[−][src]Struct peroxide::macros::r_macro::StdRng
The standard RNG. The PRNG algorithm in StdRng is chosen to be efficient
on the current platform, to be statistically strong and unpredictable
(meaning a cryptographically secure PRNG).
The current algorithm used on all platforms is HC-128, found in the rand_hc crate.
Reproducibility of output from this generator is however not required, thus
future library versions may use a different internal generator with
different output. Further, this generator may not be portable and can
produce different output depending on the architecture. If you require
reproducible output, use a named RNG, for example ChaChaRng from the
rand_chacha crate.
