Struct StandardGeometric

pub struct StandardGeometric;

The standard geometric distribution Geometric(0.5).

This is equivalent to Geometric::new(0.5), but faster.

See Geometric for the general geometric distribution.

Plot

The following plot illustrates the standard geometric distribution.

Example

use rand::prelude::*;
use rand_distr::StandardGeometric;

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

Notes

Implemented via iterated Rng::gen::<u64>().leading_zeros().
