Function paychan_id 

pub fn paychan_id(
    account: &AccountID,
    destination: &AccountID,
    seq: u32,
) -> Result<LedgerEntryIdBytes>

Generates a payment channel ledger entry ID for a given owner and sequence in the XRP Ledger.

Payment channel ledger entry IDs are used to reference payment channel 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

• account - Reference to an AccountID representing the payment channel sender’s account
• destination - Reference to an AccountID representing the payment channel’s destination
• seq - The account sequence associated with the payment channel entry

Returns

• Result<LedgerEntryIdBytes> - On success, returns a 32-byte payment channel 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::paychan_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::paychan_id;
use xrpl_common_stdlib::host::trace::{ trace_hex, trace_num };

fn main() -> Result<(), Box<dyn std::error::Error>> {
  let account: AccountID =
      AccountID::from(*b"\xd5\xb9\x84VP\x9f \xb5'\x9d\x1eJ.\xe8\xb2\xaa\x82\xaec\xe3");
  let destination: AccountID =
      AccountID::from(*b"\xd5\xb9\x84VP\x9f \xb5'\x9d\x1eJ.\xe8\xb2\xaa\x82\xaec\xe3");
  let sequence = 12345;
  match paychan_id(&account, &destination, 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(())
}
