Here is my project on Github: GitHub - alimkoca/memorust: Simple and stupid flash card implementation in CLI
I want you to find unidiomatic code blocks in my code and criticize them. I can't ensure that the usage of the .clone() method is acceptable in iterations, loops, etc (memorust/memory_boxes.rs at master · alimkoca/memorust · GitHub).
The clone call is fine. Fundamentally, you're returning many strings, and each string that you return must be individually created somewhere.
That said, the way you're clearing the strings is poor. Do this instead:
Otherwise, you're throwing away the allocation that the
question variable owns on each iteration. It's better to reuse it.
