Struct rand_distr::UnitCircle

source ·
pub struct UnitCircle;
Expand description

Samples uniformly from the edge of the unit circle in two dimensions.

Implemented via a method by von Neumann1.

Example

use rand_distr::{UnitCircle, Distribution};

let v: [f64; 2] = UnitCircle.sample(&mut rand::thread_rng());
println!("{:?} is from the unit circle.", v)
