I still need flycheck-rust to make flycheck plays well with Cargo project.
without flycheck-rust, I will got this error:

Suspicious state from syntax checker rust-cargo: Flycheck checker rust-cargo returned 101, but its output contained no errors: error: no library targets found in package `rustprj`

Try installing a more recent version of rust-cargo, and please open a bug report if the issue persists in the latest release.  Thanks!
