rand_xorshift

Struct XorShiftRng

source
pub struct XorShiftRng { /* private fields */ }
Expand description

An Xorshift random number generator.

The Xorshift1 algorithm is not suitable for cryptographic purposes but is very fast. If you do not know for sure that it fits your requirements, use a more secure one such as StdRng or OsRng.
