What happened
After I renamed a struct and tried to build my project compiler panicked with following message. However after doing a clean build everything was successful. I don't know how to extract code that is a cause for this panic, so here is my repo at the point of failure. Specifically the change I made was in file src/statusbar.rs. I also have a copy of target directory that fails to build. I won't attach it here because after compression it is 268M in size, but if is will be helpful I can share it in any way you wish.
If there is some additional information I can provide please let me know, I'll be happy to help. This is my first bug report of this kind, so I'm kinda guessing what should I include in it. Please also forgive me for butchering grammar since I am not a native-speaker.
