Procedural Macros & Custom Derive Challenge

Objectives

• Implement the CustomDebug derive to output the fields of a struct in a custom way.
  • The CustomDebug derive will implement the Debug trait for the struct.
  • Use syn::DeriveInput to get the fields of the struct.
  • Iterate over each field and output the field in a nice way.
• Extra: Use custom attributes to affect your CustomDebug output.
  • Only output fields that are tagged with the #[debug] attribute.
