error: Expected type name after 'path: '.

       The type must be a struct that derives the appropriate trait:
       - path: Type   - Type must derive Path
       - body: Type   - Type must derive Type (for JSON parsing)
       - query: Type  - Type must derive Query

       Example:
       #[derive(Path)]
       struct UserId { id: String }

       GET "/users/{id}" => handler(path: UserId)
