[−][src]Struct quickcheck::StdGen

pub struct StdGen<R> { /* fields omitted */ }

StdGen is the default implementation of Gen.

Values of type StdGen can be created with the gen function in this crate.

Methods

impl<R: RngCore> StdGen<R>[src]

pub fn new(rng: R, size: usize) -> StdGen<R>[src]

Returns a StdGen with the given configuration using any random number generator.

The size parameter controls the size of random values generated. For example, it specifies the maximum length of a randomly generated vector and also will specify the maximum magnitude of a randomly generated number.

fn gen<T>(&mut self) -> T where
    Standard: Distribution<T>, [src]

Return a random value supporting the [Standard] distribution. Read more

fn gen_range<T, B1, B2>(&mut self, low: B1, high: B2) -> T where
    B1: SampleBorrow<T>,
    B2: SampleBorrow<T>,
    T: SampleUniform, [src]

Generate a random value in the range [low, high), i.e. inclusive of low and exclusive of high. Read more

fn sample<T, D>(&mut self, distr: D) -> T where
    D: Distribution<T>, [src]

Sample a new value, using the given distribution. Read more

fn sample_iter<T, D>(&'a mut self, distr: &'a D) -> DistIter<'a, D, Self, T> where
    D: Distribution<T>, [src]

Create an iterator that generates values using the given distribution. Read more

fn fill<T>(&mut self, dest: &mut T) where
    T: AsByteSliceMut + ?Sized, [src]

Fill dest entirely with random bytes (uniform value distribution), where dest is any type supporting [AsByteSliceMut], namely slices and arrays over primitive integer types (i8, i16, u32, etc.). Read more

fn try_fill<T>(&mut self, dest: &mut T) -> Result<(), Error> where
    T: AsByteSliceMut + ?Sized, [src]

Fill dest entirely with random bytes (uniform value distribution), where dest is any type supporting [AsByteSliceMut], namely slices and arrays over primitive integer types (i8, i16, u32, etc.). Read more

fn gen_bool(&mut self, p: f64) -> bool[src]

Return a bool with a probability p of being true. Read more

fn gen_ratio(&mut self, numerator: u32, denominator: u32) -> bool[src]

Return a bool with a probability of numerator/denominator of being true. I.e. gen_ratio(2, 3) has chance of 2 in 3, or about 67%, of returning true. If numerator == denominator, then the returned value is guaranteed to be true. If numerator == 0, then the returned value is guaranteed to be false. Read more
