<p>This type is a sort of “double cursor”. It tracks three regions in the
buffer: a region at the beginning of the buffer that has been logically
filled with data, a region that has been initialized at some point but not
yet logically filled, and a region at the end that may be uninitialized.
The filled region is guaranteed to be a subset of the initialized region.</p>
<p>In summary, the contents of the buffer can be visualized as:</p>
<div class="example-wrap"><pre class="language-not_rust"><code>[ capacity ]
[ filled | unfilled ]
[ initialized | uninitialized ]</code></pre></div>
<p>It is undefined behavior to de-initialize any bytes from the uninitialized
region, since it is merely unknown whether this region is uninitialized or
not, and if part of it turns out to be initialized, it must stay initialized.</p>
