This video playlist from typecraft helped me a lot to set up a minimal neovim config: https://m.youtube.com/playlist?list=PLsz00TDipIffreIaUNk64KxTIkQaGguqn
I once in a while, improve, add or remove plugins and settings, whenever I find it necessary.
I use this rust plugin: https://github.com/mrcjkb/rustaceanvim However I haven't used Rust very much in my neovom set up as of now.
Another good starting point for a neovim config is here: https://github.com/nvim-lua/kickstart.nvim
Have fun.
