Whatever vim is in rhel 8 supports ale. Ale with rust has been great. Go to definition is flawless, all my conpile and clippy errors are underlined as I type and binding a key to ALECodeAction will apply the auto fix if it has one. Usually that is to import whatever I just used, which vscode would do automatically, but still its nice and having vscode use clippy as well as check bogs it down. And ale runs cargo-fmt on save. So yeah, nothing I'd wish different from it.

Edit: upon further thought, I don't like having to move my hand to the arrow keys to select from the auto complete list, even if there is only one thing and then hit enter, rather than hitting tab to pick whatever is left.
