-/// An iterator is a lazily evaluated sequence of element.
-///
-/// Iterators are useful when working with collections that are too large to
-/// fit in memory (or those that are infinite in size) as they only require the
-/// elements currently being processed to be in memory.
-///
-/// As a lazy data structure no work is done when an iterator is filtered,
-/// mapped, etc, instead a new iterator is returned with these transformations
-/// applied to the stream. Once the stream has all the required transformations
-/// applied it can be evaluated using functions such as `fold` and `to_list`.
