Expand description

A digester than can compute the digest used for mithril signatures

If you want to mock it using mockall:

mod test {
    use async_trait::async_trait;
    use mithril_common::digesters::{ImmutableDigester, ImmutableDigesterError};
    use mithril_common::entities::CardanoDbBeacon;
    use mockall::mock;
    use std::path::Path;

    mock! {
        pub ImmutableDigesterImpl { }

        #[async_trait]
        impl ImmutableDigester for ImmutableDigesterImpl {
            async fn compute_digest(
              &self,
              dirpath: &Path,
              beacon: &CardanoDbBeacon,
            ) -> Result<String, ImmutableDigesterError>;
        }
    }

    #[test]
    fn test_mock() {
        let mut mock = MockDigesterImpl::new();
        mock.expect_compute_digest().return_once(|_, _| {
            Err(ImmutableDigesterError::NotEnoughImmutable {
                expected_number: 3,
                found_number: None,
                db_dir: PathBuff::new(),
            })
        });
    }
}
