Struct Receipt 

pub struct Receipt { /* private fields */ }

A receipt (8.1) that has passed verification steps 1-4: strict JSON, structure, canonical form and consistency. Its signature has not been checked; use crate::verify.

The members are private and read through getters, so the cached payload and hash always describe them. A Receipt comes only from from_json (or from_value for JSON already parsed) and, with feature sign, from ReceiptBuilder::sign.

Implementations

impl Receipt

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

Parses a receipt and runs verification steps 1-4 (10.1).

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

Runs verification steps 2-4 on a parsed JSON value.

pub fn payload(&self) -> &[u8]

The signed payload: canonical bytes of the receipt without sig (8.3).

pub fn hash(&self) -> &str

The receipt hash: SHA-256 of the payload, lowercase hex (8.3).

pub fn asof(&self) -> &str

The transaction time answered as of.

pub fn cell(&self) -> &Cell

The cell answered (no slices).

pub fn computed_by(&self) -> &str

<host>#<key id> of the signing key.

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

The inputs entries, ascending: receipt hashes and, since spec-0.4.0, slice entries slice:<slice id>:<members hash> (which sort after every receipt hash).

pub fn issued(&self) -> &str

When the receipt was signed.

pub fn licence(&self) -> &str

An SPDX identifier or an https URL.

pub fn publisher(&self) -> &str

The namespace that owns the function; equals cell.ns.

pub fn sig(&self) -> &str

The Ed25519 signature, 128 lowercase hex digits.

pub fn summary(&self) -> &str

One human sentence.

pub fn tx(&self) -> &str

When the value was recorded.

pub fn value(&self) -> &Scalar

The value, typed.

pub fn valid(&self) -> &Args

The valid-time arguments, echoed from cell.args.

pub fn ty(&self) -> Type

The value’s type (the type member).

pub fn signer_host(&self) -> &str

The host of computed_by.

pub fn key_id(&self) -> &str

The key id of computed_by.
