class Manifest
Manifest(url: str, sha256_content: str, bytes: int, fetched_at: str, etag: Optional[str] = None, last_modified: Optional[str] = None, source_loader: Optional[str] = None, auth_realm: Optional[str] = None, schema: str = MANIFEST_SCHEMA_TAG)
Manifest.to_dict() -> dict
Manifest.to_json() -> str
@classmethod Manifest.from_dict(obj: dict) -> 'Manifest'
@classmethod Manifest.from_json(text: str) -> 'Manifest'

In-memory view of meta/<key>.json (see the schema for field meanings).

Members

to_dict — All nine fields, always present (the key carries null when N/A).
to_json — Serialize exactly as the corpus does: sorted keys, indent 2, newline.

struct Manifest
Manifest(url::String, etag::Union{Nothing, String}, last_modified::Union{Nothing, String}, sha256_content::String, bytes::Int64, fetched_at::String, source_loader::Union{Nothing, String}, auth_realm::Union{Nothing, String})
Manifest(url, etag, last_modified, sha256_content, bytes, fetched_at, source_loader, auth_realm)

Manifest

Validation + provenance record for one cached blob. Field mapping (bead → here): source-url → url, etag → etag, checksum → sha256_content, fetched-at → fetched_at, byte-size → bytes.

Source

Rust

pub struct Manifest {
    pub auth_realm: Option<String>,
    pub bytes: u64,
    pub etag: Option<String>,
    pub fetched_at: String,
    pub last_modified: Option<String>,
    pub schema: String,
    pub sha256_content: String,
    pub source_loader: Option<String>,
    pub url: String,
}

impl Manifest { pub fn to_json_bytes(&self) -> Result<Vec<u8>> }

impl Manifest { pub fn from_json_bytes(data: &[u8]) -> Result<Manifest> }

impl Manifest { pub fn read(path: &Path) -> Result<Manifest> }

Validation + provenance record stored alongside every cached blob.

url, sha256_content, bytes, and fetched_at are required; the remaining fields are always present but may be null. Credentials are never stored — only the auth_realm name.
