Struct rand_xorshift::XorShiftRng [−][src]
pub struct XorShiftRng { /* fields omitted */ }
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
.
