I think I've discovered Rust somewhere around the year 2012. Back then it was much different language than it is today. It had green-threads, @ and ~ were used a lot, and there was even a GC.

Rust caught my attention because I was looking for a language for myself. I always considered myself “a C guy”: a bottom-up developer, that first learned machine code, then learned higher level programming. And while C was my language of choice, I couldn't stand it anymore.

I was tired of how difficult it was to write a correct, robust software in C, especially:

  • inability to create solid abstractions and nice APIs,
  • segfaults, double checking my pointers and general lack of trust in my code,
  • make and make-likes building system.

I loved the simplicity and minimalism, I loved the flexibility and control, but I couldn't stand primitivism and lack of modern features.

With time I grew more and more fond of Rust. The language kept evolving in a direction that was my personal sweet spot: a modern C. And at some point I realized I'm in love with Rust. And I still am today, after a couple of years of using it.

Just look at my github profile. It has “Rust” written all over it. And check how my contributions grew since 2013. Rust made me much more productive and enthusiastic about programming.

So let me tell you why is Rust my darling programming language.

TL;DR

The biggest strength of #Go, IMO, was the FAD created by the fact that it is “backed by Google”. That gave Go immediate traction and bootstrapped a decently sized ecosystem. Everybody knows about it, and have a somewhat positive attitude thinking “it’s simple, fast, and easy to learn”.

I enjoy (crude but still) static typing, compiling to native code, and most of all: native-green thread, making Go quite productive for server-side code. I just had to get used to many workarounds for lack of generics, remember about avoid all the Go landmines and ignore poor expressiveness.

My favorite thing about Go, is that it produces static, native binaries. Unlike software written in Python, getting software written in Go to actually run is always painless.

However, overall, Go is a poorly designed language full of painful archaisms. It ignores multiple great ideas from programming languages research and other PL experiences.

“Go’s simplicity is syntactic. The complexity is in semantics and runtime behavior.”

Every time I write code in Go, I get the job done, but I feel deeply disappointed.
