Struct rdeck::SliceDeck

pub struct SliceDeck<'a, R: Rng, T> { /* private fields */ }

a Deck that randomly draws elements from a slice.

note that this works by randomly picking an index of the slice, so it is possible to draw two card with equal value if (and only if) the slice contains two elements of equal value.
