Module view 

Zero-copy read-only index view (VecqView) — issue #25.

Parse the v1.2/v1.3/v1.4/v1.5 on-disk layout without copying codes or scales, so an index can be served straight from a memory map. Any owner works: memmap2::Mmap, &[u8], Box<[u8]>, Vec<u8> — the view only needs &[u8].

Scoring goes through the same shared kernel dispatch as [crate::store:: VecqIndex] and the layout is identical, so a view and a loaded index over the same bytes return bit-identical results (tested).

Views are always dense: to_bytes drops tombstones before writing, and the keyed API layer is in-memory by design (#10/#16) — not available on a borrowed, read-only slice.

Structs

VecqView

Read-only, zero-copy view over an index file (or any bytes in the same layout). Generic over the byte owner’s lifetime.

ViewQuery

Prepared query for a VecqView (same fields and semantics as the index-side [PreparedQuery], freed from its lifetime by cloning the small rotated-query buffer).
