I see where you come from. I first turned to Go, but at the end of the day it was a nice language but it didn’t tick my boxes. One of my main issues for backend servers, is for them to be robust. They should never fail in runtime. That means error handling is quite important, and as few runtime errors as possible. Go, fails this hard. The strictness of Rust, may be a pain while learning, and some syntax may be less than optimal, but the result will almost never fail in production. I have in fact never had a backend I wrote fail in production. The error handling also makes it easy to find any errors due to things out of my control. I switched a project from Java to Rust, and the log shrunk by a factor 10.

Note, I still use Go sometimes, but it is not my go to language. And on a second note, that you point to .unwrap() indicates that you never really used rust to write a backend, since use of .unwrap() will panik if you use that. You normally use .unwrap_or(…) or some other better construct. Also, complaining about unwrap() would indicate that you prefer a null pointer issue? Because, dropping null/nil is one of the great design choices, having null/nil is just a recepie for getting a runtime crash.

I’ve used Go for a similar amount of time as you. I started with Go 1.0 when I pitched it to my company at the time, and then migrated all of our BE code to Go. It solved the problems we had at the time, and I certainly don’t regret that decision.

However, I ran into a ton of issues that I really don’t think I should have. For example:

• dumb bugs stemming from nil and weird interaction with interfaces (e.g. interface{}((*int)(nil)) != nil); honorable mention, functions attached to nil types can still be called, so the source of the nil could be hard to find
• map isn’t thread safe; why??
• nothing like Arc in Go, either use a channel or DIY with a mutex

And so on. Go strives to be easy to write, but it doesn’t do much to hide the footguns. So it’s like C, but at least you get panics instead of SEGFAULTs.

These days I much prefer Rust. I followed Rust pre-1.0, and I’ve used it a bit for personal projects since 1.0. It has come a long way, and I think it’s finally at a point where the barrier to entry is low enough and the ecosystem is robust enough that it can be a decent alternative to Go. I like that it doesn’t hide the complexity and forces you to deal with design problems at compile time instead of running into them randomly.

If Rust is too much, I prefer Python.

I wish Go would do something about its footguns. I honestly don’t like using it anymore because I get a ton of complexity with goroutines and whatnot, and very little to help manage it. The main thing I miss is pprof, and I find I haven’t needed it with Rust because things just run better.

I disagree. As someone that learnt go first then rust I much prefer rust in almost every way. The more I learnt Go the more it bothered me, so many promises it made were broken and so many good ideas half implemented. And the more I learn rust the more I enjoy it, it fixed most of the issues I had with Go and fixes a lot of issues I constantly see in Go code in production settings.

How would I know that I’m missing an import when typing a demonstration from some website?

I don’t see how this is an issue? You have a use somecrate at the top of a file that tells you you need something external, demonstations online will only really have crate use statements so it is never really a problem to tell. If they are missing? Well, go has the same but worst problem as you cannot easily guess the import you need for it as you need a full url.

What’s up with the ugly ( || keyword) syntax or :: or .unwrap() .

No more ugly than

func() { ... }

or

if err != nil {
    return err;
}

Because of ownership you’re forced into certain hierarchies, which make the code ugly and hard to read.

I dont know what you mean by this? The code rust encourages you into IMO is generally far more readable and less bug prone than a lot of languages.

Rust is a much harder language to learn and get into. But I still find it gets better every day and you learn better ways go doing things. In go if there is something you don’t quite like you re typically stuck doing it the one go way in every situation.

Because of ownership you’re forced into certain hierarchies, which make the code ugly and hard to read.

For non-gc languages you always have ownership, in most languages you just have to keep track of it manually. And whenever the rust compiler gives an error, you would most likely have had a future issue in another language. For gc languages, this may still exist if you share data between threads, causing possilbe race conditions and data corruption. So, the ownership/borrow model is just a formalization of implicit rules that exists in most languages.

Sounds like you don’t understand Rust. It’s more difficult to learn than Go. Go can be picked up by an experienced developer in a day. Mostly becauee there isn’t much in the language so there isn’t much to learn.

Try learning Rust properly before writing code. Learn the concepts. It’s not Python where you hack something together that maybe kinda works.
