<p>This module is dedicated to managing descriptor sets. There are three concepts in Vulkan
related to descriptor sets:</p>
<ul>
<li>A <code>DescriptorSetLayout</code> is a Vulkan object that describes to the Vulkan implementation the
layout of a future descriptor set. When you allocate a descriptor set, you have to pass an
instance of this object. This is represented with the <code>UnsafeDescriptorSetLayout</code> type in
vulkano.</li>
<li>A <code>DescriptorPool</code> is a Vulkan object that holds the memory of descriptor sets and that can
be used to allocate and free individual descriptor sets. This is represented with the
<code>UnsafeDescriptorPool</code> type in vulkano.</li>
<li>A <code>DescriptorSet</code> contains the bindings to resources and is allocated from a pool. This is
represented with the <code>UnsafeDescriptorSet</code> type in vulkano.</li>
</ul>
<p>In addition to this, vulkano defines the following:</p>
<ul>
<li>The <code>DescriptorPool</code> trait can be implemented on types from which you can allocate and free
descriptor sets. However it is different from Vulkan descriptor pools in the sense that an
implementation of the <code>DescriptorPool</code> trait can manage multiple Vulkan descriptor pools.</li>
<li>The <code>StdDescriptorPool</code> type is a default implementation of the <code>DescriptorPool</code> trait.</li>
<li>The <code>DescriptorSet</code> trait is implemented on types that wrap around Vulkan descriptor sets in
a safe way. A Vulkan descriptor set is inherently unsafe, so we need safe wrappers around
them.</li>
<li>The <code>SimpleDescriptorSet</code> type is a default implementation of the <code>DescriptorSet</code> trait.</li>
<li>The <code>DescriptorSetsCollection</code> trait is implemented on collections of types that implement
<code>DescriptorSet</code>. It is what you pass to the draw functions.</li>
</ul>
