# Struct rand::XorShiftRng
[−]
[src]

pub struct XorShiftRng { // some fields omitted }

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`

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
