Struct std::rand::XorShiftRng
[−]
[src]
pub struct XorShiftRng { x: u32, y: u32, z: u32, w: u32, }
rand
): use rand
from crates.io
An Xorshift[1] random number generator.
The Xorshift 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 IsaacRng
or OsRng
.

Methods
impl XorShiftRng
fn new_unseeded() -> XorShiftRng
rand
): use rand
from crates.io
Creates a new XorShiftRng instance which is not seeded.
The initial values of this RNG are constants, so all generators created
by this function will yield the same stream of random numbers. It is
highly recommended that this is created through SeedableRng
instead of
this function
