> Cargo + RLS are the best ecosystem tools I've seen in any language.

In my experience the java profilers and debuggers are still better than anything that's available for rust.

RLS is great on a fundamental level (decoupling IDE from compiler), but it still has to catch up in functionality with the total compiler integration that for example eclipse has with ecj.

We don't use Java. Java is old, of course it has plenty of tooling, but it also has a mountain of negatives in it's own right, besides the fact that it's not suitable for systems level work.

I guess it is a matter of what kind of systems one is developing, given its use in embedded platforms.

You switched from C++ to Rust and don't use Java because Java is old.

You've made at least one person's mood a little lighter today. Thank you.

You misread. Java being old is counted as a positive here; Java is old, so it has plenty of tooling, is the message. Despite this, they are not using Java :)

Yep, Rust still needs to do a lot to catch up with Java and .NET eco-systems.

Not really, like I said, java isn't really suitable for systems level work, or a good choice for FFI to C/C++. There are also a lot of disadvantages to using Java. Java lacks some of the compile time safety features of Rust. It has high level features like Sum types that Java does not have. The owners of Java have also sued reimplementors as well, which I think should give anyone pause about using it to do business with.

As I mention in another thread, it is a matter of what kind of systems level work you mean, given its successful use in embedded platforms, namely military, office devices, manufacturing automation and IoT.

Kotlin and Scala have Sum types, and Rust still needs to catch up with Scala's type system.

The owners of Java only sue reimplementors that don't respect licenses, like Microsoft and Google.

None of other commercial third parties has had any issue with Java owners.

Naturally I am not advocating for you to use Java instead of Rust, rather that it also has its uses in system work, and it is a valid option in scenarios where having a GC enabled language isn't a problem.
