| 18 | [heading Description] |
| 19 | |
| 20 | `rotate_copy` rotates the elements in a range. It copies the two ranges `[begin(rng), middle)` and `[middle, end(rng))` to `out`. |
| 21 | |
| 22 | [heading Definition] |
| 23 | |
| 24 | Defined in the header file `boost/range/algorithm/rotate_copy.hpp` |
| 25 | |
| 26 | [heading Requirements] |
| 27 | |
| 28 | * `ForwardRange` is a model of the __forward_range__ Concept. |
| 29 | * `ForwardRange` is mutable. |
| 30 | * `OutputIterator` is a model of the `OutputIteratorConcept`. |
| 31 | |
| 32 | [heading Precondition:] |
| 33 | |
| 34 | * `[begin(rng), middle)` is a valid range. |
| 35 | * `[middle, end(rng))` is a valid range. |
| 36 | |
| 37 | [heading Complexity] |
| 38 | |
| 39 | Linear. Exactly `distance(rng)` elements are copied. |
