C++ named requirements: LegacyContiguousIterator (od C++17)

A LegacyContiguousIterator is a LegacyIterator whose logically adjacent elements are also physically adjacent in memory.

A pointer to an element of an array satisfies all requirements of LegacyContiguousIterator.

Requirements

The type It satisfies LegacyContiguousIterator if

The type It satisfies LegacyIterator And, for every

  • a, a dereferenceable iterator of type It
  • n, an integral value

such that

  • a + n is a valid and dereferenceable iterator value

then

  • *(a + n) is equivalent to *(std::addressof(*a) + n).

Standard library

The following standard library types are LegacyContiguousIterators.

Notes

Fancy pointer to object types are also required to satisfy LegacyContiguousIterator.

LegacyContiguousIterator is replaced with the contiguous_iterator concept: iterator types in the standard library that are required to satisfy LegacyContiguousIterator in C++17 are required to model contiguous_iterator in C++20. (od C++20)
