Data Structures

Here are the data structures with brief descriptions:

Caaru_flac_ctx
Caaru_options	Parsed user-specified tunables controlling compression, deduplication, hashing and DDT geometry
Caaruformat_context	Master context representing an open or in‑creation Aaru image
CAaruHeader	Version 1 container header placed at offset 0 for legacy / initial format
CAaruHeaderV2	Version 2 container header with GUID, alignment shifts, and feature negotiation bitmaps
CAaruMetadataJsonBlockHeader	Header for an Aaru metadata JSON block (identifier == BlockType::AaruMetadataJsonBlock)
Cblockhash_ctx
CBlockHeader	Header preceding the compressed data payload of a data block (BlockType::DataBlock)
CCacheEntry	Single hash entry in the in-memory cache
CCacheHeader	Cache top-level descriptor encapsulating the hash table root and capacity limit
CCdEccContext	Lookup tables and state for Compact Disc EDC/ECC (P/Q) regeneration / verification
CChecksumEntry	Per-checksum metadata immediately followed by the digest / signature bytes
CChecksumHeader	Header that precedes the sequence of checksum entries for a checksum block
CChecksums	Collected whole‑image checksums / hashes present in a checksum block
CCicmMetadataBlock	Header for a CICM XML metadata block (identifier == BlockType::CicmBlock)
Ccrc64_ctx	Minimal ECMA-182 CRC64 incremental state container (running value only)
CDdtHeader	Header preceding a version 1 (flat) deduplication table body
CDdtHeader2	Header preceding a version 2 hierarchical deduplication table
CDumpExtent	Inclusive [start,end] logical sector range contributed by a single hardware environment
CDumpHardwareEntriesWithData	In-memory representation of a dump hardware entry plus decoded variable-length fields & extents
CDumpHardwareEntry	Per-environment length table describing subsequent UTF-8 strings and optional extent array
CDumpHardwareHeader	Header that precedes a sequence of dump hardware entries and their variable-length payload
CGeometryBlockHeader	Legacy CHS style logical geometry metadata (BlockType::GeometryBlock)
Chash_map_t	Minimal open-addressing hash map for 64-bit key/value pairs used in deduplication lookup
CImageInfo	High-level summary of an opened Aaru image containing metadata and media characteristics
CIndexEntry	Single index entry describing a block's type, (optional) data classification, and file offset
CIndexHeader	Index header (version 1) for legacy images (identifier == IndexBlock)
CIndexHeader2	Index header (version 2) with 64‑bit entry counter (identifier == IndexBlock2)
CIndexHeader3	Index header (version 3) adding hierarchical chaining (identifier == IndexBlock3)
Ckv_pair_t	Single key/value slot used internally by the open-addressing hash map
Cmd5_ctx

CTapeFileHeader	Header for a tape file metadata block containing file layout information
CTapePartitionEntry	Describes a single physical partition on a tape medium
CTapePartitionHashEntry
CTapePartitionHeader	Header for a tape partition metadata block containing partition layout information
CTrackEntry	Single optical disc track descriptor (sequence, type, LBAs, session, ISRC, flags)
CTracksHeader	Header for an optical tracks block listing track entries
