You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: app.rs
    path of file: ./repos/ethers-rs/ethers-signers/src/ledger
    
    the code of the file until where you have to start completion: #![allow(unused)]
use coins_ledger::{
    common::{APDUAnswer, APDUCommand, APDUData},
    transports::{Ledger, LedgerAsync},
};
use futures_executor::block_on;
use futures_util::lock::Mutex;

use ethers_core::{
    types::{
        transaction::{eip2718::TypedTransaction, eip712::Eip712},
        Address, NameOrAddress, Signature, Transacti
    
    async fn test_get_address() {
        // Instantiate it with the default ledger derivation path
        let ledger = LedgerEthereum::new(DerivationType::LedgerLive(0), 1).await.unwrap();
        assert_eq!(
            ledger.get_address().await.unwrap(),
            "eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee".parse().unwrap()
        );
        assert_eq!(
            ledger.get_address_with_path(&DerivationType::Legacy(0)).await.unwrap(),
            "eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee".parse().unwrap()
        );
    }
