.toml to optimize for speed and still remove as much as possible: (opt-level: "z" to optimize for size) ``` [profile.release] #debug = true strip = "debuginfo" codegen-units = 1 opt-level = 3 lto = "fat" panic = "abort" ``` Take this as starting point, but also check the documentation to see what these settings stand for.

There are many things I love about Rust: The way I can add crates/dependancies, ownership, borrowing, the scope that keeps and drops codes to ensure safety (expiration date literally).

[@hobis0b]

But these days, I'm thinking about Rust's shortcomings. It's good that it's different from the existing C++ and that it's different. It is also good to use abbreviations such as fn, mut, vec, and Rc. However, if you decide to break away from the grammar of the C-based language, Reference operators (&) and pointer operators (*) are also used as new symbols or keywords. I think it would have been good if they had changed it. Personally, I think the easiest language to code in is Ruby rather than Python. Ruby does not make keyboard typing difficult by pressing the shift key. Since using a lot of symbols does not contribute to readability these days, it is regrettable that it would have been better if a newer approach had been taken in a system language that is about to change significantly.

[@logicaestrex2278]

i personally hate the abbreviations in rust but i agree on your other points. not a big fan of rust, and one of the reasons why is because the same symbols mean different things, and i really didnt like the lack of freedom and (imo) ugly syntax. im curious though, what are some examples of a more ruby like syntax in rust? that sounds nice

[@lukeskywalker2116]

It’s only memory safe if you don’t have to interact with external libraries or code and the compiler has zero bugs. When was the last time you wrote code with no external references of any kind and no dependency on libraries? We were solving these issues in the 80’s with Ada, but its marketing wasn’t sexy enough. However,it’s a significant improvement over C++.

Rust is not going anywhere. It is not good for gaming development, where C++ is king, and it will continue to be. It is not good for distributed system, where BEAM (Erlang and Elixir) is a much better choice. As for kernel development, yeah, maybe, but Zig has a better support for C, and so it is probably more suitable to develop drivers or kernel modules in general. I am not saying that Rust is bad, but I don't see Rust "dominate" anywhere. It has its own limitations, and it is not much better than modern C++. The borrow checker is cool, but it also forces you to write a program in the way the compiler wants, not in the way you would like, right or wrong your way it is.

[@arson5304]

why is it not good for game development lol, take a look at the bevy project and the whole ecosystem behind it. both cloudflare and discord beg to differ on distributed systems, they have many blog posts about load balancers and services with so many pros with the only sacrifice being time. your third point is only held together by the fact that all current kernels are written in c; inevitably technology will advance and c will become obsolete in this space. i'll die on the hill of rust being better than modern c++ any day; it comes with all of the abstraction capabilities and more, without the decades of baggage from terrible and redundant design decisions (std::expected & exception handling, c++20 concepts & template metaprogramming, operator overloading, 5 different constructor types, inconsistent behavior among the different compilers, i could go on and on) rust understands that sometimes you need to bend the compiler to your will given its conservative nature, which is what unsafe rust is for. you tell the compiler that you know what you're doing and it will let you do things like dereference raw pointers, mutate static variables, and all that mess.

It's suitable for kernel and driver programming because of the memory safety hence why we're seeing more and more drivers being written in Rust + Rust in both Linux and NT. It's also becoming huge in high performance web services. The borrow checker also doesn't force you to write a certain way, it just forces you to write code that isn't dangerous. There is a world of difference there.

[@FlorianZier]

It also has it's strengths in drivers, embedded and many safety related projects. And don't forget WASM, sometimes it's way easier to build something for Win/Linux/Mac/Web at the same time, because of wasm-bindgen and cargo. If someone can see the references as "exclusive mutable borrows" (one at a time) and "shared immutable borrows" it becomes so much easier to deal with the language rules. The trick is not to fight the borrow checker and make use of traits and available features. Dealing with lifetimes can be the hard part though, so it's better to avoid it unless absolutely needed. But that's more a problem of some libraries and if you really need absolute speed, otherwise not worth most of the time as long as you can avoid it.
