Struct rand_distr::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);
