Struct PackManifest 

pub struct PackManifest { /* private fields */ }

In-memory manifest for fast verify(uuid, &bytes) lookups.

Implementations

impl PackManifest

pub fn new() -> Self

Empty manifest — writer accumulates entries through Self::insert.

pub fn insert(&mut self, uuid: AssetUUID, bytes: &[u8])

Hashes bytes with BLAKE3, records the digest under uuid.

pub fn encode(&self) -> Result<Vec<u8>>

Encodes the manifest into the on-disk byte vector.

pub fn decode(bytes: &[u8]) -> Result<Self>

Decodes the on-disk byte vector into a manifest ready for lookup.

pub fn is_empty(&self) -> bool

Returns true if the manifest contains no entries.

pub fn len(&self) -> usize

Number of recorded entries.

pub fn get(&self, uuid: &AssetUUID) -> Option<&ManifestEntry>

Retrieve the recorded hash + size for uuid.

pub fn verify(&self, uuid: &AssetUUID, bytes: &[u8]) -> Result<()>

Verifies bytes against the recorded hash for uuid. Returns Ok(()) on match, Err on mismatch (or if the uuid is not in the manifest — the caller chose to verify but the record is missing).
