Struct UpdateParty 

pub struct UpdateParty {
    pub transaction_id: String,
    pub party_type: String,
    pub party: Party,
    pub context: Option<String>,
}

UpdateParty message body (TAIP-6).

This message type allows agents to update party information in a transaction. It enables a participant to modify their details or role within an existing transfer without creating a new transaction. This is particularly useful for situations where participant information changes during the lifecycle of a transaction.

TAIP-6 Specification

The UpdateParty message follows the TAIP-6 specification for updating party information in a TAP transaction. It includes JSON-LD compatibility with an optional @context field.

Example

use tap_msg::message::update_party::UpdateParty;
use tap_msg::message::Party;
use std::collections::HashMap;

// Create a party with updated information
let updated_party = Party::new("did:key:z6MkpDYxrwJw5WoD1o4YVfthJJgZfxrECpW6Da6QCWagRHLx")
    .with_country("de");

// Create an UpdateParty message
let update_party = UpdateParty::new(
    "transfer-123",
    "originator",
    updated_party
);

Fields

transaction_id: String

ID of the transaction this update relates to.

party_type: String

Type of party being updated (e.g., ‘originator’, ‘beneficiary’).

party: Party

Updated party information.

context: Option<String>

Optional context for the update.
