pub struct Beta { /* fields omitted */ }

Deprecated since 0.7.0:

moved to rand_distr crate

The Beta distribution with shape parameters alpha and beta.

Methods

impl Beta

pub fn new(alpha: f64, beta: f64) -> Beta

Construct an object representing the Beta(alpha, beta) distribution.

Panics if shape <= 0 or scale <= 0.

Trait Implementations

impl Clone for Beta

fn clone(&self) -> Beta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Beta

impl Debug for Beta

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

Formats the value using the given formatter.

impl Distribution<f64> for Beta

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> f64

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

Important traits for DistIter<D, R, T>

    D: Distribution<T>,
    R: Rng,  type Item = T;

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