Contiguous Iterators

by Jens Maurer

Excerpt:

There are four containers in the standard library that guarantee contiguous storage: vector, string, valarray, and array. In the Library Fundamentals TS, there is also string_view. This paper introduces the term "contiguous iterator" as a refinement of random-access iterator, without introducing a corresponding contiguous_iterator_tag, which was found to break code during the Issaquah discussions of Nevin Liber's paper N3884 "Contiguous Iterators: A Refinement of Random Access Iterators".
