Struct nannou::rand::distributions::Poisson

pub struct Poisson { /* fields omitted */ }

👎 Deprecated since 0.7.0:

moved to rand_distr crate

The Poisson distribution Poisson(lambda).

This distribution has a density function: f(k) = lambda^k * exp(-lambda) / k! for k >= 0.

Implementations

impl Poisson

pub fn new(lambda: f64) -> Poisson

Construct a new Poisson with the given shape parameter lambda. Panics if lambda <= 0.

Trait Implementations

impl Clone for Poisson

pub fn clone(&self) -> Poisson

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Poisson

impl Debug for Poisson

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Distribution<u64> for Poisson

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

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

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

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