ability to reseed it.</p>
<p><code>ReseedingRng</code> reseeds the underlying PRNG in the following cases:</p>
<ul>
<li>On a manual call to <ahref="../../../rand/rngs/adapter/struct.ReseedingRng.html#method.reseed"><code>reseed()</code></a>.</li>
<li>After <code>clone()</code>, the clone will be reseeded on first use.</li>
<li>After a process is forked, the RNG in the child process is reseeded within
the next few generated values, depending on the block size of the
underlying PRNG. For ChaCha and Hc128 this is a maximum of
15 <code>u32</code> values before reseeding.</li>
<li>After the PRNG has generated a configurable number of random bytes.</li>
</ul>
<h1id="when-should-reseeding-after-a-fixed-number-of-generated-bytes-be-used"class="section-header"><ahref="#when-should-reseeding-after-a-fixed-number-of-generated-bytes-be-used">When should reseeding after a fixed number of generated bytes be used?</a></h1>
<p>Reseeding after a fixed number of generated bytes is never strictly
<em>necessary</em>. Cryptographic PRNGs don't have a limited number of bytes they
can output, or at least not a limit reachable in any practical way. There is
no such thing as 'running out of entropy'.</p>
<p>Occasionally reseeding can be seen as some form of 'security in depth'. Even
if in the future a cryptographic weakness is found in the CSPRNG being used,
or a flaw in the implementation, occasionally reseeding should make
exploiting it much more difficult or even impossible.</p>
<p>Use <ahref="../../../rand/rngs/adapter/struct.ReseedingRng.html#method.new"><code>ReseedingRng::new</code></a> with a <code>threshold</code> of <code>0</code> to disable reseeding
<p>Although unlikely, reseeding the wrapped PRNG can fail. <code>ReseedingRng</code> will
never panic but try to handle the error intelligently through some
combination of retrying and delaying reseeding until later.
If handling the source error fails <code>ReseedingRng</code> will continue generating
data from the wrapped PRNG without reseeding.</p>
<p>Manually calling <ahref="../../../rand/rngs/adapter/struct.ReseedingRng.html#method.reseed"><code>reseed()</code></a> will not have this retry or delay logic, but
