Trait rand::SeedableRng
[−]
[src]
pub trait SeedableRng<Seed>: Rng { fn reseed(&mut self, Seed); fn from_seed(seed: Seed) -> Self; }
A random number generator that can be explicitly seeded to produce the same stream of randomness multiple times.
Required Methods
fn reseed(&mut self, Seed)
Reseed an RNG with the given seed.
Example
use rand::{Rng, SeedableRng, StdRng}; let seed: &[_] = &[1, 2, 3, 4]; let mut rng: StdRng = SeedableRng::from_seed(seed); println!("{}", rng.gen::<f64>()); rng.reseed(&[5, 6, 7, 8]); println!("{}", rng.gen::<f64>());
fn from_seed(seed: Seed) -> Self
Create a new RNG with the given seed.
Example
use rand::{Rng, SeedableRng, StdRng}; let seed: &[_] = &[1, 2, 3, 4]; let mut rng: StdRng = SeedableRng::from_seed(seed); println!("{}", rng.gen::<f64>());
