| 15 | [heading Description] |
| 16 | |
| 17 | `swap_ranges` swaps each element `x` in `rng1` with the corresponding element `y` in `rng2`. |
| 18 | Returns a reference to `rng2`. |
| 19 | |
| 20 | [heading Definition] |
| 21 | |
| 22 | Defined in the header file `boost/range/algorithm/swap_ranges.hpp` |
| 23 | |
| 24 | [heading Requirements] |
| 25 | |
| 26 | * `SinglePassRange1` is a model of the __single_pass_range__ Concept. |
| 27 | * `SinglePassRange1` is mutable. |
| 28 | * `SinglePassRange2` is a model of the __single_pass_range__ Concept. |
| 29 | * `SinglePassRange2` is mutable. |
| 30 | |
| 31 | [heading Complexity] |
| 32 | |
| 33 | Linear. Exactly `distance(rng1)` elements are swapped. |
