Решението ти не се компилира заедно с пълния тест.

Структурите FibIter и RevFibIter трябва да са публично достъпни, т.е.
pub struct FibIter { ...
pub struct RevFibIter { ...

Функциите fib_split, fib_split_n и fib_split_n_symmetric трябва да са свободни функции, а не методи на FibIter. Само new, next и rev трябва да са методи.

Прочети отново указанията за предаване на домашни, там е написано как можеш да си тестваш проекта с базовия тест, за да си сигурен, че се компилира

За да пуснете теста:

  • Запазете тестовия файл като tests/test_basic.rs (в проекта, инициализиран по-горе с cargo new)
  • Изпълнете следната команда: cargo test

За пояснение главната директория на проекта трябва да съдържа Cargo.toml, src/, tests/.
