}</code></pre><details class="toggle top-doc" open><summary class="hideme"><span>Expand description</span></summary><div class="docblock"><p>A trait for reading references to <a href="../pod/trait.Pod.html" title="trait object::pod::Pod"><code>Pod</code></a> types from a block of data.</p>
<p>This allows parsers to handle both of these cases:</p>
<ul>
<li>the block of data exists in memory, and it is desirable
to use references to this block instead of copying it,</li>
<li>the block of data exists in storage, and it is desirable
to read on demand to minimize I/O and memory usage.</li>
</ul>
<p>A block of data typically exists in memory as a result of using a memory
mapped file, and the crate was written with this use case in mind.
Reading the entire file into a <code>Vec</code> is also possible, but it often uses
more I/O and memory.
Both of these are handled by the <code>ReadRef</code> implementation for <code>&amp;[u8]</code>.</p>
<p>For the second use case, the <code>ReadRef</code> trait is implemented for
<a href="struct.ReadCache.html" title="struct object::read::ReadCache"><code>&amp;ReadCache</code></a>. This is useful for environments where
memory mapped files are not available or not suitable, such as WebAssembly.
This differs from reading into a <code>Vec</code> in that it only reads the portions
of the file that are needed for parsing.</p>
<p>The methods accept <code>self</code> by value because <code>Self</code> is expected to behave
similar to a reference: it may be a reference with a lifetime of <code>'a</code>,
or it may be a wrapper of a reference.</p>
<p>The <code>Clone</code> and <code>Copy</code> bounds are for convenience, and since <code>Self</code> is
expected to be similar to a reference, these are easily satisfied.</p>
<p>Object file parsers typically use offsets to locate the structures
in the block, and will most commonly use the <code>*_at</code> methods to
read a structure at a known offset.</p>
<p>Occasionally file parsers will need to treat the block as a stream,
and so convenience methods are provided that update an offset with
the size that was read.</p>
