error[E0277]: `MyError` doesn't implement `std::fmt::Display`
|
|
--> tests/ui/missing-display.rs:4:10
|
|
|
|
|
3 | #[derive(Error, Debug)]
|
|
| ----- in this derive macro expansion
|
|
4 | pub enum MyError {
|
|
| ^^^^^^^ `MyError` cannot be formatted with the default formatter
|
|
|
|
|
= help: the trait `std::fmt::Display` is not implemented for `MyError`
|
|
= note: in format strings you may be able to use `{:?}` (or {:#?} for pretty-print) instead
|
|
note: required by a bound in `std::error::Error`
|

--> $RUST/core/src/error.rs

| pub trait Error: Debug + Display {
|
|
| ^^^^^^^ required by this bound in `Error`
|
|
= note: this error originates in the derive macro `Error` (in Nightly builds, run with -Z macro-backtrace for more info)
