<p>
An unconstrained_set_of set view is a view with no constraints. The use
of these kind of view boost the bimap performance but the view can not
be accessed. An unconstrained view is an empty class.

We adopt the scheme outlined in the <a class="link" href="bimap_reference.html#complexity_signature_explanation">complexity
signature section</a>. An unconstrained view can not be accessed by
the user, but the formulas to find the order of an operation for a bimap
hold with the following definitions. The complexity signature of a <code class="computeroutput"><span class="identifier">unconstrained_set_of</span></code> view is:

<p>
Views cannot be serialized on their own, but only as part of the <code class="computeroutput"><span class="identifier">bimap</span></code> into which they are embedded.
In describing the additional preconditions and guarantees associated
to <code class="computeroutput"><span class="identifier">list_of</span></code> views with
respect to serialization of their embedding containers, we use the concepts
defined in the <code class="computeroutput"><span class="identifier">bimap</span></code>
serialization section.
