Type hints?

[gcb]

Specifically with rust lsp (but i've seen similar unanswered questions for other languages here), is there a way to get type hints?

The work around i'm using is to just add a : String and then get an error which shows me the type, like "found String, expected TheTypeIWantedToKnow".. but that seems way too convoluted.

I don't need it overlayed on the code like most "modern" IDEs do. I am fine with a :ALE... call or on cursor move. Is there anyway to just show the inferred type without forcing the error?
