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

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

fn choose<T, 'a>(&mut self, values: &'a [T]) -> Option<&'a T>
👎Deprecated since 0.6.0: use SliceRandom::choose instead
Return a random element from
