pub struct CodeIdentifier {

data: Option<String>

Нямаш нужда да пазиш Option<String> тук. Ако нямаш валиден идентификатор, просто няма да конструираш CodeIdentifier.

/// Функцията ще върне Option<CodeIdentifier>, което ще бъде:

let chek_two = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_";

В условието описахме, че проверката е дали символа е is_alphabetic(), и това включва доста повече от латинската азбука. А и щеше да е по-лесно да го имплементираш с викане на този метод, вместо да изброиш азбуката и да викаш contains :).
