by dictionary definition, rust is not mainstream. it's not normal (common, typical, customary) for an engineer to interact with rust

[IshKebab]

I would consider it perfectly normal to discover something in my company or on Github was written in Rust. It's the 12th most popular language on Github by PRs according to this: https://madnight.github.io/githut/#/pull_requests/2022/1 (Shell and Nix don't count).

It's only 3 times less popular than C. As I said, very weird definition of mainstream.

The measure of "mainstream" should not be "projects on github" but: code deployed (or actively deploying) in production. GitHub is full of personal interest and research and unfinished projects.

It will come. It's not there yet.

I still argue it's not the language best suited for what a lot of people are trying to use it for. It has a niche, one that I like, but I fail to understand why it's being deployed for web services type applications. IMHO it's not a good fit.

There are plenty of reasons why it's a good fit for web services. It's fast, has great tooling, a great library ecosystem, and perhaps most importantly the strong type system and borrow checker mean you write far fewer bugs than in most other languages (C++, Java, Typescript, Go etc; maybe not Haskell).

The only reason I wouldn't use it in web services is because the whole ecosystem seems to have decided that everything has to be async despite that adding a ton of complexity and almost nobody needing it.

[solar-ice]

Entirely agree with that - and I'm a professional Rust dev, working with video. It's like using C++ for web services. Why would you do that?

[cmrdporcupine]

I think people are seduced by some of the modern language features (like pattern matching, etc) by some of the third party libraries, by async [careful!], and primarily also by the WASM story that seems to be kind of going along with Rust. And by the novelty. And by promise of vaguely defined "performance."

But none of this is unique to Rust. And I'm not convinced on the WASM stuff at all for writing web front ends, though I'm enamoured of it as a generic backend managed VM, but that's another story.

And I think adopting Rust in many shops with a mix of developer seniority levels will be a productivity killer. I think most places doing this kind of thing would probably be better off with TypeScript, or Kotlin. Or if they want to go more functional and exotic, F#, Scala, OCaml, or Erlang/Elixir, etc.

But for places where we've been doing C++ for years and setting off footguns all over the place? Rust is great! Love it.

If Rust leads to more languages for more domains adopting Rust-style enums and pattern matching (algebraic data types / sum types -- this idea predates Rust by decades, so "modern" is an interesting term to use), I'd call that a big win for everyone. :)

It's pretty tricky to do that in an untyped language. But TypeScript could have this, or maybe even already does?

[cmrdporcupine]

I mean, sure, why are we calling it "Rust-style"; it comes from ML and its descendants and Rust is obviously very influenced by them. When I say "modern" I really mean... finally learned from what "we" were "all" reading about on Lambda The Ultimate 20 years ago about languages designed 40 years ago that were not part of the mainstream until about 5-10 years ago :-)

AFAIK TypeScript doesn't have ML-style pattern matching, but its type system is fairly expressive and you can do something "like" it https://dev.to/gvergnaud/bringing-pattern-matching-to-typesc...

If you mean dynamically typed, then Elixir has it:

That’s not a metric I would start for defining mainstreamness. There are at least 2 orders of magnitude more program written in C that is not open-source, but part of a critical infrastructure.

[dagmx]

Yet here you are on a discussion about it, of many rust discussions. Many companies use it enough that most of the MANGA companies have openings for it.

How is that not mainstream by even your own definition? It’s consistently a part of the current zeitgeist.
