I'm using SLY in Doom Emacs and would love to be able to see the signatures/types of the completion options and their docstrings in the completion popup itself, much like what you get in VSCode (or would get with emacs and rust-analyzer if I could get emacs to use rust analyzer, but no one will help me with that lmao). I can't seem to find documentation for how to enable this online, but ive seen videos where people using slime have it. Thanks!
