Function mptoken_id 

pub fn mptoken_id(
    mptid: &MptId,
    holder: &AccountID,
) -> Result<LedgerEntryIdBytes>

Generates an MPToken ledger entry ID for a given MPT ID and holder.

An MPToken ledger entry ID is used to reference MPToken entries in the XRP Ledger.

Arguments

• mptid - The MPT ID that the MPToken is associated with
• holder - The AccountID of the account that holds the MPToken

Returns

• Result<LedgerEntryIdBytes> - On success, returns a 32-byte MPToken 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::mptoken_id function.

Example

use xrpl_common_stdlib::types::account_id::AccountID;
use xrpl_common_stdlib::types::mpt_id::MptId;
use xrpl_common_stdlib::ledger_entry_ids::mptoken_id;
use xrpl_common_stdlib::host::trace::{ trace_hex, trace_num };
fn main() -> Result<(), Box<dyn std::error::Error>> {
    let issuer: AccountID =
        AccountID::from(*b"\xd5\xb9\x84VP\x9f \xb5'\x9d\x1eJ.\xe8\xb2\xaa\x82\xaec\xe3");
    let mptid: MptId = MptId::new(1, issuer);
    let holder: AccountID =
        AccountID::from(*b"\xd5\xb9\x84VP\x9f \xb5'\x9d\x1eJ.\xe8\xb2\xaa\x82\xaec\xe3");
    match mptoken_id(&mptid, &holder) {
      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(())
}
