Usages

        env::set_var("INTL_RS_DIR", "languages");
        let key = "hello.world";

        assert_eq!(t!(key), "你好，世界！");

        assert_eq!(
            t!("unknown key", default:"default message"),
            "default message"
        );

        //default to ensure fallback
        //and you can disable it by disable_fallback function
        let configs = I18nConfig {
            fallback: None,
            locale: Some("en".to_owned()),
            null_placeholder: None,
        };
        assert_eq!(t!(key, configs: configs), "Hello,World!");

        let configs = I18nConfig {
            fallback: Some(true),
            locale: Some("en_UK".to_owned()),
            null_placeholder: None,
        };
        assert_eq!(t!(key, configs: configs), "Hello,World!");

        //change the default null placeholder
        let configs = I18nConfig {
            fallback: Some(true),
            locale: Some("en_UK".to_owned()),
            null_placeholder: Some("".to_owned()),
        };
        assert_eq!(t!("unknown key", configs: configs), "");
