Module state 

Core iterator-backed ALTREP data adaptors.

Provides IterState<I, T> (the shared lazy-caching state machine) and data-adaptor types for the integer/real/logical/raw ALTREP families: IterIntData, IterRealData, IterLogicalData, IterRawData. The string/list/complex adaptors (IterStringData, IterListData, IterComplexData) live in super::coerce.

See the super module docs for how to expose these adaptors to R: they implement only the data-level traits (AltrepLen + Alt*Data) and must be wrapped in a concrete #[derive(Altrep*)] + #[altrep(manual)] struct to back a live ALTREP vector.
