I didn't touch the ui tests so why is it failing? O.o

mati865 · 2019-09-11T14:08:14Z

Guess you'll have to bless the tests:

- For more information about this error, try `rustc --explain E0478`.+ Some errors have detailed explanations: E0312, E0478.+ For more information about an error, try `rustc --explain E0312`.
