[−][src]Struct quickcheck::StdThreadGen
StdThreadGen is an RNG in thread-local memory.
This is the default RNG used by quickcheck.
Methods
impl StdThreadGen[src]
pub fn new(size: usize) -> StdThreadGen[src]
Returns a new thread-local RNG.
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.

B1: SampleBorrow<T>,
B2: SampleBorrow<T>,
T: SampleUniform, [src]
B1: SampleBorrow<T>,
B2: SampleBorrow<T>,
T: SampleUniform,
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]
D: Distribution<T>,
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]
D: Distribution<T>,
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]
T: AsByteSliceMut + ?Sized,
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]
T: AsByteSliceMut + ?Sized,
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
