@rough-minister-58256 i'm using https://github.com/racer-rust/racer with emacs, which is neat but obv requires emacs. did you see john's message itc about his changes to the rust build yesterday? i have >100 tabs of rust docs open right now, along with the rust book -- i have felt pretty frustrated by borrow checking in the past but not recently. what type coercion are you working through?
