Struct Poisson 

pub struct Poisson {
    pub mean: f64,
}

Poisson with mean lambda.

Fields

mean: f64

Mean parameter λ. Must be > 0.

Trait Implementations

impl Clone for Poisson

fn clone(&self) -> Poisson

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Poisson

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

Formats the value using the given formatter.

impl Distribution<u64> for Poisson

fn sample(&self, rng: &mut Random) -> u64

Draws one sample from self using rng.

fn samples<'a>(&'a self, rng: &'a mut Random) -> Iter<'a, Self, T>

where Self: Sized,

Returns an iterator that calls sample repeatedly. Useful for take(n).collect()-style consumption.
