pub trait SampleRange {
    fn construct_range(low: Self, high: Self) -> Range<Self>;
    fn sample_range<R>(r: &Range<Self>, rng: &mut R) -> Self
    where
        R: Rng;
}The helper trait for types that have a sensible way to sample
uniformly between two values. This should not be used directly,
and is only to facilitate Range.
Required Methods
fn construct_range(low: Self, high: Self) -> Range<Self>
Construct the Range object that sample_range
requires. This should not ever be called directly, only via
Range::new, which will check that low < high, so this
function doesn't have to repeat the check.
fn sample_range<R>(r: &Range<Self>, rng: &mut R) -> Self where
    R: Rng, 
R: Rng,
Sample a value from the given Range with the given Rng as
a source of randomness.
