Struct zipf::ZipfDistribution

pub struct ZipfDistribution { /* fields omitted */ }

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

Methods

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.
