PackVerifyStat: Per-object statistics for one entry of a verified pack, in the shape git verify-pack -v reports.
PackVerifyStats: Result of PackFile::verify_pack_stats: per-object stats in pack offset order plus the pack’s trailing checksum.
PackWrite
PackWriteOptions: Options controlling sliding-window delta selection during pack generation.
RepackPolicy

DEFAULT_PACK_DEPTH: Default maximum delta chain depth used by PackFile::write_packed.
DEFAULT_PACK_WINDOW: Default sliding-window size used by PackFile::write_packed.

HeaderTypeCache: Memo of pack offset -> resolved header (end-of-chain type, result size) for the cat-file --batch-check header fast path.
PackDeltaCache: A cache of objects already decoded from one specific pack, keyed by the in-pack byte offset at which each object’s entry begins.
PackIndexByteSource

pack_order_index_positions: The .rev table for a pack: index positions (the rank of each object in the oid-sorted .idx) listed in pack order (ascending pack offset), as upstream write_rev_file lays them out. Accepts entries in any order; the result feeds PackReverseIndex::write.
read_object_at_arc: Decode the single object stored at byte offset within pack_bytes, reading only that object and its delta-base chain instead of parsing the whole pack.
read_object_at_with_cache_arc: Like read_object_at_arc, but reuses already-decoded objects from cache (keyed by in-pack offset) and records every object it decodes.
read_object_header_at: The object type and final (inflated) size of the entry at offset, without materializing the object body — git’s cat-file --batch-check fast path.
read_object_header_at_with_cache: Like read_object_header_at but threads a caller-owned HeaderTypeCache through the read so (a) the ofs-delta chain’s end-of-chain type is resolved at most once per chain and (b) a repeated lookup of the same offset returns from the memo without re-inflating (sley#26). The cache is keyed by in-pack offset, so it must be scoped to a single pack’s bytes by the caller.
write_bitmap: Convenience wrapper that builds a .bitmap file in one call.
