Struct rand_simple::Frechet

pub struct Frechet { /* private fields */ }

Frechet Distribution

Example

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

// Modifying the parameters of the random variable
let shape: f64 = 2_f64;
let scale: f64 = 1.5_f64;
let result: Result<(f64, f64), &str> = frechet.try_set_params(shape, scale);
assert_eq!(format!("{frechet}"), "Fr(Shape parameter, Scale parameter) = Fr(2, 1.5)");

Implementations

impl Frechet

pub fn new(_seed: u32) -> Self

Constructor for creating a new instance of the Frechet distribution.

Arguments

• _seed - The seed for initializing the random number generator.

Returns

A new instance of the Frechet distribution with default parameters (shape = 1, scale = 1).

pub fn sample(&mut self) -> f64

Generate a random number.

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

Try to set the parameters of the random variable.

• shape - Shape parameter.
• scale - Scale parameter.

Trait Implementations

impl Display for Frechet

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

Formatter for displaying the Frechet distribution parameters.
