Struct rand_distr::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 copy 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

Formats the value using the given formatter.

impl<F: Float + SampleUniform> Distribution<[F; 2]> for UnitDisc

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

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, 

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, 

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