Required Methods

fn get_description(&self) -> String

Returns the description of the exercise. This should help the user understand what should be done.

Provided Methods

fn get_expected_result(&self) -> String

Returns a String that should test the input provided by the user.

fn get_expected_results(&self) -> Vec<String>

Returns a Vector of Strings that one of it should test the input provided by the user.

fn get_sort_property(&self) -> String

Returns the property to sort the exercises. This is useful when you want to control the order in which the exercises appear. If this function is not implemented by a concrete Struct, the order of the exercises can be completely random.
