|
* [*Precondition:] The `value_type` of the range is comparable with `operator==()`.
|
|
* [*Postcondition:] For all adjacent elements `[x,y]` in the returned range, `x==y` is false.
|
|
* [*Range Category:] __forward_range__
|
|
* [*Range Return Type:] `boost::uniqued_range<typeof(rng)>`
|
|
* [*Returned Range Category:] The minimum of the range concept of `rng` and __forward_range__.
