Function sponsorship_id 

pub fn sponsorship_id(
    sponsor: &AccountID,
    sponsee: &AccountID,
) -> Result<LedgerEntryIdBytes>

Generates a sponsorship ledger entry ID for a given sponsor and sponsee in the XRP Ledger.

Sponsorship ledger entry IDs are used to reference sponsorship 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

• sponsor - Reference to an AccountID representing the sponsoring account
• sponsee - Reference to an AccountID representing the sponsored account

Returns

• Result<LedgerEntryIdBytes> - On success, returns a 32-byte sponsorship 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::sponsorship_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::sponsorship_id;
use xrpl_common_stdlib::host::trace::{ trace_hex, trace_num };

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