I love Goland, and it's honestly one of the products that I very much like to pay for. You can eventually pay a one time fee and use it forever (without updates).

I'm also using it for Rust, but it's missing CLion's powerful debugger UI - but I think that gdb is good enough :-)

The Rust plugin for IDEA Ultimate allows for debugging. I've used it while trying to contribute to open source software.

That’s how every JetBrains IDE subscription works, though. If you pay for a year, you get the version at the start of that year for perpetuity.

If you have IntelliJ ultimate, Goland is installable via the Go plugin for free. I use IntelliJ for go/js/python using their plugins and they work as well as the native apps (pycharm, webstorm, goland). Although it is a bit tougher to configure because you treat things more as modules.

I would (and do) use goland directly, but i think intellij handles the basics. I only use intellij for rust, and it does well enough there as well
