Struct DeliveryConfirmation 

pub struct DeliveryConfirmation { /* private fields */ }

Confirmation that a counterparty durably received one Event Message.

This is not an Event Message: event_id identifies the original event, not this confirmation. Delivery Confirmations must never be confirmed. They do not indicate payment acceptance, execution, or settlement.

The caller owns durable receipt and sends this over the authenticated Encrypted Link to the original sender only after persisting the event.

Implementations

impl DeliveryConfirmation

pub fn new( app_id: PaykitAppId, event_id: EventId, payload_hash: String, ) -> Result<Self>

Create a version-1 confirmation for an existing Event Message.

app_id is the local confirming App, and event_id is the original Event ID. payload_hash must be SHA-256 of the exact raw UTF-8 original JSON, including whitespace, formatted as sha256:<64 lowercase hex>. This validates the hash’s format; the caller computes it without reserializing the original JSON and confirms only Event Message kinds.

pub fn app_id(&self) -> &PaykitAppId

Local App confirming durable receipt of the original Event Message.

pub fn event_id(&self) -> &EventId

Original Event ID; no fresh Event ID is allocated for this confirmation.

pub fn payload_hash(&self) -> &str

SHA-256 of the exact raw UTF-8 original JSON, prefixed with sha256:.
