New Minimal Dependency vimrc with ALE

I stumbled onto a good simple adjustment to my minimal config while trying to figure out a good vim setup for Java, Rust, and Go. Yes I know I can just use VSCode and everything will just work, but for my home stuff I like to keep things relatively stripped down, maybe a few packages via homebrew to keep things up to date, but I no longer like to spend oodles of time every time I log in running updates on a hundred different packages, vscode often feels like this to me, a chain of updates if I haven't logged in for awhile.

What is this ALE thing in the title

Syntastic was one of the old trusty packages I would install through vim packages and it worked a treat but it has moved on as many projects do and the page actually recommended ALE. Ale provides a lot that syntastic didn't including completion and lsp support and usually it needs little to no configuration (it picked up golps instantly). I played around with it at work and integrated some other plugins and was pretty happy. Later when I started working on something at home I tried this more minimal version and still found it very pleasing to use. I have only installed airline and ALE in my vim plugins.

actual vimrc

Key changes are:

let g:ale_completion_enabled = 1
let g:ale_sign_column_always = 1
let g:airline#extensions#ale#enabled = 1
let g:rustfmt_autosave = 1
let g:ale_linters = {
\ 'rust': ['analyzer'],
let g:ale_fixers = {
 \   'rust': ['rustfmt'],
set omnifunc=ale#completion#OmniFunc
nmap <silent> <C-k> <Plug>(ale_previous_wrap)
nmap <silent> <C-j> <Plug>(ale_next_wrap)
