I’m a hobbyist programmer, mostly in JavaScript, but I’d like to learn Rust. I’d like to use an open-source IDE that supports Language Server Protocol. I’m currently using WebStorm, which is not open-source, and doesn’t support LSP. I’ve checked out VS Codium, which is open-source and does support LSP, but it seems like it’s a hobbled version of VS Code that still phones home to Microsoft.

Are there and other IDEs that are FOSS and that support LSP?

Edit: Thanks everybody. I’m taking the path of least resistance and sticking with Webstorm and IntelliJ.
