I mean who'd want to and why bother trying to support that use case? Basically none of Rust's value proposition exists for a web app while nearly every single one of the downsides do.
The pieces and features i wanted exist but tying them together was not always straight forward.
From the top of my head I used:
- actix-web
- tracing (logging)
- sea-orm
- config from yaml files and a custom implementation to allow profiles.
- utoipa (for openapi and swagger ui)
- thiserror
In a professional context I would not have used Rust for this project, but it was quite fun to explore it's possibilities and rich crate ecosystem.
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.
The number one syntactical beef I've is operators. e.g. == vs ===, ""+number.
any of which offer everything you've outlined
Mono is mostly only relevant if you need platform specific capabilities that wont be covered in .NET.
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.
(Some dislike it, but Java’s checked exceptions are exact homologous of result types)
Outside of that, yeah they just differ in very low-level aspects that most developers don't even know about.
Do crates have namespaces that ownership is verified for?
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.

cough C#. You also get LINQ. And a fairly heavy amount of web frameworks in ASP.NET / Razor.
I write my web apps in C++. They tend to be little bit more than just query database / update database. They're exposed as JSON based RPC and can be accessed by JS front end from browser or third party systems we interact with. The performance is stellar and the code size is not much different comparatively to using PHP / Ruby / Python / your_pet_goes_here.
