Module sparse 

Sparse iterator-backed ALTREP data adaptors with skipping support.

Provides SparseIterState<I, T> which uses Iterator::nth() to skip elements efficiently, and data-adaptor types for each ALTREP family.

See the super module docs for how to expose these adaptors to R (wrap in a #[derive(Altrep*)] + #[altrep(manual)] struct).
