Struct proptest::option::Probability[][src]

pub struct Probability(_);

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

Implementations

impl Probability[src]

pub fn new(prob: f64) -> Self[src]

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) -> (Self, X)[src]

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: Default>(self) -> (Self, X)[src]

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.
