Source§fn gen_range<T, B1, B2>(&mut self, low: B1, high: B2) -> T
fn gen_range<T, B1, B2>(&mut self, low: B1, high: B2) -> T
Generate a random value in the range [
low, high), i.e. inclusive of
low and exclusive of high. Read moreSource§fn sample<T, D>(&mut self, distr: D) -> Twhere
D: Distribution<T>,
fn sample<T, D>(&mut self, distr: D) -> Twhere
D: Distribution<T>,
Sample a new value, using the given distribution. Read more

fn sample_iter<'a, T, D>(&'a mut self, distr: &'a D) -> DistIter<'a, D, Self, T>where
D: Distribution<T>,
Self: Sized,
Create an iterator that generates values using the given distribution. Read more

T: AsByteSliceMut + ?Sized,
fn fill<T>(&mut self, dest: &mut T)where
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 moreSource§fn try_fill<T>(&mut self, dest: &mut T) -> Result<(), Error>where

fn try_fill<T>(&mut self, dest: &mut T) -> Result<(), Error>where
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 moreSource§fn gen_bool(&mut self, p: f64) -> bool
fn gen_bool(&mut self, p: f64) -> bool
Return a bool with a probability
p of being true. Read moreSource§fn gen_ratio(&mut self, numerator: u32, denominator: u32) -> bool
fn gen_ratio(&mut self, numerator: u32, denominator: u32) -> bool
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 moreSource§fn choose<'a, T>(&mut self, values: &'a [T]) -> Option<&'a T>
fn choose<'a, T>(&mut self, values: &'a [T]) -> Option<&'a T>
👎Deprecated since 0.6.0: use SliceRandom::choose instead
Return a random element from
values. Read more
