Probability

zebra_test::prelude::prop::result

Struct Probability

pub struct Probability(f64);

Expand description

A probability in the range [0.0, 1.0] with a default of 0.5.

Tuple Fields§

§0: f64

Implementations§

impl Probability

pub fn new(prob: f64) -> Probability

Creates a Probability from a f64.

§Panics

Panics if the probability is outside interval [0.0, 1.0].

pub fn with<X>(self, and: X) -> (Probability, X)

Merges self together with some other argument producing a product type expected by some implementations of A: Arbitrary in A::Parameters. This can be more ergonomic to work with and may help type inference.

pub fn lift<X>(self) -> (Probability, X)
where X: Default,

Merges self together with some other argument generated with a default value producing a product type expected by some implementations of A: Arbitrary in A::Parameters. This can be more ergonomic to work with and may help type inference.

Trait Implementations§
