Struct UnitDisc 

pub struct UnitDisc;

Samples uniformly from the unit disc in two dimensions.

Implemented via rejection sampling.

Example

use rand_distr::{UnitDisc, Distribution};

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

Trait Implementations

impl Clone for UnitDisc

fn clone(&self) -> UnitDisc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnitDisc

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

Formats the value using the given formatter.

impl<F> Distribution<[F; 2]> for UnitDisc

where F: Float + SampleUniform,

fn sample<R>(&self, rng: &mut R) -> [F; 2]

where R: Rng + ?Sized,

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
