As I can see there is only on feature from nightly — #![feature(derive_default_enum)], to derive default trait for status. But with that it's not possible to use this crate as lib in stable toolchain.
Hi, I'll take a look and see why I had that in there and if it is possible to remove.
It looks like this feature will be supported very soon. I'll keep track of this and change to stable tool chain as soon as it lands.
That was only used in one place. I changed it out and published a new release that works with the stable tool chain. https://github.com/CalebEverett/arloader/releases/tag/v0.1.63
