Module options

Structs§

ConsensusPruningOptions: Pruning parameters for ephemeral consensus storage.
Options: Options for database-backed persistence, supporting both Postgres and SQLite.
PostgresOptions: Options for Postgres-backed persistence.
PruningOptions: Pruning parameters.
SerializableRetryOptions: Configuration for retrying transactions aborted by PostgreSQL serialization conflicts (error 40001). Under SERIALIZABLE isolation these aborts are expected and safe to retry from scratch.
SqliteOptions

SqlBackendOptions: Options wrapped for the backend Options::embedded_db selects.
SqlPool 🔒: A connection pool for whichever backend Options::embedded_db selects.

DECIDE_GAP_FILL_HORIZON 🔒: How far behind the newest persisted decide an out-of-order (“gap-fill”) decide can still arrive. Mirrors DECIDE_BUFFER in hotshot-new-protocol; a leaf missing further behind the watermark than this will never be filled in by consensus.
DEFAULT_ARCHIVE_STATE_MIN_RETENTION: A few days of heights at mainnet rates, and what binds whenever the light client’s history is shorter than that.

build_sqlite_path: The path of the SQLite database under the base directory path.
within_gap_fill_horizon 🔒: Whether the height gap directly below the leaf at view can still be filled by a late decide: the missing view (at most view - 1) must be within DECIDE_GAP_FILL_HORIZON of watermark, the newest persisted decide.
