Struct Pcg64

pub struct Pcg64 { /* private fields */ }

An instance of the Pcg64 random number generator. Seeded from the system entropy generator when available. This generator is NOT cryptographically secure.

Implementations

impl Pcg64

pub fn new() -> Self

Create a new Pcg64 instance, seeding from the system’s default source of entropy.

pub const fn new_seed(seed: u128) -> Self

Create a new Pcg64 instance, using a provided seed.
