Struct sample_std::Random

source ·
pub struct Random {
    pub rng: SmallRng,
}
Expand description

Random represents a PRNG.

It is a reimplementation of quickcheck::Gen, which does not export the methods we need to properly generate random values.

It is unspecified whether this is a secure RNG or not. Therefore, callers should assume it is insecure.

Fields§

§rng: SmallRng

Implementations§

source§

impl Random

source

pub fn arbitrary<T: Arbitrary>(&self) -> T

source

pub fn new() -> Self

Returns a new Random instance.

source

pub fn from_seed(seed: u64) -> Self

source

pub fn choose<'a, T>(&mut self, slice: &'a [T]) -> Option<&'a T>

Choose among the possible alternatives in the slice given. If the slice is empty, then None is returned. Otherwise, a non-None value is guaranteed to be returned.

source

pub fn gen<T>(&mut self) -> Twhere Standard: Distribution<T>,

source

pub fn gen_range<T, R>(&mut self, range: R) -> Twhere T: SampleUniform, R: SampleRange<T>,
