   = help: the trait `std::fmt::Debug` is not implemented for `Error`
   = note: add `#[derive(Debug)]` or manually implement `std::fmt::Debug`
   = note: required because of the requirements on the impl of `std::fmt::Debug` for `&Error`
   = note: required for the cast to the object type `dyn std::fmt::Debug`
   = note: this error originates in a derive macro (in Nightly builds, run with -Z macro-backtrace for more info)
