It's hard to overstate how much I appreciate cargo, having worked with St. Dennis Ritchie's blessed language and Bjarne Stroustrup's monstrosity for years. Having a single, unified build tool and package manager (that the entire community actually uses) had me thinking that there had to be a catch.

[@ThePrimeTimeagen]

the exact same from me. its so incredible its hard to state how good it is

[@dealloc]

Abso-f'in-lutely. Not only is it the default tool for managing and building Rust projects, it is also very well made, even for manual build scripts. And the fact that you can easily extend it with user-land modules is the cherry on top. I've always dreaded having to install 10 different tools in order to configure, setup a project, targets and build pipelines when working with C and C++ code. Not to mention having to read, understand and modify someone's special syntax in each of those DSLs.

[@theherk]

Making something 'mut' does not automatically put it on the heap. In the example "let mut hello = "hi mom"; the string literal would be stored in the data segment of the binary and the size of the reference to it (hello) is known at compile time and can be stored on the stack.

As far as C goes - since it was among the first languages I learned, the memory allocation just felt relatively natural... You just learn how to manage memory.

[@stiliok]

@@loicmenard9006 So much relatable

[@edim108]

It's kinda like the issue with a native language. I never got why people say Polish is hard untill I learned another language and suddenly I started noticing some things. If the first language you learn and spend good time with was C then it's natural you don't see the issue with the memory allocation. It's when you spend time with other languages that you start understanding where these people are comming from, and where your language is better than theirs- good C code is still going to outperform Rust code. The only question is how valuable that little bit of performance is. If you're making a game engine then it's still probably worth it chacing that bit of performance...

[@jongeduard]

But he makes the Windows people scared. 😂 I hopes keeps a sharp eye at the unsubscribe count. 🤣 Actually I noticed Rust on Windows is pretty cool too! I started learning it on Arch Linux by the way, but on the Windows side there's a lot going as well, like the windows-rs projects that basically makes all old API stuff available to the programming language for which people formerly needed Visual C++. I really don't expect see Rust replace any DotNet stuff, but all the native stuff has definitely a serious chance. Would be great to see Rust and C# both dominate the future on the operating system.

I'm so glad my "hello world" main.exe can handle the most performance intensive system requirements.

[@first-thoughtgiver-of-will2456]

Nah you shouldn't look it as just free and malloc. It's really that everything on the heap is tied to a stack variable, so the heap just falls off the stack like stack variables in C. How you keep it alive is returning the stack variables (part of the reason it's so darn functional despite being system lang).

[@ThePrimeTimeagen]

yeah, this is a "more" correct view of it, which makes it super dooper, but its all about how much lying you do to learn. you start off by learning with max lies, then you slowly peel the onion

[@jongeduard]

Technically a lot can be compared to C++ and not just C. For everything that uses the heap, the Drop trait is implemented in Rust. This compares a lot to C++ classes and their destructors. It's basically the RAII code pattern, a concept also used by smart pointers, which both languages know as well. The idea is that you hang the memory management of the heap behind a stack based connection of a variable, which internally frees itself by going out of scope. In C++ you can also directly use new and delete, or even the good old malloc and free, and you can do tons of things wrong, even worse than in C, but as a good habit you follow the above the above code pattern as much as possible to avoid most problems.

[@theondono]

A lot of profesional C devs who think they know C, know relatively little of the actual language. I’ve met people who have been working as C devs for a decade, and have not read the C standard. They had no idea of what UB was, and a lot of times they’d blame the compiler for being buggy, when they’re the ones writing incorrect C and turning up optimizations hard. Heck, the people writing the standards are still learning how a lot of stuff works, things like pointer provenance are still in active development on C.

Wait a minute. malloc and free are far from simple to work with. Sure in the simple case that you malloc at the top of a short scope, do something with it then free it at the end of the scope it's easy to see what is going on. But: 1)When malloced objects are passed into or returned from functions it is not clear who is responsible for freeing them. That needs to be documented and the documentation needs to be read. 2) When malloced objects can live on outside the scope in which they are created and then perhaps passed around to other parts of the program it can be difficult to keep track of who is responsible for freeing them. Leading to memory leaks. 3) Like 2) but with threads thrown into the mix. But this is all tied up with use of pointers... 1) Perhaps one forgets to malloc an object, perhaps thinking it was done elsewhere in the program, then we have dereferencing a null or uninitialised pointer. 2) Perhaps one forgets an object has been freed, then we have use after free errors. One has to do a lot of bookkeeping, busy work, to keep track of all this in ones head. Or worse still the heads of a large team. Rust of course does all that tedious checking for you. What is not to like about that?

The biggest advantage and hurdle of Rust in my opinion. Advantage: Cargo exists.... and is already way better than python's PIP in my opinion. Like you need to manually create a virtual enviroment for your python projects and initialize it every time you work on it, meanwhile in Rust, all you need to do is type cargo new (Project name) and boom, you have a project folder with a virtual enviroment to which you can install the crates, AND a local repository all set up kinda automatically. (Also I never had any problems with cargo, but I did have a few with PIP) Disadvantage: Well, I know this is a beginner issue, and I am a beginner, so I'm sorry for this vent but LOOK AT THE INSANE AMOUNT OF SYNTAX THIS LANGUAGE HAVE, NOTHING MAKES SENSE WHAT THE HELL IS A LIFETIME? WHAT IS REALITY? WHAT IS GOING ON? (Still better than JavaScript tho, judging by my small experience with it, at least when I declare a float 32, I know it will always quack like a float freaking 32, and that the language won't try to add a string number to a float number.)

[@thekwoka4707]

Yeah pip is really awful. Even JS has a better environment/package management experience than pip/poetry/etc

The syntax is actually very good and compact once you learn more, like Option's "and_then", "map", if let, let else, etc.

when I was in college in the year 1999 I learned C, I knew already about the importance of habits, so every time that I made a stupid mistake I started a microhabit, to avoid the problem in the future, like closing a bracket immediately after opening, like if I typed an "if" I always did like `if(){}` and then fill in the blanks, because in that time, editors had no snippets yet, at least not the cheap BorlandC++ I shot myself in the foot with malloc/free and I took a strategy to separate "side effects" from the logic, but I didn't call it "side effects" I called it non CPU stuff so with malloc I made a function that was the context to create anything so it was like create((*void)dostuff(*void), size_t size) { void* data = malloc(size) dostuff(size) free(data) } and in dostuff I kept the lifecycle of whatever It was the data pointer referring to. and I had similar functions for FILE and other stuff, it was naive but it worked for my little projects, and this style of programing also led me to get interested in Common Lisp, the symbols in Lisp are like pointers, and not having types was "freeing" back in the early 2000s. I never got to work on full blown applications on C, except for a small embedded one for a bank for a card reader, but most of my job right outside college was Java.
