<p>This trait encapsulates the low-level functionality common to all
generators, and is the &quot;back end&quot;, to be implemented by generators.
End users should normally use the <code>Rng</code> trait from the <a href="https://docs.rs/rand"><code>rand</code></a> crate,
which is automatically implemented for every type implementing <code>RngCore</code>.</p>
<p>Three different methods for generating random data are provided since the
optimal implementation of each is dependent on the type of generator. There
is no required relationship between the output of each; e.g. many
implementations of <a href="RngCore::fill_bytes"><code>fill_bytes</code></a> consume a whole number of <code>u32</code> or <code>u64</code>
values and drop any remaining unused bytes.</p>
<p>The <a href="RngCore::try_fill_bytes"><code>try_fill_bytes</code></a> method is a variant of <a href="RngCore::fill_bytes"><code>fill_bytes</code></a> allowing error
handling; it is not deemed sufficiently useful to add equivalents for
<a href="RngCore::next_u32"><code>next_u32</code></a> or <a href="RngCore::next_u64"><code>next_u64</code></a> since the latter methods are almost always used
with algorithmic generators (PRNGs), which are normally infallible.</p>
<p>Algorithmic generators implementing [<code>SeedableRng</code>] should normally have
<em>portable, reproducible</em> output, i.e. fix Endianness when converting values
to avoid platform differences, and avoid making any changes which affect
output (except by communicating that the release has breaking changes).</p>
<p>Typically implementators will implement only one of the methods available
in this trait directly, then use the helper functions from the
[<code>impls</code>] module to implement the other methods.</p>
<p>It is recommended that implementations also implement:</p>
<ul>
<li><code>Debug</code> with a custom implementation which <em>does not</em> print any internal
state (at least, [<code>CryptoRng</code>]s should not risk leaking state through
<code>Debug</code>).</li>
<li><code>Serialize</code> and <code>Deserialize</code> (from Serde), preferably making Serde
support optional at the crate level in PRNG libs.</li>
<li><code>Clone</code>, if possible.</li>
<li><em>never</em> implement <code>Copy</code> (accidental copies may cause repeated values).</li>
<li><em>do not</em> implement <code>Default</code> for pseudorandom generators, but instead
implement [<code>SeedableRng</code>], to guide users towards proper seeding.
External / hardware RNGs can choose to implement <code>Default</code>.</li>
<li><code>Eq</code> and <code>PartialEq</code> could be implemented, but are probably not useful.</li>
</ul>

<p>This is the only method which allows an RNG to report errors while
generating random data thus making this the primary method implemented

directly to generate keys and to seed (infallible) PRNGs.</p>
<p>Other than error handling, this method is identical to <a href="RngCore::fill_bytes"><code>fill_bytes</code></a>;
thus this may be implemented using <code>Ok(self.fill_bytes(dest))</code> or
