So what do you use for Rust development?
I've heard a lot of people propose their wildly different setups for development in any language; I've heard of someone who used VSCode for browsing projects, and Vim for actual development of files. Then you have the extensive Emacs community, which is a recursive can of worms in it of itself.
I personally just use a terminal editor with TMux and Neovim with some nice quality of life configuration.
