Trait DataBackend 

pub trait DataBackend<IS: InstrumentSpec> {
    // Required methods
    fn new(key: Option<&str>) -> Self;
    fn file_name_postpend() -> &'static str;
    fn stream_in(
        &mut self,
        buf_reader: BufReader<File>,
    ) -> impl Future<Output = impl ExactSizeIterator<Item = TradeTradeTimestamp<IS>>> + Send;
}
