Yeah I keep hearing / reading about rust, even seen some demos but the demos all end with "oh no I'm not using this for anything". Still cool but ... want to see someone doing something in production / get their thoughts on that.

Edit: To be clear I'm not saying anyone isn't using it, this is just more of a comment about the impression I can get when I hear about X tech is so cool, but that's most of what I hear and at some point I want to see those same articles about real world use / experiences. I'm aware Mozilla and others are using it.

Huh? Besides Mozilla itself using it in the browser in several backends, there are tons of places where its used in production (and several articles on HN on the topic).

Where do you see all those demos who say "I'm not using this for anything"?

I've seen articles on Mozilla using Rust, Dropbox using Rust, MS using Rust (rustgrep used in VSC but also something in Azure IIRC), Google using Rust (Google Fuchsia), Facebook using Rust (Mononoke, etc), and so on.

Amazon is using Rust - Firecracker powers Lambda and Fargate: https://aws.amazon.com/blogs/aws/firecracker-lightweight-vir...

NPM is using Rust on the backend

I believe Discord is using Rust for their games store.

MS security devision is also proposing a trio of C#, Rust and constrained C++ (meaning no Cisms) for their software going forward.

I'm using it for an not-yet released product. Roughly 30k lines of code running on Windows, macOS, and Linux. Mostly high volume event processing and parsing.

Been a lot of fun to work with. Having spent 10 years doing C++ professionally before, I can't see myself ever looking back.

Once product is public later this year, I may see if I can talk more publicly about it.

That sounds like it would be very interesting.

We're doing a low level core functionality lib in Rust that is shared between Windows desktop, iOS and Android apps.

It works really well.

If we were to do it again, the core Rust lib would do much more and the platform native code would only be things that need to be like UI and notifications.

Thank you.

Our product is basically written in Rust (~40k LoC) [1]. When I say basically: there are a few backend components that are written in Java (i.e, ActiveMQ) and the frontend is TypeScript/React, but it is mostly Rust.

I'm not saying nobody is using it, just the volume of "hey this is so cool" gets to be a bit much and I want to see more "here it is solving problems in production for a real thing".

The explorations and small little demos and projects in a language is almost always higher than the number of production uses, it's just that in popular languages nobody cares to read much about it (or at least share is so it spreads), because it's already known. Rust is still fairly uncommon, so you're bound to see a lot of people announcing their experiences while playing around with it, and that can skew the perceived ratio of things.

I think the problem is solved by paying less attention to the stuff you care about less, and/or seeking out more production(y) uses if desired by looking in places where it's already common, such as /r/rust, where the content ratio will naturally fall more favorably towards production uses, libraries and advanced discussions since a minimum level of experience (or at least interest) can be assumed.
