Struct Probability 

pub struct Probability(/* private fields */);

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

Implementations

impl Probability

pub fn new(prob: f64) -> Self

Creates a Probability from a f64.

Safety

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

pub fn with<X>(self, and: X) -> HCons<Self, HCons<X, HNil>>

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

pub fn lift<X: Default>(self) -> HCons<Self, HCons<X, HNil>>

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

Trait Implementations

impl<'a> Arbitrary<'a> for Probability

type ValueTree = <<Probability as Arbitrary<'a>>::Strategy as Strategy>::Value

The type of ValueTree used for Self’s Strategy.

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<Range<f64>, FromMapper<<<Range<f64> as Strategy>::Value as ValueTree>::Value, Probability>>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_args: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for Probability

fn clone(&self) -> Probability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Probability

impl Debug for Probability

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

Formats the value using the given formatter.

impl Default for Probability

fn default() -> Self

Returns the “default value” for a type.

impl From<Probability> for f64

fn from(original: Probability) -> f64

Converts to this type from the input type.

impl From<f64> for Probability

fn from(prob: f64) -> Self

Creates a Probability from a f64.

Safety

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

impl Generic for Probability

Available on crate feature frunk only.

fn into(self) -> Self::Repr

Converts the Probability into an f64.

fn from(r: Self::Repr) -> Self

Creates a Probability from a f64.

Safety

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

type Repr = f64

The generic representation type

fn convert_from<A>(a: A) -> Self

where A: Generic<Repr = Self::Repr>, Self: Sized,

From one type to another using a type with a compatible generic representation

impl PartialEq for Probability

fn eq(&self, other: &Probability) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
