Hard disagree. Rust brings a lot to the table for a web app. Compiled vs interpreted makes it easier to catch (syntax) errors beforehand. You can even go as far as compiled templates. Mapping JSON (or whatever) to strongly typed objects is great. Dependency management is best in class. I rather like diesel.rs (although it is very much an acquired taste) especially if you treat it like a safe query builder rather than an ORM.

The single biggest problem I've run into is that there's no real good story for a web app framework (especially since everyone's gone crazy over async). Rocket is perhaps a bit too magical for rust folks and it's been abandoned, but I rather liked it. I've warmed up to axum, but all this async stuff still rubs me the wrong way.

And, yes, compile times still suck.

cough C#. You also get LINQ. And a fairly heavy amount of web frameworks in ASP.NET / Razor.


Or Java, F#, Scala, Kotlin, Haskell. If we were to randomly pick a language, chances are it could be a good fit for these — Rust became as well-known as is because it was made for a different niche, where there were no competition.


Hell, even Python can map JSON to a strongly typed object. I am a firm fan of Pydantic and its competitors when dealing with JSON blobs. No-one deserves a KeyError in prod code.


Haskell is a beautiful language, but I find their web frameworks rather cumbersome to work with personally.

Do crates have namespaces that ownership is verified for?


Crate namespaces is best-in-class++ feature and currently not available.


Yeah, I ask because the JVM world has had that since... whenever Maven's central repository came about [0][1][2], I guess, and it ensures that there's no debate about namesquatting [3], nor typosquatting attack vectors [4].

I am constantly baffled that NPM, PyPi, crates.io etc. didn't copy this idea for those last two reasons. In my mind, it's not quite best in class without it.

Although all of those things are true, I think the main point being made is why choose Rust for that, instead of Go, .NET, etc, any of which offer everything you've outlined as being worth having, while having fewer of the downsides of Rust.


To me, one thing missing from most popular web languages is the single best part of Rust: A well-defined handling of the non-happy path.

I'm talking about things like exhaustive "switches", built-in, ENFORCED handling of "missing" values (null, undefined), and finally useful error handling.

I actually don't need any of the baremetal features of Rust. It's just that most of it's "zero-cost" abstractions are still far superior to those of other languages.


Haskell, Scala, F#, OCaml.

(Some dislike it, but Java’s checked exceptions are exact homologous of result types)


The problem with Java exceptions is that they have very poor generic support.

Outside of that, yeah they just differ in very low-level aspects that most developers don't even know about.


  any of which offer everything you've outlined 
They don't, that's the "problem". Off the top of my head dependency management in Go is not best in class to put it charitably. .NET will tie you more closely to Windows. Sure, mono is a thing but you'll have more packages to choose from and fewer compatibility issues running .NET on Windows.


Mono? 2000 and late called and want their .NET implementation back. Now it's all about the .NET formerly known as "Core".


Web development for .NET is multiplatform for quite some years now. https://en.wikipedia.org/wiki/.NET

Mono is mostly only relevant if you need platform specific capabilities that wont be covered in .NET.


Your knowledge of the .Net ecosystem is a bit out of date. It's had first class support for mac and linux for 7-8 years now.


First class support on Linux and Mac with caveats. Zero snark intended.


Arguably TypeScript is pretty close to as safe while being less work.


Perhaps. But TS is still Javascript under the hood which means implementation details leak and they smell awful. If they didn't it'd come down to a preference for compiled vs interpreted.

The number one syntactical beef I've is operators. e.g. == vs ===, ""+number.
