i fully agree with this take. i've spent 5 years writing go backends and 3 years writing rust backends. i was a huge proponent of rust for everything up til last year. even tho i am up to speed on how it works, it's so slow to write and a way heavier mental model than go. another thing you didn't mention is it takes literal seconds to "compile" and run a golang script on any target. rust projects can take multiple minutes to compile and more often than golang, cross compiling will be an issue

[@ruanpingshan]

I have a question as someone who used to do backend in C# 10 years ago: what exactly is the benefit of using Go over C# and Java? Does it really make that big a difference if you compile to native instead of using .NET's JIT? And is the backend ecosystem in Go mature enough to handle everything that you'd need for backend like HTTP, URL rewrite, load balancing, database connectivity etc. ?

Well Said. Even for those one offs, code tends to grow legs. Even if it has clear requirements that 'shouldn't change' (Yeah I've heard that before!) I've had one line bash scripts we thought would just be a one time, run and done instance turn into several thousand lines of Go code with options, subcommands.

You convinced me to get into go and learn a compiled language with your comparison videos a year or few years back i felt like i was on the wrong boat after the hype built around rust.

[@boccobadz]

@@katrinabryce I don't know anything about Polars (maybe I'll give it a try after reading more about it) but back in the day we used PySpark to work with geospatial data (telco business, pandemic times) and were reading/transforming/modelling/outputting dataset (about 3 billion unique rows big) a day in less than 60 minutes before any optimizations. With some clever hadoop opt it was less than 40 minutes. The resulting dataset was 5k big. Developing and testing the whole pipeline (pulling data from all other place with hadoop->logging->pyspark->numpy->some graphs and clustering->logging->back to hadoop / flat files for reporting to government via ftp->visualization & reporting to higher-ups) took me about 2 weeks, I've written it in June 2020 and it's still running in production (on a cluster, and I wish concurrency in python was as easy as it's in go) without any hiccups to this day (even though I left that company over 2 years ago, good code for tracking people and their behavioural patterns (eg which fastfood do you like) still has its business value). Even though it's mostly python and not "the safest" rust. Most of the time people assume the language is slow and therefore bad when, more often than not it's not the case - they can't write good performance code / identify bottlenecks - either because of lack of knowledge of algos, or because of lack of understanding of what's going on under the hood (eg looping over whole pandas dataframe or apply lambda instead of pure vectorization/numba jit). Expand your horizons, try as many approaches as possible for semi-serious stuff (world doesn't need another todo app), pick the tool you're the most comfortable with and learn it well. Only then you will be truly blazingly fast 😂

Just building a simple cli tool to export data from an API, transform it, and then put it into an excel spreadsheet was way more work than it should have been

[@raiguard]

I spent eight months learning rust and trying to write my project with it. My project includes json parsing, filesystem interactions, decoding compressed binary data, and making web requests. It was a battle every step of the way. I finally gave up and tried go, and within two weeks I had the project up to feature parity with the Rust version. The difference in productivity for me is nuts. I like a lot about Rust, but Go is way easier to use. And I agree that Go desparately needs tagged unions.

[@georgehelyar]

This isn't quite a fair comparison because the second time you write something it will always be much faster to write Also rust probably does have more of a learning curve but the real question is what are they like after you've used each of them for quite a while

[@dealloc]

I did all of these things over like 5 months as I learned Rust and I found it to be such a relief. To be fair, I did also write a ton of parsers, encoders and decoders in other languages, so I had an idea. But I did struggle at first too, but I followed my own principles for learning a new language: - Clone if I need to. I am not learning lifetimes at this point. It is a battle of itself that I would somewhat overcome later. - Don't think about the Rustcean way to do things at first. Think about how I'd do it with current experience as well as knowledge I gathered from reading docs (e.g. examples). This is the way I learned about iterators, and made things a lot easier after learning just a tiny subset of the API. - Read the docs and learn the built-in APIs before learning libraries. I ended up writing much more code with std libraries than if I had used libraries, because those provide lower level APIs, but.I also learned their limits in respect to time spent. 4) Switch the implementation with a library. I initially went with logos before I discovered nom for text parsing, and bytes before I discovered deku for bit-level binary decoding/encoding. 5) Read some open source code of things in similar vein. Search for things that are similar to what I am trying to solve and see how others are doing it. I learned a ton of libraries and other APIs from this, too. Like for storing some static state I found lazy_static immensely useful, before moving over to once_cell. Also I recommend watching Crust of Rust by Jon Gjengset and his other videos. He's extremely knowledgable in Rust, working for AWS building the Rust infra there, and is a really good explainer of things.

[@raiguard]

@@georgehelyar That's a fair point, the lessons learned the first time around undoubtedly skewed the results. However, I would estimate that 90% of the time taken in the rust version was rust-related, as the business logic of the app is fairly straightforward.

[@danielchettiar5670]

And I think you didn't need any external packages on Go right?

[@LucasOe]

My first Rust program was a tool that required a lot of Json parsing and file system interaction and it honestly went great. Of course I still had to refactor a lot because I didn't have a good idea on how to structure my code, but that would have been the case in any new language for me. Serializing and Deserializing using Serde was really easy, only thing I was missing is internally/adjacently tagged enums.

[@andythedishwasher1117]

Tbh, there's just something about typing out "if err != nil" that makes me sip my coffee and be like "yeah. I'm a Go developer."

[@ForeverZer0]

I enjoy writing Go, but my biggest "wish-list" item, even more than enums or ternary operators, is that they would sprinkle in some syntatic sugar for error handling. A basic "try" keyword that would executing a command, and automatically return an error if the last argument was a non-nil error type and the function returned an error as its last return value. That alone would cover a ton of scenarios.

[@danielmajer1648]

I am staying on Go's side. I enjoy writing it at work, simple and easy and has the performance. I don't break my head while writing it.

I was looking into Go and Rust for an API overhaul we're doing at work. Go (with Fiber) seemed like a way better option than Rust (with tokio/actix etc). I've had a pleasant experience so far with Go and learning its quirks. I'm a little disappointed because i wanted to have an excuse to use Rust, but ultimately I think its the best decision... and its way better than our current PHP solution.

[@connorlatham9578]

[@GaneshR-2023]

I'm not a professional programmer and lots of what he says goes over my head. I've never used rust. But I have dabbled with Excel VBA macros, awk etc for text file manipulation involving dictionaries / maps. When a requirement came up where executable made more sense, better logging and DB access was involved, I tried out go. With zero time spent on language basics or concepts, I could write utility programs that are in regular daily use for couple of years now with no issues. It works. They deal with loading text files dumped in a certain folder to database with some manipulation and error checking etc. Or format conversion with mapping based on maps. I wanted to install rust but realised in windows, it requires much bigger download. I still want to learn it as it seems to be replacing C in Linux. Now that's not easy so it sure has something going for it!

[@zenedge7599]

With Rust, ive come to the point where if i need to summon the dreaded 'a on a type, I just make it a raw pointer instead. Easy to work with, let RAII handle it. (if needed, most the time you use a pointer in place of reference you wouldnt need RAII anyway, just a light wrapper around unsafe {})

[@mohsinhijazee2008]

I rarely comment on KZbin videos but this is really really pragmatic take. I mean, I'm too old for that language choice so go is too good, too minimal to avoid over engineering. Rust when inputs and outputs can be chained together. Thanks for the clarity.

[@oidualx]

Wow, I generally agree with most of the thing you say, but in this case I don't fully get your points. Any single time I was forced in Rust to think harder than any other language about a concept, it was almost always the compiler saving me from a runtime error. And very much explicitly so, it points you exactly at the problem and how to think about it. Immutability by default (but at the same time the possibility to explicitly opt in to mutability), Option, Result, pattern matching, iterators, error handling, are concept that once ingrained in the everyday work are deeply missed when you return to a language that doesn't support them. About the web server part, I don't get it. I would understand if you had to design it from scratch, but there are phenomenal libraries in cargo that make creating a web server a child's play. At that point is it really that much more complicated than doing so in other languages?

[@ThePrimeTimeagen]

ok, i can "see" your side, but at my current experience i just don't think its quite right

[@ericng8807]

(Go vs Rust by Michael Mullin) kzbin.info/www/bejne/e16XaImCrLKMlbc This video might shed some light on Prime's statement "Most semi-experienced Rust devs will write less performant code than a Golang dev". Alot of your points are about Rusts safety features via the type system. But that safety, means that Rust will not make any assumptions on how certain pieces of data will be used. An example given in the video i linked was about strings. The naive way to iterate through a string in Rust is much less performant than the way golang handles strings by default. So unless you know how certain pieces of data are represented at a rlly low level, languages with a smart runtime may be faster than the Rust counterpart. Ofc if you're very into how computers work, down to details that most people don't explore, Rust will be faster

[@nordgaren2358]

I had to write C++ the other day, and I just started making everything const by default. 😆

[@lucasldossantos]

💯 Go is a big step backwards in terms of promoting good practices like immutability, writing non-defensive code with good error handling and null safety. It's indeed easy to write code in Go, but it's also easy to write BAD code in Go, because the simplicity of the language comes with a cost. I've seen code in Go that performs really well, but was buggy and unmaintainable because it had so much hidden complexity caused by data mutation and no proper error handling.

[@c0zn1c]

Which would be better for creating audio processing apps? Like a DAW with multi threaded parallel support and WAV generating functions? Mobile apps and VSTs. DSPs basically. I also want it to do AD/DA conversions. Which has a better library and support for this? I'm a total noob so I'm leaning towards Go, because of the ease of entry, but Rust seems like it would have less latency with the less memory usage and safety. How does Golang compare in that regard? I need minimal audio processing latency with control over 32-bit float. Maybe even 64-bit for desktop. Tl;dr: which is better for high quality, low latency audio processing apps, and has VST3 library support?

[@michaelhart8928]

I think what you’re getting at is that Rust is amazing when the problem scope is well defined and understood. An LSP is a great example as are tools and definitely some systems programming stuff. Where Go shines is where the scope is not defined. When you’re starting up a new company, requirements change substantially. Same with web servers. It’s the language that has almost all of the performance, but the guarantee that you can work out the next batch of requirements without substantially changing your code base. Both languages can do either situation but given my experience I feel the same way.

[@StefanoV827]

Can we have a comparison between Dart and Go as a backend? Since i like dart the most but i dont get why nobody use it also for backend since isolate management and sound null safety are so amazing.

[@Felix-un7yp]

My biggest concern about Rust is a slow compilation time, although I am not sure if this is really an issue in practice. Anyways, for most servers I would agree to prefer Go.

FWIW, in Rust you can pack any chonkier struct into an Rc / Arc if you're *forced* to use a lot of clones. Incrementing the reference counter and *then* moving the Rc / Arc is often faster than cloning a large struct.

I do have to say that my time with Rust has gotten a lot easier thanks to Arc. It makes dealing with async stuff much better.

@@disguysn Arc is probably one of my favourite types because of that. People always bicker about its runtime overhead but it really is absolutely miniscule.

There is something to be said for a language designed so well that it funnels users to making the correct decisions simply by its syntax, and not requiring them to be a guru or understand the inner complexities of the compiler in order to game the system and get the best performance. Obviously Rust has much better potential in the "raw performance" category, but it all came at the cost of a clunky syntax and some very aggravating paradigms. I have been doing some Zig lately, and while it is not without its quarks, its approach feels to have struck a better balance between safety and usability. It has the guide rails, and forces the developer to be explicit when disregarding them, but not so obsessed about it that the language on a whole begins to suffer from it.

Every feature MUST be behind a Controller, a Service interface and implementation, a Dao interface and implementation.... The apps all took 10 seconds to start due to component scanning.... I don't have Go experience, but Rust + axum has already treated me better in every possible way. I'm skilled enough at this point that most borrow checker problems have become a non-issue. Even if the compilation is slower, the startup time is so much better that I'm still iterating faster... Good god...

[@hagaiak]

And now you can't do a simple `if (foo) { }` in TypeScript because your `number | null` type is truthy when it's either null or 0. True discriminant optionals are better, which is why TypeScript libraries exists to provide a real optional type.

[@fulconandroadcone9488]

@@hagaiak you should never treat number as a boolean unless you are doing C and don't have defined boolean type. You can use "123" as a number but 123 is a number "123" is a string. Drawback of TS is that it still allows implicit JS type casting which leads to a lot of confusion. If you want to check if something is null use x == null not if(x), empty string is seen as false by JS but in the end it is string not a boolean, use boolean for conditionals not numbers and string.

I think Prime is exaggerating the point about lifetime propagation. Most of the time Rust can infer lifetimes without annotations. When you add an explicit one, there's only a specific set of cases where it's going to propagate everywhere, and that's usually avoidable if you design your APIs more carefully. Granted, it's possible that you work yourself into a corner without realizing it.

If you want to see some nasty code with boss level Rust feature combos: generics with multiple generic parameters + multiple lifetimes + smart pointers... Have a look at Nom library source code!
