Struct zipf::ZipfDistribution

pub struct ZipfDistribution { /* private fields */ }

Random number generator that generates Zipf-distributed random numbers using rejection inversion.

Implementations

impl ZipfDistribution

pub fn new(num_elements: usize, exponent: f64) -> Result<Self, ()>

Creates a new Zipf-distributed random number generator.

Note that both the number of elements and the exponent must be greater than 0.

Trait Implementations

impl Clone for ZipfDistribution

fn clone(&self) -> ZipfDistribution

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ZipfDistribution

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

Formats the value using the given formatter.

impl Distribution<usize> for ZipfDistribution

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> usize

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R, 'a>(&'a self, rng: &'a mut R) -> DistIter<'a, Self, R, T>where
    Self: Sized,
    R: Rng,

Create an iterator that generates random values of T, using rng as the source of randomness.
