| <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>Pcg64</code> aka <code>Lcg128Xsl64</code>, officially known as <code>pcg64</code>, a general |
| purpose RNG. This is a good choice on 64-bit CPUs.</li> |
| <li><code>Pcg64Mcg</code> aka <code>Mcg128Xsl64</code>, officially known as <code>pcg64_fast</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.</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> |
