Thank you @Rachelint and @Kev1n8 -- looks good to me; I had one question, but I don't think there is anything that would prevent this PR from merging.

I don't understand the use of vec! here - isn't this the same as creating size strings of lenght up to remaining_len?
Maybe this could be somehthing like
let string_iter = (0..size).map(|len|{ ?

Yes, I want to create size strings, and each one has remaining_len lenght.
🤔 Maybe it is a bit confused, I have improved it and added some comments.
