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: mod.rs
    path of file: ./repos/reth/crates/primitives/src/transaction
    
    the code of the file until where you have to start completion: use crate::{
    compression::{TRANSACTION_COMPRESSOR, TRANSACTION_DECOMPRESSOR},
    keccak256, Add
    
    fn min_length_encoded_deposit_transaction() {
        use super::MIN_LENGTH_DEPOSIT_TX_ENCODED;
        use crate::TxDeposit;

        let transaction = TxDeposit::default();
        let signature = Signature::default();

        let signed_tx = TransactionSigned::from_transaction_and_signature(
            Transaction::Deposit(transaction),
            signature,
        );

        let mut encoded = BytesMut::new();
        signed_tx.encode(&mut encoded);

        assert_eq!(b"\xb8?~\xf8<\xa0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\x94\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\x80\x80\x80\x80\x80\x80", &encoded[..]);
        assert_eq!(MIN_LENGTH_DEPOSIT_TX_ENCODED, encoded.len());

        TransactionSigned::decode(&mut &encoded[..]).unwrap();
    }
