|
|
<p>This is the “standard small” RNG, a generator with the following properties:</p>
|
|
<ul>
|
|
<li>Non-<a href="https://rust-random.github.io/book/crate-reprod.html">portable</a>: any future library version may replace the algorithm
|
|
and results may be platform-dependent.
|
|
(For a small portable generator, use the <a href="https://crates.io/crates/rand_pcg">rand_pcg</a> or <a href="https://crates.io/crates/rand_xoshiro">rand_xoshiro</a> crate.)</li>
|
|
<li>Non-cryptographic: output is easy to predict (insecure)</li>
|
|
<li><a href="https://rust-random.github.io/book/guide-rngs.html#quality">Quality</a>: statistically good quality</li>
|
|
<li>Fast: the RNG is fast for both bulk generation and single values, with
|
|
consistent cost of method calls</li>
|
|
<li>Fast initialization</li>
|
|
<li>Small state: little memory usage (current state size is 16-32 bytes
|
|
depending on platform)</li>
|
|
</ul>
|
|
<p>The current algorithm is
|
|
<code>Xoshiro256PlusPlus</code> on 64-bit platforms and <code>Xoshiro128PlusPlus</code> on 32-bit
|
|
platforms. Both are also implemented by the <a href="https://crates.io/crates/rand_xoshiro">rand_xoshiro</a> crate.</p>
|
|
<h3 id="seeding-construction"><a class="doc-anchor" href="#seeding-construction">§</a>Seeding (construction)</h3>
|
|
<p>This generator implements the <a href="../trait.SeedableRng.html" title="trait rand::SeedableRng"><code>SeedableRng</code></a> trait. All methods are
|
|
suitable for seeding, but note that, even with a fixed seed, output is not
|
|
<a href="https://rust-random.github.io/book/crate-reprod.html">portable</a>. Some suggestions:</p>
|
|
<ol>
|
|
<li>To automatically seed with a unique seed, use <a href="../trait.SeedableRng.html#method.from_rng" title="associated function rand::SeedableRng::from_rng"><code>SeedableRng::from_rng</code></a>:
|
|
<div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">use </span>rand::SeedableRng;
|
|
<span class="kw">use </span>rand::rngs::SmallRng;
|
|
<span class="kw">let </span>rng = SmallRng::from_rng(<span class="kw-2">&mut </span>rand::rng());</code></pre></div>or <a href="../trait.SeedableRng.html#method.from_os_rng" title="associated function rand::SeedableRng::from_os_rng"><code>SeedableRng::from_os_rng</code></a>:
|
|
<div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">let </span>rng = SmallRng::from_os_rng();</code></pre></div></li>
|
|
<li>To use a deterministic integral seed, use <code>seed_from_u64</code>. This uses a
|
|
hash function internally to yield a (typically) good seed from any
|
|
input.
|
|
<div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">let </span>rng = SmallRng::seed_from_u64(<span class="number">1</span>);</code></pre></div></li>
|
|
<li>To seed deterministically from text or other input, use <a href="https://docs.rs/rand_seeder/latest/rand_seeder/"><code>rand_seeder</code></a>.</li>
|
|
</ol>
