Trait rand::distributions::range::SampleRange

pub trait SampleRange: Sized {
    fn construct_range(low: Self, high: Self) -> Range<Self>;
    fn sample_range<R: Rng>(r: &Range<Self>, rng: &mut R) -> Self;
}

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: Rng>(r: &Range<Self>, rng: &mut R) -> Self

Sample a value from the given Range with the given Rng as a source of randomness.
