Struct mz_storage::source::persist_source::DropSafeLeaseStream
source · [−]struct DropSafeLeaseStream {
pinned_stream: Option<Pin<Box<dyn FuturesStream<Item = Result<(Vec<LeasedBatchPart<Timestamp>>, Antichain<Timestamp>), ExternalError>> + Send>>>,
}
Expand description
The stream of batches from persist cannot be dropped at the discretion of
the program unaided without potentially panicking (check LeasedBatchPart
).
To prevent panics, ensure that all of the stream’s values are consumed,
irrespective of the source getting dropped.
Fields
pinned_stream: Option<Pin<Box<dyn FuturesStream<Item = Result<(Vec<LeasedBatchPart<Timestamp>>, Antichain<Timestamp>), ExternalError>> + Send>>>
