[Help] Cannot build on nightly?

[YetAnotherMinion]

I was attempting to integrate this library with diesel while using the nightly compiler.

Do you know off the top of your head problem changes in nightly that would cause build failures? It is fine if you don't know. I can debug it myself but I wanted to check for any possible leads from the people who know the most about this library first. Please tell me if you don't know so I can begin working on the problem.

All of the errors look like the blanket trait implementations not being found by the compiler. If you know the name of the problem or the rust issue the this comes from that would be a huge help.

This is a regression in rustc on both beta and nightly (here is the link to the rust issue).

This should be fixed now, as per rust-lang/rust#54467 being closed
