Different compiler versions disagree on whether failure_derive macro is used or not

This leads to some compatibility issues. The code I have now compiles on 1.25.0 and 1.28.0 but reports an unused [macro_use] import for 1.31.0. https://travis-ci.org/stratis-storage/devicemapper-rs/jobs/466549505. Is this a bug in Rust, or something about the behavior of the failure_derive crate?

Going to close this. I think this might be because you are using failure_derive directly which is not intended.
