Detailed Description

template<typename... Iters>
struct jh::ranges::zip_iterator< Iters >

Iterator type for jh::ranges::zip_view.

zip_iterator traverses multiple input ranges in lockstep, dereferencing into a zip_reference_proxy that aggregates element references from each underlying range.

Each iterator maintains a tuple of underlying iterators (Iters...) and advances all of them together. Comparison against a corresponding zip_sentinel terminates iteration when any of the underlying iterators reaches its end, ensuring short-circuit termination on the shortest range.

Dereferencing (operator*) applies tuple_transform to dereference each underlying iterator, wrapping lvalue results with std::reference_wrapper when necessary via detail::wrap_element().

Template Parameters

Iters

The iterator types for the zipped ranges.

Note

This type is intentionally defined outside of zip_view to maintain independent template deduction and suppress clang-tidy "unused type" warnings via [[maybe_unused]].
