Struct nannou_core::rand::rngs::mock::StepRng [−][src]
pub struct StepRng { /* fields omitted */ }
Expand description
A simple implementation of RngCore
for testing purposes.
This generates an arithmetic sequence (i.e. adds a constant each step)
over a u64
number, using wrapping arithmetic. If the increment is 0
the generator yields a constant.
use rand::Rng;
use rand::rngs::mock::StepRng;
let mut my_rng = StepRng::new(2, 1);
let sample: [u64; 3] = my_rng.gen();
assert_eq!(sample, [2, 3, 4]);

Convert into T. The resulting color might be invalid in its color space Read more
Convert into T, returning ok if the color is inside of its defined range,
otherwise an OutOfBounds
error is returned which contains the unclamped color. Read more

Return a bool with a probability p
of being true. Read more
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
