[][src]Struct rand::rngs::StdRng

pub struct 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 is the ChaCha block cipher with either 20 or 12 rounds (see the stdrng_* feature flags, documented in the README). This may change as new evidence of cipher security and performance becomes available.

The algorithm is deterministic but should not be considered reproducible due to dependence on configuration and possible replacement in future library versions. For a secure reproducible generator, we recommend use of the rand_chacha crate directly.
