Struct sample_test::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.

Implementations§
source§impl Random
impl Random
pub fn arbitrary<T>(&self) -> Twhere
T: Arbitrary,
pub fn from_seed(seed: u64) -> Random
sourcepub fn choose<'a, T>(&mut self, slice: &'a [T]) -> Option<&'a T>
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.
