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: lib.rs
    path of file: ./repos/ink/integration-tests/contract-terminate
    
    the code of the file until where you have to start completion: //! A smart contract which demonstrates behavior of the `self.env().terminate()`
//! function. It terminates itself once `terminate_me()` is called.

#![cfg_attr(not(feature = "std"), no_std, no_main)]
#![allow(clippy::new_without_default)]

#[ink::contract]
pub mod just_terminates {
    /// No storage is needed for this simple contract.
    #[ink(storage)]
    pub struct JustTerminate {}

    impl JustTerminate {
        /// Creates a new instance of this contract.
 
    
        fn terminating_works() {
            // given
            let accounts =
                ink::env::test::default_accounts::<ink::env::DefaultEnvironment>();
            let contract_id = ink::env::test::callee::<ink::env::DefaultEnvironment>();
            ink::env::test::set_caller::<ink::env::DefaultEnvironment>(accounts.alice);
            ink::env::test::set_account_balance::<ink::env::DefaultEnvironment>(
                contract_id,
                100,
            );
            let mut contract = JustTerminate::new();

            // when
            let should_terminate = move || contract.terminate_me();
