<p>This buffer is especially suitable when you want to upload or download some data regularly
(for example, at each frame for a video game).</p>
<h1 id="usage" class="section-header"><a href="#usage">Usage</a></h1>
<p>A <code>CpuBufferPool</code> is similar to a ring buffer. You start by creating an empty pool, then you
grab elements from the pool and use them, and if the pool is full it will automatically grow
in size.</p>
<p>Contrary to a <code>Vec</code>, elements automatically free themselves when they are dropped (ie. usually
when you call <code>cleanup_finished()</code> on a future, or when you drop that future).</p>
<h1 id="arc-like" class="section-header"><a href="#arc-like">Arc-like</a></h1>
<p>The <code>CpuBufferPool</code> struct internally contains an <code>Arc</code>. You can clone the <code>CpuBufferPool</code> for
a cheap cost, and all the clones will share the same underlying buffer.</p>
