Expand description
State maintained about individual collections.
Fields
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.
read_policy: ReadPolicy<T>
The policy to use to downgrade self.implied_capability
.
write_frontier: MutableAntichain<T>
Reported progress in the write capabilities.
Importantly, this is not a write capability, but what we have heard about the
write capabilities of others. All future writes will have times greater than or
equal to write_frontier.frontier()
.
