Detailed Description

template<typename Seq>
class jh::ranges::range_adaptor< Seq >

Lightweight adapter that exposes any sequence as a standard range.

Wraps a duck-typed sequence so that it models std::ranges::range.

• begin() returns a completed_iterator wrapping the sequence's iterator.
• end() is forwarded directly from the underlying sequence.

Enables generic algorithms and range-based for loops to work with any object satisfying jh::concepts::sequence, regardless of whether it defines STL-compatible iterator traits.

Template Parameters

Seq	Sequence-like type satisfying jh::concepts::sequence.

Note

If the sequence's begin() and end() types are identical, the adaptor transparently returns a completed_iterator for both. This allows the resulting view to model std::ranges::common_range, enabling tighter interoperability with standard range algorithms.
