This repository houses a collection of random number generators for use with the Rand project.

All implementations are housed in sub-crates, as follows.

Implements a selection of PCG random number generators.

PCG is a family of simple fast space-efficient statistically good algorithms for random number generation. [Melissa O'Neill, Harvey Mudd College, 2014].

Wherever possible, all sub-crates are no_std compatible, and depend only core and the rand_core library.

All PRNGs feature at minimum a "true values" test comparing output against test vectors provided as part of the specification, as well as "construction" tests testing reproducibility of supported seeding methods.

This parent crate includes benchmarks of all sub-crates, making benchmarking as simple as cargo +nightly bench.
