Expand description
State maintained about individual collections.
Fields
description: CollectionDescription<T>
Description with which the collection was created
read_capabilities: MutableAntichain<T>
Accumulation of read capabilities for the collection.
This accumulation will always contain self.implied_capability
, but may also contain
capabilities held by others who have read dependencies on this collection.
implied_capability: Antichain<T>
The implicit capability associated with collection creation. This should never be less than the since of the associated persist collection.
read_policy: ReadPolicy<T>
The policy to use to downgrade self.implied_capability
.
write_frontier: Antichain<T>
Reported write frontier.
collection_metadata: CollectionMetadata
