Feature Request: Rust Support

[ghost]

I've been working on integrating a Rust project with a large multi-language repository, and we're successfully building Rust binaries via rules_rust and cargo raze. However, we have not been able to get the projects working within CLion or Intellij IDEA, I think in part because the plugin does not yet support it.

Is Rust support something that the Intellij plugin authors would be open to? I am happy to dedicate time to making this come to fruition, if it is desired. Roughly speaking, what would it take to get this working?

@jin there seems to already be support for go, cpp, dart, javascript, python, scala, kotlin and java.

What is the process for adding a new language? Barring scala which wix added support for, each of the existing languages are used internally within Google. I presume one concern is who would be on the hook for supporting the language support after the initial implementation

[jin]

Currently, we don't have bandwidth or domain expertise to support new languages like Rust, and there isn't a process to add a new language yet. It's possible to work on a fork of this project to add Rust support, but until the details are ironed out, we cannot support this yet.

One of the things that's high on my list to do is to implement a pluggable framework so that rule owners / domain experts (e.g. rules_rust) can integrate with this plugin without having to extend the core IntelliJ plugin, similar to how Starlark has provided Bazel core with extensibility.

Any updates on this? Will this be scoped out or prioritized in/for 2021?

By the way, could someone link an example of a project that uses Bazel with Rust?

https://github.com/bazelbuild/rules_rust/tree/master/examples has a couple of samples.
I can build a repo that mimics the common components used in internal monorepos using bazel if it might help.
And here you can find an example of crates where cargo raze was used to generate build files:

Is forking this project still seen as the best way to getting Rust support added given the current state of the project?

Would you accept a PR to add direct Rust support now? Or...

...is this completely blocked on implementing such a pluggable framework?

I've opened a PR which integrates with the IntelliJ Rust plugin to deliver Rust support.

• Rust Support #3222

It depends on

• Support for Rust projects built with Bazel intellij-rust/intellij-rust#8491

I've uploaded an example project, and demo of the plugin's capabilities, at https://github.com/vaticle/bazel-intellij-rust-example

bazel-intellij-rust-demo.mov

The PR's architectures are suboptimal, looking for some insider knowledge to bring them to production grade!
