Trait relearn::spaces::SampleSpace

source · [−]

pub trait SampleSpace: NonEmptySpace {
    fn sample(&self, rng: &mut dyn RngCore) -> Self::Element;
}

Expand description

A space from which samples can be drawn.

No particular distribution is specified but the distribution:

must have support equal to the entire space, and
should be some form of reasonable “standard” distribution for the space.

Note

This re-implements sample method of Distribution rather than set Distribution<Self::Element> as a super-trait so that SampleSpace is object-safe since

Distribution<T> is not object-safe, and even if it was,
generic super traits using <Self::AssocType> are not object safe due to a bug / issue: https://github.com/rust-lang/rust/issues/40533.
