| <span class="doccomment">//!</span> |
| <span class="doccomment">//! This is a native Rust implementation of a small selection of PCG generators.</span> |
| <span class="doccomment">//! The primary goal of this crate is simple, minimal, well-tested code; in</span> |
| <span class="doccomment">//! other words it is explicitly not a goal to re-implement all of PCG.</span> |
| <span class="doccomment">//!</span> |
| <span class="doccomment">//! This crate provides:</span> |
| <span class="doccomment">//!</span> |
| <span class="doccomment">//! - `Pcg32` aka `Lcg64Xsh32`, officially known as `pcg32`, a general</span> |
| <span class="doccomment">//! purpose RNG. This is a good choice on both 32-bit and 64-bit CPUs</span> |
| <span class="doccomment">//! (for 32-bit output).</span> |
| <span class="doccomment">//! - `Pcg64` aka `Lcg128Xsl64`, officially known as `pcg64`, a general</span> |
| <span class="doccomment">//! purpose RNG. This is a good choice on 64-bit CPUs.</span> |
| <span class="doccomment">//! - `Pcg64Mcg` aka `Mcg128Xsl64`, officially known as `pcg64_fast`,</span> |
| <span class="doccomment">//! a general purpose RNG using 128-bit multiplications. This has poor</span> |
| <span class="doccomment">//! performance on 32-bit CPUs but is a good choice on 64-bit CPUs for</span> |
| <span class="doccomment">//! both 32-bit and 64-bit output.</span> |
| <span class="doccomment">//!</span> |
| <span class="doccomment">//! Both of these use 16 bytes of state and 128-bit seeds, and are considered</span> |
| <span class="doccomment">//! value-stable (i.e. any change affecting the output given a fixed seed would</span> |
| <span class="doccomment">//! be considered a breaking change to the crate).</span> |
