Function mpt_issuance_id 

pub fn mpt_issuance_id(
    owner: &AccountID,
    seq: u32,
) -> Result<LedgerEntryIdBytes>

Generates an MPT issuance ledger entry ID for a given owner and sequence in the XRP Ledger.

MPT issuance ledger entry IDs are used to reference MPT issuance entries in the XRP Ledger’s state data. This function uses the generic create_id_from_host_call helper to manage the FFI interaction.

Arguments

• owner - Reference to an AccountID representing the MPT issuer’s account
• seq - The account sequence associated with the MPT issuance entry

Returns

• Result<LedgerEntryIdBytes> - On success, returns a 32-byte MPT issuance ledger entry ID. On failure, returns an Error with the corresponding error code.

Safety

This function makes unsafe FFI calls to the host environment through the host::mpt_issuance_id function, though the unsafe code is contained within the closure passed to create_id_from_host_call.

Example

use xrpl_common_stdlib::types::account_id::AccountID;
use xrpl_common_stdlib::ledger_entry_ids::mpt_issuance_id;
use xrpl_common_stdlib::host::trace::{ trace_hex, trace_num };

fn main() -> Result<(), Box<dyn std::error::Error>> {
  let owner: AccountID =
      AccountID::from(*b"\xd5\xb9\x84VP\x9f \xb5'\x9d\x1eJ.\xe8\xb2\xaa\x82\xaec\xe3");
  let sequence = 12345;
  match mpt_issuance_id(&owner, sequence) {
    xrpl_common_stdlib::host::Result::Ok(id) => {
      trace_hex("Generated ledger entry ID", &id);
    }
    xrpl_common_stdlib::host::Result::Err(e) => {
      trace_num("Error assembling ledger entry ID", e.code() as i64);
    }
  }
  Ok(())
}
