rust nightly compiler bug

[karasjoh000]

Created some tests to run against a rocket backend and got this:

It says to report, so I thought I should report it...

[hellow554]

Can you please rerun the command and prepend RUST_BACKTRACE=1, e.g. RUST_BACKTRACE=1 cargo build and then post that as text? Thank you very much!

https://github.com/karasjoh000/forecast.git project will appear here soon once uploaded, sure I will run that

This seems like #55376. Can you update to a recent nightly?

[karasjoh000]

cargo 1.31.0-nightly (2d0863f65 2018-10-20)

[karasjoh000]

rustup update && cargo update <-- run this?

[karasjoh000]

okay looks like it is working after the update. Running on cargo 1.32.0-nightly (b3d0b2e54 2018-11-15)
