Function vault_id 

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

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

Vault ledger entry IDs are used to reference vault 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 vault’s owner
• seq - The account sequence associated with the vault entry

Returns

• Result<LedgerEntryIdBytes> - On success, returns a 32-byte vault 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::vault_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::vault_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 sequence = 12345;
  match vault_id(&account, 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(())
}
