DbKindAuthored
Specifies the environment used for authoring data by all cells on the same DnaHash.
DbKindCache
Specifies the environment used by each Cache (one per dna).
DbKindConductor
Specifies the environment used by a Conductor
DbKindDht
Specifies the environment used for dht data by all cells on the same DnaHash.
DbKindP2pAgents
State of the p2p network (one per space).
DbKindP2pMetrics
Metrics for peers on p2p network (one per space).
DbKindWasm
Specifies the environment used to save wasm
DbRead
A read-only version of DbWrite. This environment can only generate read-only transactions, never read-write.

OptimisticRetryError
PConnGuard
PConnPermit

DbKind
The various types of database, used to specify the list of databases to initialize
DbSyncLevel
The sqlite synchronous level. Corresponds to the PRAGMA synchronous pragma. See sqlite documentation.
DbSyncStrategy
The strategy for database file system synchronization. Some databases like the cache can be safely rebuilt if corruption occurs due to using the faster DbSyncLevel::Off.

AsP2pAgentStoreConExt
Extension trait to treat connection instances as p2p store accessors.
AsP2pMetricStoreConExt
AsP2pMetricStoreTxExt
AsP2pStateTxExt
Extension trait to treat transaction instances as p2p store accessors.
DbKindOp
DbKindT
PermittedConn
ReadAccess
A trait for being generic over DbWrite and DbRead that both implement read access.
ReadManager
Implementors are able to create a new read-only DB transaction
WriteManager
