        <h3>Description</h3>
        <p><span>This abstract interface provides a means</span> <span>for an algorithm to generically obtain a</span>
<span>modifiable, contiguous character buffer</span>
<span>of prescribed size. As the author of an</span>
<span>algorithm simply declare an rvalue</span>
<span>reference as a parameter type.</span></p>

<p><span></span></p>

<p><span>Instances of this type are intended only</span>
<span>to be used once and then destroyed.</span></p>

<h3>Example</h3>
<p><span>The declared function accepts any</span>
<span>temporary instance of `arg` to be</span>
<span>used for writing:</span></p>

<code>
void algorithm( string_token::arg&& dest );
</code>
<p><span>To implement the interface for your type</span>
<span>or use-case, derive from the class and</span>
<span>implement the prepare function.</span></p>
