Struct zipf::ZipfDistribution
[−]
[src]
pub struct ZipfDistribution<R> { /* fields omitted */ }
Random number generator that generates Zipf-distributed random numbers using rejection inversion.
Methods
impl<R: Rng> ZipfDistribution<R>
[src]
fn new(sampler: R, 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.
