Struct Manifest 

pub struct Manifest {
    pub version: u32,
    pub model_repo: String,
    pub root_hash: String,
    pub directories: BTreeMap<String, DirEntry>,
    pub files: BTreeMap<String, FileEntry>,
}

Persistent manifest tracking all indexed files and their state.

Fields

version: u32

Cache format version (bump to invalidate all caches).

model_repo: String

The embedding model used to generate this index.

root_hash: String

Root Merkle hash (changes when any file changes).

directories: BTreeMap<String, DirEntry>

Directory entries with mtime and computed Merkle hash.

files: BTreeMap<String, FileEntry>

File entries with metadata and content hash.

Implementations

impl Manifest

pub fn new(model_repo: &str) -> Self

Create a new empty manifest for the given model.

pub fn add_file( &mut self, relative_path: &str, mtime_secs: u64, size: u64, content_hash: &str, chunk_count: usize, )

Register a file in the manifest.

pub fn remove_file(&mut self, relative_path: &str)

Remove a file from the manifest.

pub fn recompute_hashes(&mut self)

Recompute all directory hashes and the root hash bottom-up.

For each directory, the hash is blake3 of the sorted children’s content hashes concatenated. The root hash is blake3 of all top-level entries.

pub fn to_json(&self) -> Result<String>

Serialize to JSON string.

Errors

Returns an error if serialization fails.

pub fn from_json(json: &str) -> Result<Self>

Deserialize from JSON string.

Errors

Returns an error if the JSON is invalid.

pub fn save(&self, path: &Path) -> Result<()>

Save manifest to a file.

Errors

Returns an error if the file cannot be written.

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

Load manifest from a file.

Errors

Returns an error if the file cannot be read or parsed.

pub fn is_compatible(&self, model_repo: &str) -> bool

Check whether this manifest is compatible with the given model.

pub fn referenced_hashes(&self) -> Vec<String>

Collect all content hashes referenced by files in this manifest.

Trait Implementations

impl Debug for Manifest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Manifest

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Manifest

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
