Struct StandardGeometric

pub struct StandardGeometric;

Samples integers according to the geometric distribution with success probability p = 0.5. This is equivalent to Geometeric::new(0.5), but faster.

See Geometric for the general geometric distribution.

Implemented via iterated [Rng::gen::().leading_zeros()].

Example

use rand::prelude::*;
use rand_distr::StandardGeometric;
 
let v = StandardGeometric.sample(&mut thread_rng());
println!("{} is from a Geometric(0.5) distribution", v);

Trait Implementations

impl Clone for StandardGeometric

fn clone(&self) -> StandardGeometric

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StandardGeometric

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

Formats the value using the given formatter.

impl Distribution<u64> for StandardGeometric

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

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

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.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F
