PageSlot and PageRef — DataCap page storage.

Each page is owned by the DataCap that holds it. Sharing across DataCap CoW clones is done via PageRef, a refcounted handle over PageBytes backed by the global allocator. The cache subsystem doesn’t index pages by hash — pages aren’t first-class caps. They’re internal to the DataCap layer.

Structs

An archived PageBytes

PageBytes

One page’s bytes plus its precomputed content hash.

The resolver for an archived PageBytes

Enums

ArchivedPageSlot

An archived PageSlot

PageSlot

Sparse representation of a paged DataCap’s pages. Empty is the canonical zero page; Loaded holds a refcounted byte slab; Missing records the page’s content hash so a host callback can later resolve it (V1: never observed — we always pre-publish).

Type Aliases

PageRef

Refcounted handle to a PageBytes allocated by the global allocator. Plain std::sync::Arc alias for cap-layer readability.
