Cargo fix errors

Problem
Running cargo fix on rendy fails on two files. Asks to report but with full output.

Steps
Clone rustgd/rendy, run cargo fix.

Notes

Output of cargo version: cargo 1.31.0 (339d9f9 2018-11-16)

Full output: https://gist.github.com/termhn/f02fdee4b79563c47a1238a558a916aa

Thanks for the report. This looks to be due to a bad suggestion in the rust_2018_compatibility lints previously reported at rust-lang/rust#56327. You can remove the dyn keyword here and here to work around it, or not use the rust_2018_compatibility lints.

👍 After adding the edition = "2018" and re-running cargo fix, then compiling, I ended up needing to re-add those dyns to make it happy.
