Struct std::random::Bernoulli

Bernoulli distribution. Returns true with probability p and false with probability 1 - p.

Example

use std::random::{thread_rng, Bernoulli};

let dist = Bernoulli::new(0.5);
if dist.sample(thread_rng()) {
    println!("Heads");
} else {
    println!("Tails");
}

Methods

• fn new(p: f64) -> Bernoulli

  source

  Creates a new Bernoulli distribution with the given probability.

  Panics if p is not in the range [0, 1].

• fn sample<R>(self: &Bernoulli, rng: &mut R) -> bool

  R: Rng<R>

  source

  Samples a distribution using a provided random number generator.

Mixins

• mixin<R> Distribution<Bernoulli, bool, R>

  R: Rng<R>

• fn sample_iter(self: &Self, rng: &mut R) -> DistIterator<Self, T, R>

  source

  Raturns an iterator producing an infinite stream of values sampled from the distribution.

  Example

  use std::random::{thread_rng, UniformInteger};
  
  let dist = UniformInteger::new(0..=5);
  
  // Prints 10 random numbers between 0 and 5 inclusive
  for i in dist.sample_iter(thread_rng()).take(10) {
      println!("{}", i);
  }
