Expand description

A scanner that can read cardano transactions in a cardano database

If you want to mock it using mockall:

mod test {
    use std::path::Path;

    use anyhow::anyhow;
    use async_trait::async_trait;
    use mockall::mock;

    use mithril_common::cardano_block_scanner::{BlockScanner, BlockStreamer, RawCardanoPoint};
    use mithril_common::entities::{BlockNumber};
    use mithril_common::StdResult;

    mock! {
        pub BlockScannerImpl { }

        #[async_trait]
        impl BlockScanner for BlockScannerImpl {
            async fn scan(
              &self,
              from: Option<RawCardanoPoint>,
              until: BlockNumber,
            ) -> StdResult<Box<dyn BlockStreamer>>;
        }
    }

    #[test]
    fn test_mock() {
        let mut mock = MockBlockScannerImpl::new();
        mock.expect_scan().return_once(|_, _| {
            Err(anyhow!("parse error"))
        });
    }
}
