Structs

• 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.
• DbWrite
  The canonical representation of a (singleton) database. The wrapper contains methods for managing transactions and database connections,
• PTxnGuard
  Newtype to hand out connections that can only be used for running transactions

Enums

• DatabaseError
• 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.

Traits

• AsP2pMetricStoreTxExt
• AsP2pStateReadExt
  Extension trait to treat database read handles as p2p store accessors.
• AsP2pStateTxExt
  Extension trait to treat transaction instances as p2p store accessors.
• AsP2pStateWriteExt
  Extension trait to treat database write handles as p2p store accessors.
• DbKindOp
• DbKindT
• FallibleIterator
  An Iterator-like trait that allows for calculation of items to fail.
• ReadAccess
  A trait for being generic over DbWrite and DbRead that both implement read access.

Functions

• num_read_threads
• p2p_prune
  Prune all expired AgentInfoSigned records from the p2p_store
• p2p_put
  Put an AgentInfoSigned record into the p2p_store
• p2p_put_all
  Put an iterator of AgentInfoSigned records into the p2p_store
• p2p_put_single
  Insert a p2p record from within a write transaction.
• set_acquire_timeout
• set_connection_timeout
