Implementations

impl Reader

pub fn open(path: &Path) -> Result<Self>

pub fn superblock(&self) -> &Superblock

pub fn sections(&self) -> &[SectionEntry]

pub fn tracks(&self) -> &[TrackRecord]

pub fn dict(&self) -> &[u32]

pub fn chunks(&self) -> &[ChunkRecord]

pub fn segments(&self) -> &[SegmentRecord]

pub fn meta(&self) -> &[(String, String)]

pub fn integrity(&self) -> &Integrity

pub fn track(&self, track_id: u32) -> Result<&TrackRecord>

pub fn segments_for_track(&self, track_id: u32) -> Vec<&SegmentRecord>

Segments of one track, ordered by presentation time.

pub fn read_chunk_stored(&mut self, index: u32) -> Result<(Vec<u8>, u32, u32)>

Read one chunk payload exactly as stored (possibly zstd-compressed), without decompressing or verifying. Returns (stored bytes, flags, len_raw). Intended for wire passthrough: the receiver decompresses and verifies the BLAKE3 identity against the raw bytes.

pub fn read_chunk(&mut self, index: u32) -> Result<Vec<u8>>

Read, decompress and verify one chunk payload.

pub fn segment_bytes(&mut self, segment: &SegmentRecord) -> Result<Vec<u8>>

Reconstruct a segment payload: ordered concatenation of its chunks.

pub fn track_init_bytes(&mut self, track_id: u32) -> Result<Vec<u8>>

Reconstruct a track’s init payload (e.g. CMAF init segment).

pub fn embedded_signature(&self) -> Option<([u8; 64], [u8; 32])>

Embedded content signature (sig, pubkey) if present, parsed from meta.

pub fn verify_signature(&self) -> Result<SignatureStatus>

Check the embedded Ed25519 content signature, if any. Returns Unsigned when absent, Valid(pubkey) when it verifies, and an error when present but invalid. Callers decide whether the returned pubkey is trusted.

pub fn verify(&mut self) -> Result<VerifyReport>

Full verification: every chunk hash, the Merkle root against the integrity section, and the DATA section hash from the directory.
