Data Fields
uint32_t	object_id
	Cached object id.
uint64_t	offset
	Frame-aligned byte offset of the cached page.

Detailed Description

The (object_id, frame-aligned offset) key the page cache hashes on.

Treat as private; the cache owns the contents. Provide an array of frame_count of these as the engine's key storage (parallel to the ra8_vmem_frame_t metadata). ra8_vmem always zero-fills a key before use, so the struct's padding never carries indeterminate bytes into the byte-wise key comparison.
