Struct rand_xorshift::XorShiftRng

[+] Show declaration

pub struct XorShiftRng { /* fields omitted */ }

[−] 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.
