[−][src]Struct pcg_rand::Pcg32Basic
A low overhead very simple PCG impementation
This is mostly useful for demonstrating how PCG works.
If you want better statistical performance you should use one of the predefined types like
Pcg32
.
Methods
impl Pcg32Basic
[src]
pub fn new_unseeded() -> Pcg32Basic
[src]
Creates a new PCG without specifying a seed.
WARNING: Every PCG created with this method will produce the same
output. In most cases a seeded PCG will be more useful, please check
the references for rand::SeedableRng
and rand::FromEntropy
for
methods to seed a PCG.
