I just started learning Rust for a small project, and I found its "one clear path" model very appealing (I don't know if it is a formal goal, or if it's just a happy accident based on a smaller, more focused, community). It doesn't just apply to the package manager, but that's one of the first bits a beginner sees. Rust has a single, easy-to-find, "pretty good" answer for nearly every question a beginner asks, at least, it has, so far, for me. Cargo is that answer for packages and for building, and it's pretty good, and there's no debate about how to install or build Rust tools and libraries. I didn't really find that to be the case with Go, so even though Go is a simpler language, I have been more productive, much more quickly, in Rust. Within a couple of hours of starting my project (with only a cursory glance over the docs and tutorial) I had my project daemonized, had options parsing working, had system calls working, got logging working, etc. It was shocking how quickly I was up and running. I'd been hesitant to try Rust, because it looks big, and I'm kinda tired of big languages. I just don't have enough time/motivation to study a bunch of nuanced syntax and such; I'll never be a great C++ programmer, though I can muddle through and usually understand other people's C++ code. But, so far, Rust is proving to be one of the easier languages I've learned lately, partly due to the holy path being well-defined, and partly due to strong libraries that overlap my particular project perfectly (being a systems language built by very smart people, it has some very good systems libraries). I don't mean to imply Go is a hard language, it's not. I picked it up pretty quickly, too. Both are easier to learn than, say, JavaScript, because they're much smaller. But, I agree that there isn't a super clear path forward for a beginner with Go, including with installing and building. You just have to acquire more tribal knowledge to work in Go than in some other languages (but, much less than many others...older languages tend to have tons of that kind of thing).

Rust explicitly set out to have an excellent built-in package management solution. They tapped Yehuda Katz early on for this.

As a beginner, I really like rust. It has excellent package management, robust compiler messages, pattern matching... etc. But once I start trying to build non trivial data structures it becomes a nightmare. For example, doubly linked list, any sort of graph is extremely hard for me to build in rust but extremely easy to build in golang. I am still learning the full capability of rust, hopefully as I do more practice it gets easier. In the worst case I think I would still use it to build data pipelines since I really enjoyed the syntax and the safety check as long as I don't get into smart pointers or raw pointers. Also another annoying point is that some libraries use nightly.

    Of course, if you're comparing with Go, you need to compare apples to apples - since Go doesn't have ownership tracking, the equivalent Rust would necessarily have to be unsafe.
    - amelius 8y ago
      Yeah but Go has garbage collection. Rust's ownership model makes up for not having GC.

        I think that heap-allocating everything and using Rc<T> and Weak<T> would be a closer comparison to what Go does, than using idiomatic Rust with borrow-checked locals etc.

  I have to ask why you're not using a data structure from a library, though.

Rust easier to learn than JS lol... In Rust you have issues that will or will not overcome easily, nothing like that happen in Go. And seriously getting starting in Go takes less than an hour: - Install Go - Install VSCode + Go plugin - Start working

  I explicitly said above that Go is an easy language to learn. But, I found Rust easier. And, yes, I'm finding Rust easier to learn than JavaScript. Without question. It is a much, much, smaller and more cohesive language. It has some new concepts (features or techniques that I have never used in any other language), but so does modern JavaScript, and with JavaScript there's usually five ways to do it, and half of them are really poorly thought out. I don't dislike JavaScript. I'm not saying one shouldn't learn some; one definitely should. But, it's definitely going to be "some", for most people, because there's just too much of it to learn it all, unless you can devote yourself full-time to being a JavaScript expert. I aint got time for that. As I mentioned, I've built a (toy) project in Go. I've spent more time with it than Rust at this point. I know how it works, and what getting started looks like. And, though Go was pretty easy with few pain points, I've found Rust to be easier and to provide a more clear path for a beginner to follow, so far. Everyone is different, and we're all coming from different places. No one has exactly the same set of starting conditions for learning a new language as I do. For some, Go may be easier than Rust (I expected it would be, which is why I started with Go and avoided Rust for so long). For me, I am finding Rust easier. I haven't done much with it, but I was surprisingly productive surprisingly fast.

    I for one totally agree on rust being easier to learn than Javascript. I suspect it is because of the explicitness of rust vs the flexibility of javascript where you can do literally anything you wish without any sort of guard rails, then there's the ecosytem with like a gazillion tools in your build pipeline. I really admire front end devs because they do what I cannot, I guess i'm not as clever a programmer, I need the compiler to hold my hand , lead the way, and yell at me when I am going astray, rust does that for me , and when I'm done obiding by the rules, cargo is there to take over the rest of the process.
