error[E0369]: binary operation `==` cannot be applied to type `&Error`

LL | Error

note: an implementation of `PartialEq` might be missing for `Error`

= note: this error originates in the derive macro `PartialEq` (in Nightly builds, run with -Z macro-backtrace for more info)
|
|
help: consider annotating `Error` with `#[derive(PartialEq)]`
|

|

LL + #[derive(PartialEq)]
