<p>If the <code>BufMut</code> is backed by disjoint slices of bytes, <code>bytes_vec_mut</code>
enables fetching more than one slice at once. <code>dst</code> is a slice of
mutable <code>IoVec</code> references, enabling the slice to be directly used with

<p>The entries in <code>dst</code> will be overwritten, but the data <strong>contained</strong> by
the slices <strong>will not</strong> be modified. If <code>bytes_vec_mut</code> does not fill every

<h2>Search Tricks</h2>
<p>
Prefix searches with a type followed by a colon (e.g.
<code>fn:</code>) to restrict the search to a given type.
</p>
<p>
Accepted types are: <code>fn</code>, <code>mod</code>,
<code>struct</code>, <code>enum</code>,
<code>trait</code>, <code>type</code>, <code>macro</code>,
and <code>const</code>.
</p>
<p>
Search functions by type signature (e.g.
<code>vec -> usize</code> or <code>* -> vec</code>)
