Struct Manifest 

pub struct Manifest { /* private fields */ }

A slice manifest (15.13, spec-0.4.0): {"members": [...], "slice": {...}}, the member receipt hashes (ascending, unique, at most 1,048,576) and the slice object. It is fetched by its entry slice:<slice id>:<members hash>, where the members hash is SHA-256 of the canonical bytes of the members array (of [] for an empty slice).

Implementations

impl Manifest

pub fn from_json(bytes: &[u8]) -> Result<Manifest>

Parses a manifest from JSON text: strict JSON; structure (E_SCHEMA) over the whole manifest, the slice object’s included; then the members (E_CANON_HEX for each, then E_CANON_SET for their order, then E_CANON_LIMIT), then the slice object (see Slice::from_json).

pub fn from_value(v: &Value) -> Result<Manifest>

Checks a parsed JSON value as a manifest.

pub fn new(slice: Slice, members: Vec<String>) -> Result<Manifest>

The manifest of slice with members (receipt hashes), checked as from_json checks them: each 64 lowercase hex digits (E_CANON_HEX), strictly ascending (E_CANON_SET), at most 1,048,576 (E_CANON_LIMIT).

pub fn slice(&self) -> &Slice

The slice object.

pub fn members(&self) -> &[String]

The member receipt hashes, ascending.

pub fn members_hash(&self) -> &str

SHA-256 of the canonical bytes of the members array, lowercase hex.

pub fn entry(&self) -> String

The inputs entry that cites this manifest: slice:<slice id>:<members hash>.

pub fn to_value(&self) -> Value

The JSON form.

pub fn canonical(&self) -> Vec<u8>

The canonical bytes (6.2).
