I.e. something like:

#[derive(Debug)]
#[debug("{name}={value:?}")]
struct Arg {
  name: String,
  value: String
}

Does this still not work with v1.0.0-beta.2?

@JelteF we have this on fields level for Debug, but missing on item level.

Add support for debug attributs on structs and enum variants (#279)
6a4772a 
Adds support `debug` attributes on structs an enum variants like this:
```rs
#[derive(Debug)]
#[debug("{name}={value:?}")]
struct Arg {
  name: String,
  value: String
}
```

Before the `debug` attribute could only be used on fields of a struct or variant.

Resolves #277
