Contiguous Iterators: A Refinement of Random Access Iterator

by Nevin Liber

Excerpt:

This is a proposal to add contiguous iterators to the standard, which is a refinement of random access
iterators.

A contiguous iterator is a random access iterator that also meets the following requirements:

std::pointer_from(i) == std::addressof(*i) (when i is dereferenceable)

std::pointer_from(i + n) == std::pointer_from(i) + n (when i + n is a valid iterator)
