Function oracle_id 

pub fn oracle_id(
    owner: &AccountID,
    document_id: u32,
) -> Result<LedgerEntryIdBytes>

Generates an oracle ledger entry ID for a given owner and document ID in the XRP Ledger.

Oracle ledger entry IDs are used to reference oracle 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 oracle owner’s account
• document_id - An integer identifier for the oracle document

Returns

• Result<LedgerEntryIdBytes> - On success, returns a 32-byte oracle 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::oracle_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::oracle_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 document_id = 12345;
  match oracle_id(&owner, document_id) {
    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(())
}
