//! The PCG random number generators.
//!
//! 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.
//!
//! This crate provides:
//!
//! -   `Pcg32` aka `Lcg64Xsh32`, officially known as `pcg32`, a general
//!     purpose RNG. This is a good choice on both 32-bit and 64-bit CPUs
//!     (for 32-bit output).
//! -   `Pcg64` aka `Lcg128Xsl64`, officially known as `pcg64`, a general
//!     purpose RNG. This is a good choice on 64-bit CPUs.
//! -   `Pcg64Mcg` aka `Mcg128Xsl64`, officially known as `pcg64_fast`,
//!     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.
//!
//! 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).
