Reproducible, robust and (last but not least) fast pseudorandomness.
This crate implements the chacha8rand specification, originally designed
for Go's math/rand/v2 package. The language-independent specification and test
vector helps with long-term reproducibility and interoperability. Building on
the ChaCha8 stream cipher ensures high statistical quality and removes entire
classes of "you're holding it wrong"-style problems that lead to sub-par output.
It's also carefully designed and implemented (using SIMD instructions when
available) to be so fast that it shouldn't ever be a bottleneck. However, it
should not be used for cryptography.
