These exposition-only concepts specify that no exceptions are thrown from operations required by the specialized <memory> algorithms on ranges.

For the definitions of /*nothrow-input-iterator*/, /*nothrow-forward-iterator*/, /*nothrow-bidirectional-iterator*/ and /*nothrow-random-access-iterator*/, see this page.

Semantic requirements

1) A type R models nothrow-input-range only if no exceptions are thrown from calls to ranges::begin and ranges::end on an object of type R.

5) A type R models nothrow-sized-random-access-range only if no exceptions are thrown from calls to ranges::size on an object of type R.

Notes

These concepts allow some operations on ranges to throw exceptions.
