|
||
<p>This is a native Rust implementation of a small selection of PCG generators.
|
||
The primary goal of this crate is simple, minimal, well-tested code; in
|
||
other words it is explicitly not a goal to re-implement all of PCG.</p>
|
||
<p>This crate provides:</p>
|
||
<ul>
|
||
<li><code>Pcg32</code> aka <code>Lcg64Xsh32</code>, officially known as <code>pcg32</code>, a general
|
||
purpose RNG. This is a good choice on both 32-bit and 64-bit CPUs
|
||
(for 32-bit output).</li>
|
||
<li><code>Pcg64Mcg</code> aka <code>Mcg128Xsl64</code>, officially known as <code>mcg_xsl_rr_128_64</code>,
|
||
a general purpose RNG using 128-bit multiplications. This has poor
|
||
performance on 32-bit CPUs but is a good choice on 64-bit CPUs for
|
||
both 32-bit and 64-bit output. (Note: this RNG is only available using
|
||
Rust 1.26 or later.)</li>
|
||
</ul>
|
||
<p>Both of these use 16 bytes of state and 128-bit seeds, and are considered
|
||
value-stable (i.e. any change affecting the output given a fixed seed would
|
||
be considered a breaking change to the crate).</p>
