Struct ReceiptId 

pub struct ReceiptId(pub Uuid);

Identifies one operational receipt derived from committed events.

Tuple Fields

0: Uuid

Implementations

impl ReceiptId

pub fn derive(event_ids: &[EventId], status_code: &str) -> ReceiptId

Derives the identifier of a receipt from the events it cites and its status code.

Receipts are deterministic (spec §17.3): the same committed events rendered again are the same receipt, so a replayed turn produces the same identifiers and claim_guard::verify can refuse two different receipts that claim to be one.

The event order does not change the result; the set does.

impl ReceiptId

pub fn new() -> ReceiptId

Generates a new time-ordered (UUID v7) identifier.

Identifiers that must be reproducible across a replay are derived instead: see derive on the types that have one.

pub const fn nil() -> ReceiptId

The all-zero identifier, useful as a sentinel in tests and fixtures.

pub const fn as_uuid(&self) -> &Uuid

Returns the underlying UUID.

pub fn is_nil(&self) -> bool

Returns true when this is the nil identifier.
