feature request: format on buffer save

[gozes]

it be nice if there was a variable I could set to t to say to cargo mode to run cargo format when I save a buffer. I tried calling the cargo-process-fmt from my config with a before save hook but it dosn't seam to work

rust-mode already has this feature, so why duplicate?

I have this in my .emacs:

(use-package rust-mode
    :mode "\\.rs\\'"
    :init
    (setq rust-format-on-save t))

Thanks for integrating cargo goodies into emacs.

judging by the last comment, we should consider this issue closed, no?
