Struct rand::distributions::Weibull

pub struct Weibull { /* fields omitted */ }

Samples floating-point numbers according to the Weibull distribution

Example

use rand::prelude::*;
use rand::distributions::Weibull;

let val: f64 = SmallRng::from_entropy().sample(Weibull::new(1., 10.));
println!("{}", val);

Methods

impl Weibull

pub fn new(scale: f64, shape: f64) -> Weibull

Construct a new Weibull distribution with given scale and shape.

Panics

scale and shape have to be non-zero and positive.
