Trait BackfillSource 

pub trait BackfillSource: Send + Sync {
    // Required method
    fn backfill_range<'life0, 'async_trait>(
        &'life0 self,
        start_height_inclusive: u64,

       where Self: 'async_trait,
             'life0: 'async_trait;
}

Produces historical updates in height ranges for backfilling.

Implementations should chunk internally as needed and respect cancellation_token promptly. All emitted updates must have heights within the requested inclusive range.

Required Methods

fn backfill_range<'life0, 'async_trait>( &'life0 self, start_height_inclusive: u64, end_height_inclusive: u64, sender: Sender<(Updates, DatasourceId)>, cancellation_token: CancellationToken, metrics: Arc<MetricsCollection>, ) -> Pin<Box<dyn Future<Output = IndexerResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Backfill updates from start_height_inclusive to end_height_inclusive.
