Struct rand_simple::Weibull

pub struct Weibull { /* private fields */ }

Weibull Distribution

Example

let mut weibull = rand_simple::Weibull::new(1192u32);
assert_eq!(format!("{weibull}"), "Weibull(Shape parameter, Scale parameter) = Weibull(1, 1)");

// If you want to change the parameters of the random variable
let shape: f64 = 2f64;
let scale: f64 = 1.5f64;
let result: Result<(f64, f64), &str> = weibull.try_set_params(shape, scale);
assert_eq!(format!("{weibull}"), "Weibull(Shape parameter, Scale parameter) = Weibull(2, 1.5)");

Implementations

impl Weibull

pub fn new(_seed: u32) -> Self

Constructor for the Weibull random number generator.

• _seed - Seed for the random number generator.

pub fn sample(&mut self) -> f64

Computes a random number. Returns a random number sampled from the Weibull distribution with the specified shape and scale parameters.

pub fn try_set_params( &mut self, shape: f64, scale: f64 ) -> Result<(f64, f64), &str>

Attempts to set the parameters of the probability variable.

• shape - Shape parameter.
• scale - Scale parameter. Returns a Result containing a tuple (shape, scale) on success, or an error message if the parameters are invalid.

Trait Implementations

impl Display for Weibull

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

Implements the Display trait for the Weibull struct. This allows the struct to be formatted and displayed using macros like println! It displays information about the scale parameter.
