Struct rand::distributions::exponential::Exp

pub struct Exp {
    // some fields omitted
}

Unstable (rand)

: use rand from crates.io

The exponential distribution Exp(lambda).

This distribution has density function: f(x) = lambda * exp(-lambda * x) for x > 0.

Methods

impl Exp

fn new(lambda: f64) -> Exp

Unstable (rand)

: use rand from crates.io

Construct a new Exp with the given shape parameter lambda. Panics if lambda <= 0.

Trait Implementations

impl Sample<f64> for Exp

fn sample<R: Rng>(&mut self, rng: &mut R) -> f64

Generate a random value of Support, using rng as the source of randomness.

impl IndependentSample<f64> for Exp

fn ind_sample<R: Rng>(&self, rng: &mut R) -> f64

Generate a random value.

Derived Implementations

impl Clone for Exp

fn clone(&self) -> Exp

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
