remove failure

[aep]

failure doesn't work on mips because it depends on backtrace.
It looks trivial to remove, and i would just open a PR, but i'm not sure what the original intend of adding it was. Is this something that should be behind a feature flag?

[tarcieri]

This crate uses failure with default-features = false and therefore you shouldn't be encountering any issues related to the backtrace crate (it is an optional dependency of failure and gated on the std feature).

Can you post what error you're encountering? It looks like from https://github.com/aep/cr2/issues/1 another crate is activating the std feature of failure, in which case this is not the culprit you're looking for.

interesting. the other crate turns out to only have a build dependency to failure.
i wonder if that confuses cargo. will dig deeper, thanks

[tarcieri]

Yes, it's a known deficiency of cargo (it does not support separate dependency resolution for dev / build). See:

rust-lang/cargo#2589
rust-lang/cargo#4664
rust-lang/cargo#4866

Darn. will remove the other thing then to see if that makes it all work. thanks!
