impl<R> Rng for R where
R: RngCore + ?Sized, [src]
R: RngCore + ?Sized,
fn gen<T>(&mut self) -> T where
Standard: Distribution<T>, [src]
Standard: Distribution<T>,
Return a random value supporting the [Standard] distribution. Read more
fn gen_range<T: SampleUniform, B1, B2>(&mut self, low: B1, high: B2) -> T where
B1: SampleBorrow<T> + Sized,
B2: SampleBorrow<T> + Sized, [src]
B1: SampleBorrow<T> + Sized,
B2: SampleBorrow<T> + Sized,
Generate a random value in the range [low, high), i.e. inclusive of low and exclusive of high. Read more

) -> DistIter<'a, D, Self, T> where
Self: Sized, [src]
&'a mut self,

) -> DistIter<'a, D, Self, T> where

Create an iterator that generates values using the given distribution. Read more
fn fill<T: AsByteSliceMut + ?Sized>(&mut self, dest: &mut T)[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: AsByteSliceMut + ?Sized>(
&mut self,
dest: &mut T
) -> Result<(), Error>[src]
&mut self,
dest: &mut T
) -> Result<(), Error>
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
fn choose<'a, T>(&mut self, values: &'a [T]) -> Option<&'a T>[src]
use SliceRandom::choose instead
Return a random element from values. Read more
fn choose_mut<'a, T>(&mut self, values: &'a mut [T]) -> Option<&'a mut T>[src]
use SliceRandom::choose_mut instead
Return a mutable pointer to a random element from values. Read more
fn shuffle<T>(&mut self, values: &mut [T])[src]
use SliceRandom::shuffle instead
Shuffle a mutable slice in place. Read more
