Struct rand::distributions::Binomial

pub struct Binomial { /* fields omitted */ }

Deprecated since 0.7.0:

moved to rand_distr crate

The binomial distribution Binomial(n, p).

This distribution has density function: f(k) = n!/(k! (n-k)!) p^k (1-p)^(n-k) for k >= 0.

Methods

impl Binomial

pub fn new(n: u64, p: f64) -> Binomial

Construct a new Binomial with the given shape parameters n (number of trials) and p (probability of success).

Panics if p < 0 or p > 1.

Trait Implementations

impl Clone for Binomial

fn clone(&self) -> Binomial

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Binomial

impl Debug for Binomial

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Distribution<u64> for Binomial

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> u64

Generate a random value of T, using rng as the source of randomness.

Important traits for DistIter<D, R, T>

impl<D, R, T> Iterator for DistIter<D, R, T> where
    D: Distribution<T>,
    R: Rng,  type Item = T;

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T> where
    R: Rng,
    Self: Sized, 

Create an iterator that generates random values of T, using rng as the source of randomness.
